MediCrystal AMETHYST TOURMALINE HOT STONE BIO-MAGNETIC... User manual

First you should tightly connect controller to the mat connector and
only aer this plug-in controller into the power outlet. Then turn ON
controller with toggle switch.
Controller has a temperature dial to completely adjust the heat in
1°C increments from 86 °F to 158 °F, displayed in Celsius from 30 °C
to 70 °C. Sometimes we call the dierent temperatures “levels”.
Level 1 is 86-98 °F or 30-36 °C (Lowest mode, reveals crystals’ powers
and brings negative ions and other vital natural forces into your home while
you are seeking rest and mental clarity, great to sleep or relax).*
Level 2 is 98-110 °F or 36-43 °C (Low mode, provides a comfortable
setting for all night restful sleep to manage an occasional sleeplessness,
improve absentmindedness, relieve tiredness, and maintain proper
immune function).*
Level 3 is 110-120 °F or 43-49 °C (Low medium mode, great to
create maximum relaxation and immunity support environment, helpful
to maintain healthy heart, inspired and invigorated mind, improve look
of your skin).*
Level 4 is 120-133 °F or 49-56 °C (Medium mode, use as a part
of your dietary and healthy routine to maintain cholesterol and sugar
levels already within the normal range, alleviate the occasional blue
feeling everyone experiences from time to time).*
Level 5 is 133-145 °F or 56-63 °C (Medium High mode, may be helpful
for healthy lifestyle to alleviate occasional constipation, promote
sexual arousal and performance, relieve temporary water-weight gain
and mild mood changes bringing you back to normal condition).*
Level 6 is 145-158 °F or 63-70 °C (High mode, envelop yourself with
pleasant warmth of natural crystals and gemstones. Together with exercise
patterns it may encourage activity, contribute to spiritual balance, feeling
happy, cleansing, sweating, well-being and better overall health).*
Level 7 is 158 °F or 70 °C (Highest mode, use with extra care to create
maximum soothing environment important for proper muscles and joints
function, optimal strength and exibility, stress and tension reduction).
The temperatures reect the temperature of the inner heating
elements, not the surface of the mat, which can be 10-20 °F lower (or
even lower than this) if the mat is not covered with a thick blanket.
Usually, if the ambient temperature is around 70 °F, it takes between a
half an hour to hour for the mat to reach the maximum level (158 °F,
or 70 °C) if covered it with a thick blanket.

1. The top of the mat, with the MediCrystal® Logo on it, is not a
heated area but this and other non-heated areas of the mat still
have anion layers to generate negative ions.
2. PEMF coils are distributed throughout the mat but their number
is limited (starting from 2-3 coils in the mini mat and up to 8-10
coils in full size mats). Magnetic eld intensity is the strongest
above the coil but goes down with distance. It is normal that your
PEMF tester will show metal piece movements in some spots of
your mat and will not in other.
3. Standard PEMF frequency of MediCrystal® mats with bio-magnetic
function is 10 Hz. If your mat or belt features H-60VA controller,
you will usually have a manual adjustability between 1 to 30
magnetic pulsations per second and several auto programs of
dierent very low frequencies sets cycling ON/OFF with the
total loop duration from 40-60 min to several hours. Usually
higher frequencies have more energizing eect and lower may be
better to relax but it is better to self-educate and listen your body’s
response to nd what works for you the best.
4. MediCrystal® mats have a multilayer system construction with up
to 18 dierent layers. The special layers (with anion generating
bers) are added so that the mats generate negative ions
when they are turned on and functioning. Controllers do not have
the option to activate negative ion generation from the inner mat
layers because the ions generation starts automatically when the
mat is heating up, due to the piezoelectric and pyroelectric eects
caused by the distorted crystallographic structure of the mat’s anion
generating layers and natural amethyst, jade, agate and tourmaline
ceramic stone disks. Negative ion generation will decrease when the
mat cools down. The number of ions goes up when you lay on
the non-powered mat as gemstones and negative ion generating
layers start to use your natural body heat to produce anions.
5. The outlets, bimetal safety switches, connectors, and controllers
of all electrical appliances including all brands of hot stone mats
may emit relatively higher levels up to 4-8 mG. Though it is
generally safe, and falls down to zero several inches away, if you
are EMF oversensitive, it is better to keep the controller away
from your head. Also, it is better to use the amethyst pillow or
at least a regular one to avoid occasional contacts between your
head and the mat connector near the logo on the top of the mat.
Or you can lay on the mat with your feet towards the connector.
If you do not feel comfortable on the powered mat, you can
eliminate exposure to any electricity just by preheating your
stone mattress to the maximum heat and unplugging it from
the power outlet before you lie on it. Hot crystals accumulate
the warmth and will naturally release it without electric power. It is
the best practice for long all-night sessions to avoid dehydration,
overstimulation, and buzz or dry mouth eects. Even aer the
mat cools down, it utilizes your body warmth to emit infrared rays
and negative ions naturally and safe.
6. We use the best in the industry advanced EMF-free heating
systems since 2016. Though the specication states maximum
2 mG emission from the heating surface, the real tests with
professional EMFs measuring devices show max 0.2 mG emission.
It is even closer to zero because when we test the background
EMFs on the unplugged mat, it is usually the same as on the
heating mat. You can check our videos for EMFs measurements on
MediCrystal youtube channel. Please disregard outdated, false or
non-professional information or videos about EMFs testing posted
on the internet by unfair competitors. Fortunately, nowadays the
testers are aordable for everyone, and the best practice is to check
EMFs of the mat and other home appliances yourself. The best EMFs
meters for home use combine simplicity, sensitivity to electric and
magnetic waves in a broad range, and ability to lter out the noise
distortions or measurement errors. We recommend an easy to use
the “K2 EMFs meter” manufactured in the U.S. and available on
Amazon for $60. This meter covers frequencies from 50 to 20,000
Hz and works ne instantly measuring EMFs of any appliances.
7. PEMF coils of our bio-magnetic mats generate pulsed magnetism
when the function is ON. The intensity of these healthful dynamic
magnetic waves rapidly changes from 0 to 50 Gauss 1-30 times per
second similar to the natural Earth’s geomagnetism pulsation known
as “Schumann resonance”. It is recognized as a safe reparative
technique, but if you test EMFs while the PEMF function is ON, the
results will be signicantly distorted. Of course, there is a huge
dierence between the healthful ultra low frequency magnetic elds
frequencies of 1-30 times per second or 1-30 Hz and the harmful
high EMFs frequencies in Khz and Mhz ranges such as emitted by
micro waves, heaters, wireless devices and radio equipment. You
can still use the K2 EMFs meter to test how far the magnetic forces
of your mat can penetrate. The meter indicators will be blinking
with the same frequency as PEMF setting. If you turn OFF the PEMF
function and test your bio-magnetic mat again, it will show the
same EMF-free zero results as all other our products.
8. Due to the artisan nature of the construction process there is some
dierence between mats regarding the maximum temperature
they may reach in the same conditions and the heating speed.
If the mat is covered with thick blanket or your body is on the
mat, the max level of the bare mat surface temperature may be in
the range of 55-65 °C or 133–158 °F (displayed by the controller
measuring the temperature of the heating elements inside the
mat as 65-72 °C), which is quite normal. It is very important
that you cover the mat COMPLETELY while preheating it. If
you cover the mat partially the temperature sensors positioned in
the dierent layers of the mat around all the surface will report
dierent and controvercial measurements to the main controller.
Finally controller may loose calibration and start to work incorrectly
or malfunction.
9. Both Mini V-Mat and Amethyst Tourmaline PEMF Belt (with
detachable heating pap) are great for localized use, when you need
to apply crystal rays and focus magnetism on some area (back or
legs most frequently) without overstimulating the whole body.
It is portable, more bendable, and can be used to cover the body
when you are on the large mat for the more intensive “sandwiched”
sessions. Of course, the Mini mat can still be used as a sole unit
for high heat sessions with sweating, but it takes more time to
inuence the body in this way. But if you use high temperature
and your body usually sweats in the sauna or when you do sports or
workout, the Mini will work ne as well.
10. In general the bigger and more powerful the mat is, more benets
it brings and the shorter the session necessary. Midsize and
larger mats are great for both the whole body experience and re-
energizing sleep. Just be sure that the heat level is on the safe,
lowest levels of 30-45 °C or use the mat either unpowered or
in negative-ions-only mode at night. Do not use high heat when
you go to bed. Do not rely solely on the timer. Some customers
choose to connect the mat through another timer plugged into the
the wall outlet for double safety in order not to fall asleep on the
hot mat and dehydrate. Take extra care during nighttime use and
keep the mat only on low heat settings.
MediCrystal® mats have been carefully engineered for both eectiveness
and safety. But of course basic safety precautions should always be
observed when using any electrical device.
1. Never immerse the mat in water, do not use the product in wet or
excessively humid areas. Do not use the device when your hands or
body are wet.
2. Changes or modications to the device can be dangerous and may
cause electric shock. Do not disassemble anything while the power
is ON.
3. Do not put heavy objects on the mat. Do not prick the mattress
with pins, knives or sharp objects. Do not step, walk, jump, run
and avoid other types of pressure which can damage inner sensors.
4. Do not put chemicals, solvents, volatile or ammable materials
such as benzene, thinner or kerosene on the mattress.
5. Make sure that the receptacle where you plan to plug the mat has
the same voltage rating as the specications indicated for each
product (usually 110-120V/60 Hz for North America and Japan and
220-250V/50 Hz for Europe and other countries). Do not use travel
adaptors in order not to damage your mat and controller.
6. If your mat is made for U.S. electricity, 110-120V/60 Hz, with plugs
for a standard U.S. grounded socket to use in 220-250V countries,
please purchase a step down power converter transforming 220-
240V to 110V. For smaller pads we recommend power converters
with 200-300W capacity, up to 500W for large mats and 1000W for
queen size mats with two heating zones.
7. Always remember to turn o the electrical supply when not in use.
When unplugging device, do not attempt to pull the cord, pull it
out by holding the plug.
8. To protect your mat, use a surge protector. Power spike is the main
reason why a mat would ever malfunction, an electrical surge kills
the controller and renders the mat unusable until a new controller
is purchased.
9. Do not use the device when the cord is damaged or if the electrical
outlet is excessively loose, nd another socket that will correctly
hold the plug. Do not use the mat if it is damaged or if connection
between the mat and controller is not tight.
10. Your mat has double safety advanced EMF free heating system
with emergency bimetal switches physically cutting o the
electrical wires if the mat’s main thermostat safety system fails
and it overheats to 180 °F (75 °C). Anyhow stop using and
immediately unplug the mat from its power source (wall outlet)
if you experience strange conditions such as smell, smoke, shocks
and/or re.
11. Remember that magnetic function can damage hardware storing
information. Avoid placing credit cards, phones, USB drives or
other similar items on the mats with biomagnetic function.
12. Clean the mat only when the power is o and the controller is
unplugged from the AC outlet.
13. While heating NEVER put on the mat foam, rubber, yoga, camp
pads, mats, non-permeable covers or too thick (more than one
inch) plies of towels or heavy blankets to avoid overheating,
malfunction and re risks. If the topper you use on the heating
mat is not permeable (like rubber), it will trap the FIR heat, and the
mat will regularly overheat. Though, in this case, bimetal switches
cut-o electricity, when they work permanently, they wear o fast,
and the re danger goes up. This safety feature is designed to stop
the mat overheating only in emergency case if the controller fails.
It is not intended to operate as the main thermostat. If the whole
mat is covered with non-permeable material and continuously
overheats, the bimetal switches function all the time and wear-
o. If they fail, the mat will not be protected from overheating or
re risks.
14. NEVER leave your mat unattended while heating up. NEVER heat
it in folded or rolled condition. NEVER put any solid objects such
as pillows, laptops, books, controllers, bags, etc. on the heating
surface of the thermal mat, since the heating system can burn
it and damage the mat. Bimetal switches work to protect the
mat with a body on it, or if the entire heating surface is covered
uniformly and only with porous layers. Emergency protection
system may not stop local overheat if it takes place only on a
small part of the mat, where there are no temperature sensors or
bimetal switches.

Your mat set should include, free of charge, at least one protective
cover, but usually we include a pair of dierent items. So you may
have one or two of the following covers:
1. Thick Tan 3-D Air Mesh Pad to cushion the mat, distribute body
weight, buer the crystals’ pressure either while sleeping on the mat
or during longer sessions. This is especially eective at the beginning
if the mat’s hardness is an issue. This 3-D Pad is not waterproof, and
it needs a cover or a towel on top. This Pad is recommended to be
hand washed and air dried to keep shape.
2. Thick High Absorption Waterproof Quilted Multilayer Protector
with a single MediCrystal® logo embroidery on the top and zipper
along three sides to put the mat inside of and to protect the bottom
as well. As with the other covers, it is permeable for FIR rays, PEMF
and ions. It is great for absorbing sweat and for keeping the contact
surfaces between the body and the mat dry. This pillow case style
protector is machine washable on gentle or hand wash cycle. Air
drying is recommended.
3. Thick Multilayer Protective Cover with multiple MediCrystal®
logo on the top and built-in thin 3-D Air Mesh Pad permeable
for FIR rays, ions. It also keeps the contact surfaces between the
body and the mat dry. This protector is used for cushioning the mat,
distributing body weight, and buering the crystals’ pressure either
SAFETY INSTRUCTIONS
while sleeping on the mat or for long sessions. These covers with
100% bamboo top air layers are not washable. Instead of washing,
we recommend leaving the mat with the pad on it for one hour every
week on the highest heat setting to keep both of them clean and
disinfected. Newer generation covers have top perforated air layer
with small addition of polyester and are hand washable. This cover is
xed on the mat with an elastic skirt.
4. Thin Waterproof Cover with 4-cornered elastic straps, to be used
on top of the 3-D Pad Protector or on top of the mat directly. Great for
short and high intensive sessions.
This thin cover is machine
washable and dryer-friendly.
Gentle cycle is recommended.
We hope that our protectors help
you feel more comfortable during
the sessions.
If the cover you want is not included
in the set, it may be purchased
from MediCrystal®.

through a surge protector, AVR or UPS device similar to that
one which protects computers or refrigerators. It will protect the
controller from any malfunctions resulting from a power surge.
Please remember to turn the controller OFF and unplug the mat
from the power socket aer use.
7. The rst heating of the mat should be to test the mat at the
highest temperature level (70 °C equal to 158 °F) for 2-3 hours.
This will also help purge any possible odors from the fabric and
other layers’ remaining volatile particles. If you are oversensitive
to smells you may choose to air it out in a garage overnight. Our
CONTRAINDICATIONS*
The following may not be a full list of contraindications but if you
have any of them, avoid use of the far infrared mat in heating mode
or for PEMF completely (unless you get approval from your doctor).
Remember that it is your responsibility to seek the attention of a
health care professional before and during the use of this product,
which is not marketed as a medical device, nor claimed to be able
to heal or cure any sickness.
1. The recipients of any type of organ transplant should not use FIR
or PEMF mats. Aer organ transplant operations, patients usually
are prescribed immunosuppressant drugs to help prevent their
immune system from rejecting the transplanted organs. FIR and
PEMF therapies increase immune system function which is absolutely
contraindicated for organ transplant recipients.*
2. Pacemakers and debrillators users should not use the FIR or PEMF
mats in powered modes without cardiologist approval. The function
of these devices may be interfered with by the mats’ magnetic or
heating functions.*
3. Expectant women should not use the heating function or FIR mat
in heating mode. Excessive temperatures have a potential for fetal
damage. If pregnancy is possible you should be able to sleep on the
mat or use it in unpowered mode for ion function but be sure to
consult a physician before using it with heating or PEMF.*
4. Newborns and infants should not use the heat or magnetic function.
Their core body temperature rises much faster than that of adults.
This occurs due to a higher metabolic rate per body mass, limited
circulatory adaptation to increased cardiac demands, and the
inability to regulate body temperature by sweating as well as adults
are able to. Do not use your mat in heating modes on babies who
cannot move away from the mat or on children who cannot speak
enough well to express themselves.*
5. Avoid use of the far infrared mat in heating mode completely (unless
you get approval from your doctor) in the case of a recent stroke,
aortic stenosis, myocardial infarction, heart attack, unstable angina
pectoris, if you take corticosteroids or have brain or other tumors.*
6. Anybody with diseases associated with a reduced ability to sweat or
insensitivity to heat should use the FIR Mat without the heat, in negative
ions or PEMF mode. Diabetic neuropathy may be a contraindication
because some diabetic patients lose sensitivity to heat.*
7. Nobody with diagnosed diseases, ailments or medical conditions
should ever use FIR devices without approval from and/or supervision
of a physician. It may be extremely dangerous to raise the body
temperature to high levels for people with: Adrenal suppression
disorders, Addison’s disease, adrenal Insuciency, systematic lupus
erythematous, multiple sclerosis (MS), brain tumors, bypass surgery,
high hypertension or some other conditions.*
8. Anybody taking medications or currently going under medical
treatments, radiation or chemotherapy should consult a physician
before using the mat in heating mode. Some medicines as diuretics,
barbiturates, and beta-blockers may impair the body’s natural
heat loss mechanisms. Some over the counter drugs such as
antihistamines, blood thinners may also cause the body to be more
prone to heat stroke. Sleeping aids, pain killers, narcotics, anti-
psychotic medicines may be the most dangerous in impairing one’s
judgement. People under inuence of drugs, alcohol or intoxication
as well as patients with mental impairments or dementia should
never use the mat, saunas or other heating devices.*
9. Anybody experiencing a high fever should not use the mat in heating
mode. Only the negative ions function can be used until the fever stops.*
10. If you use heating creams or balms, liniments, salves or ointments
that contain heatproducing ingredients, you should never use them
with the mat unless recommended by a health care professional so
as to avoid burns.*
11. Anybody with fresh wounds, trauma, joint injuries or swollen hot
joints where the cold practice is necessary should not use the FIR mat
in heating mode, so as to avoid exacerbating any inammation.*
12. Anyone with a mental or physical disability or those with limited
mobility should use MediCrystal® mats in the negative-ions-only
mode unless under full supervision of a medical professional and
have a doctor’s approval.*
13. It is not recommended to use any part of the heating area of your
mat directly on your head. Our brains do not have same ecient
cooling system as the other body does. Use a pillow as a barrier
between your head and the mat if you plan to sleep on it. The special
MediCrystal® Pillow with crystals is strongly recommended to keep
your head elevated and cool.*
14. Stop using the mat if any known conditions worsen while using
it. Pain should not be experienced when using the mat. However,
the infrared heat will go to areas of disease or discomfort – some
people may perceive this as pain and others as a sensation. If pain is
persistent, discontinue use.*
15. The use of a PEMF product is contraindicated in people with
pacemakers or other electronic implants, cochlear implants or
mechanical heart valves. It is contraindicated during pregnancy, and
in people with epilepsy or bleeding as well as for: organ transplant
recipients or those on immunosuppressive function, and those with
non-MRI safe Intrauterine Contraceptive Devices (IUDs).
While the above are some of the conditions which may pose dangers
through FIR Mat use, denitely check with your doctor or a health
professional experienced in PEMF, and Far Infrared or sauna about your
specic medical condition.
Remember that it is very important to properly hydrate with pure
and mineralized water before and aer sessions with the mat.
TIPS: BEFORE YOU START
1. Please study the Catalog and User Guide included with the mat
before rst use. The mat is easy to operate but the User Guide has
important safety information and a lot of dierent useful tips that
may help you get more benets and accelerate the learning curve.
Be sure to completely study the list of contraindications and
discuss them with a health professional.
2. Subscribe to MediCrystal® on youtube for educational videos. Our
youtube channel is https://www.youtube.com/MediCrystal
3. Consult your doctor how to use, especially it is important if
you have any chronic disease. Even if your health professional is
not familiar with hot crystal practices, doctors usually can give
good advice about how such or similar well-known technologies
like sauna or heating pads will work, especially in the case of any
existing health condition.
4. When you get the box with your mat, if it is too cold or too hot or
wet outside, please, keep the mat inside for an hour to adjust
to room temperature and humidity before connecting to the power
socket. Open the box and take out the mat carefully, especially if it
is a large size mat. It may be too heavy and you may need someone’s
help. Check that all accessories are included. Put the mat on the
oor, bed or other at surface with the crystals side facing up.
5. Our mats have special layers in the bottom that reect the heat
upwards. But if you use your mat on a hardwood oor or on
a memory foam mattress, it may be better to put a towel
under the mat to dissipate any remaining heat. If you have the
MediCrystal® pillow case type of protector it may be enough.
6. If your area is subject to frequent electrical blackouts or power
spikes, it could be better to connect the device to electricity

TIPS: USING YOUR MAT OR BELT
mats are made from the highest quality, ‘zero-emission’ materials
but it is still better to do this. Do not put the protector on the mat
or lay on it during this time.
8. Find a secure, dedicated area with calm surrounding and good
time to use your mat with some degree of concentration. Put up
“do not disturb signs” and play some soothing music to enhance
your experience. Put on comfortable sleepwear and relax. It may be
a good idea to clean and scrub your body to open the pores before
your sessions, as this will facilitate sweating and detoxication.
1. It usually takes around 30-60 minutes for the Mat to reach the
maximum temperature if you put both a thick protector and a
thick blanket on top. Cover the mat with a blanket and leave it
periodically, checking how hot it is under the blanket.
2. The heating process stops and resumes again when the mat
cools down, to maintain the set temperature. During this time,
the gems become very warm and emit radiant Far Infra-Red rays.
3. For extra electrical safety the heating wires are positioned a short
distance from the mat’s edges so that the end tubes with crystals
are heated indirectly by other stones. It is normal when these close
to edges of the mat stones have a lower temperature.
4. When the heat is on, the surface temperature of the bare mat under
the blanket, or under your body if you are on the mat, becomes hot to
touch. At maximum heat level it will reach 140-150 °F (60-65 °C)
on the surface, if measured immediately aer you stand up or
remove the thick blanket or pillow. But if you measure the bare
mat surface temperature in several minutes again it will be much
lower, around 110-130 °F (40-50 °C). If the mat is uncovered, and
room temperature is low or the air ow is strong, it will cool the mat
very quickly. This is normal – when preheated, the crystals transfer
most of the energy in the form of Far Infrared Rays very quickly.
5. If you keep your mat open without the protector pad, blanket, or your
body on it, the heat is dissipated – and though the controller may continue
to show rather high temperature inside the mat’s heating elements, the
surface will be merely warm to touch even on highest level.
6. Sometimes when the mat starts to heat some humming or buzz
noise can be heard from the controller which is quite normal. But
if the noise gets stronger or you feel any smell or other signs
of possible controller or mat failure, please stop using the mat.
7. It is OK for the controller to warm up a little when the mat is on the
highest heat level or if several functions are activated all together
for a long time. But it is not normal if the controller gets really
hot or if you notice any smell. Please turn o the mat and contact
us for a free replacement if this happens. Remember not to put
controller on the mat, even if the mat is cool. It may heat up
and damage the controller.
8. The most frequent reason for initial controller malfunction is an
incorrect order of connection. It is necessary to connect the mat
to the controller rst, TIGHTLY, and only aer this should you
plug the controller into the outlet, then turn it on and set the
timer. Aer this you may choose the heating mode, set desired
temperature, and/or activate Red Light and PEMF functions. When
you disconnect, rst turn the controller to OFF, then disconnect
the plug from the socket – and only aer this (and only if it is
necessary), unplug the controller from the mat.
9. Do not disconnect the controller from the mat more frequently
than necessary, in order to avoid the connection becoming
loose. If you connect the controller to the power source rst
(before connecting it to the mat), the safety program will lock
the controller and put it in ‘safe’ mode. It may start to beep or
will show OF or other error code on the screen. To reactivate the
controller simply reconnect it in the correct order.
10. Choose the best position. FIR amethyst rays penetrate deep and may
awake resonant vibrations on micro level so that even aer the session
is over the body temperature may stay elevated to normal level of
98.6 °F for up to 8 hours, which is good for activity and rejuvenation.
This phenomenon is described in the European bestseller «98,6 –
Ideal Body Temperature as the Secret to Optimum Health» by famous
German naturopath Dr Uwe. But there is also the local eect when
those organs and tissues which are closest to the mat receive more
heat. It may be benecial for them, but the highest levels may also
cause some issues with movement if you have stones, etc. If you lay
on your right side, please be sure that you do not have gallstones
in the bladder and that it is healthy. Heat may cause gallstone
movements and cause inammation and pain. If you lay on the mat on
your belly, it is important to protect your genitals. The le side is safer
in this regard, but usually laying on one’s back is the best position.*
11. If the mat feels hard at the starting point, it is essential to
cushion it and eliminate the crystals’ pressure correctly. Put on
top a 3-D pad, and a cover included into the set of your mat. You
can add several layers of bamboo, cotton sheets or towels, but not
more than one inch thick to make your mat even soer. As soon
as your body gets used to the crystals’ pressure, you may choose
to remove the extra layers one-by-one. Protectors and towels are
great for sweat absorption during heating sessions or for moderate
cushioning, but for high intensity, it may be better to use your
mat without any covering. With FIR, some of the heating rays will
dissipate if you use a thicker layer on top of the stone mat and
under your body. The same applies to negative ions, but most will
still travel through. As for longer sessions, even with covers the
mat can still be too hard to sleep and too heavy to remove it from
your bed every evening (especially if you have a large size mat).
A simple solution is to put a 3-4 inch thick mattress pad on top,
which is lighter and easier to handle than the stone mat. Be aware
that you can cover your mat with a thicker than one-inch layer or a
non-permeable foam pad ONLY aer the mat cools down. To avoid
overheating and re risks NEVER heat your mat with the topper or
thick layer on it. Always remove the topper rst and leave only a
thin cover or a 3-D pad before you turn ON heating function.
12. Always keep your Waterproof Protector on the mat to protect it
from spills and dirt. But even if your mat occasionally gets wet, do
not worry, it has waterproof layers inside. Just let it completely dry
before using it again if it gets wet.
13. Be careful with your rst session. Use a slow and continuous
mode of increasing intensity. Begin with temperature levels as
low as 96–112 °F (35-45 °C) and short sessions, no more than a
half hour, and gradually increase the length and intensity for several
minutes and/or degrees every other day. Remember to drink a lot
of water, fresh juices, or herbal teas. Replenish minerals to avoid
becoming drained or dehydrated. When you start it is important to
avoid overuse, and low temperature burns and get the rst benets in
a safe manner without the risks of side eects from a “healing crisis”.

14. Most important is to listen to your body as you move forward –
“LOW and SLOW”. It is easy to overdo if you move ahead too quickly,
and the cumulative eects are much more desirable without the
lightheadedness or other side eects that can come with rapid
detoxication. The maximum time for each heat level is not specied.
It depends on the mat’s size, temperature level, and one’s age, health,
body size and composition, and many other factors. Basically, the
main rule is to start with low settings and gradually increase
the intensity, length and frequency of sessions. Of course if you
are an experienced FIR sauna user, you can start with the maximum
temperature level, or you can even use the sandwiched-between-
two-mats session, but we always recommend checking with your
doctor rst and using common sense to avoid overuse.
15. As soon as you are sure that your body reacts ne, you can use
your mat as long as you like. Unless you have special needs,
you can use it from a few times a week for 30 minutes to 12
hours daily and it should be an enjoyable process. If you want
an intensive sweating sauna-like detox, choose the maximum
temperature suitable for your health and cover your body with a
blanket or another mat. If you just want comfort, set the medium
heat levels at around 112–122 °F (45-50 °C). If you are just
starting out 20 minutes may be enough. Dierent people react
dierently and enjoy dierent modes. Some folks with weakness
caused by hypothermia use FIR mats all the time on slightly warm
temperature to revive and feel well again. Other people use
amethyst heating mats from one hour on high temperature to 12
hours on warm temperature. Be sure that sessions are comfortable
for you and bring about a better feeling and more energy, and of
course remember to get approval from a health professional.
16. If you accelerate this way, the rst aim is to create a feeling of
relaxation. To relax, you may have a short session before bedtime
of about half an hour, starting at 40-50 °C, and then decreasing to
the lowest levels of 30-40 °C. If these levels cause any lightheaded
feeling or overstimulation, the temperature should be set even lower
or even the mat should be used in unpowered mode. Especially in the
summer, when it can absorb some excess heat from your body and
naturally return it in the form of radiant crystal rays to those parts of
your body which need more warmth.*
17. The second target usually is to cause sweating, which is great
for detoxifying the body. All intensive high heat sessions should
be done with proper rehydration and electrolyte replenishment,
and within the rst half of the day. It may take up to an hour to
preheat the mat under a thick blanket to a high heat level. Then you
can lay on your back on a bare mat, or a mat with a thin protector
or a towel on it and cover yourself with a blanket. Aer the session,
just leave the bare mat for half hour more while still heating to dry
it out. Of course if your body does not sweat much, you may not
start to sweat from the rst session – but aer several it should
come. Drink a lot of hot herbal teas (not cold drinks) before and
during the session to accelerate sweating. When your body gets used
to sweating it will be easier to sweat voluntarily.*
so it should not be adversely aected by infrared rays. Please,
consult your surgeon and implants manufacturer prior to use of
heat directly on implants areas.*
4. Heating of the low back or low abdomen areas of a woman’s body
during the menstrual period may temporarily increase their menstrual
discharge. Some women endure this process to gain the pain
relief commonly associated with their cycle, whereas others simply
choose to avoid using the product during that time of the month.*
5. It is reasonable not to use any heating pad on your groin area,
face, head and all other areas sensitive to heat. If contraception
is not your aim, do not apply heat to your genitals. You can use
a cooling pad or make a non-permeable for FIR rays screen with a
towel folded many times and covered with several layers of standard
aluminum foil. It helps for short sessions.*
6. Children may use mats or other items with caution and under
supervision of adults, preferably on low heat or negative ions mode
only. Consult with the child’s pediatrician before using the FIR pads
and use common sense. Do not leave children or toddlers on the mat,
or with the belt, wraps or other hot stone pad without supervision.
They can walk, play or jump on the pad with crystals and damage inner
sensors. Children can disconnect cables and put them into their mouths
and get shocked. Take extra care if your child has access to the room
where the belt or hands wrap or any other electrical device is located.*
7. If you use medicines applied by skin patches, you should
denitely consult your doctor. The absorption rate of a
transdermal medication can change. If you use an adhesive, it
may also unglue from your skin due to sweating.*
8. Cats and dogs love amethyst and gemstone pads. They feel some
energies better than humans. We suggest to have an additional
waterproof cover for the pad to protect it from any liquid
and make sure your pet will not chew or scratch the cable,
controller or pad. We recommend cheaper and safe non-
powered, non-electric amethyst or gemstone mats for pets.
Consult with a veterinarian prior to use mats, pads, belt or wraps
for heating. Be careful with pets sleeping on the device. It should
always be turned o without supervision.*
9. You should always drink A LOT before the session, during the
session and aer the session – if you feel dry mouth it means
that there is not enough water in the body. And it should not
be just water, you may need to replenish some electrolytes and
minerals as Ca, K, Mg, Na. Twitching may be a sign of these salts’
serious decit or imbalance so if you sweat a lot herbal teas, fruit
juices, and mineral water rich in K and Mg or mineral supplements
may be necessary. Proper hydration also promotes all eects
improving detoxication caused by sweating.*
10. Overusing the product on maximum temperature may result
in excessive stimulation. Use moderately on high temperature.
Even if your product can heat in a continuous mode, it is strongly
recommended not to use the high heat settings for more than 3 hours
for your safety! Some temporary symptoms of organism detoxication
(“healing crisis”) may occur especially if you start too fast.*
11. Detoxication high heat program should not be done without a
doctor’s approval and supervision. Some drugs, chemicals, and
toxins which we take into our bodies with air or food end up getting
stored in our fat tissue. They can aect you as you mobilize them
and sweat them out. Before toxins are excreted and exit through
the sweat pores they are absorbed from your decomposed by FIR
heat fat tissues into the bloodstream. While traveling on their way
to be eliminated, substances can exert the same eects that they
do when you had originally taken them. If a lot of residue was
accumulated in your fat tissue and their release is too fast, the
buildup of these poisons can make you feel worse. That is what
is called detoxication or a “healing crisis”. If you are chemically
allergic or extra sensitive, the dangers of infrared function,
regarding the release of toxins, may be serious. If you feel any signs
of “healing crisis”, stop using the product and consult your doctor
as the same symptoms may be also the signs of serious illness.
12. William Rea, MD, one of the most knowledgeable doctors in the
world regarding environmental toxicity and sauna detoxication,
warns: “Uncontrolled, too-rapid mobilization can have
devastating eects on chemically sensitive patients.” Of course
it does not mean that chemically sensitive people cannot get rid
of toxins. Just that it should be done very slowly and carefully, and
with a doctor’s supervised detox program. Slowly and gradually
increasing heat level, session length, and frequency is the
best path forward and It is important to immediately decrease
intensity, duration and frequency of sessions and contact your
health professional if you feel symptoms of a “healing crisis”.*
13. The most important thing when you start to use the mat is to avoid
acupressure overstimulation and overheating. If you would like to
sleep on your mat, do it slowly, adapting your body to the pressure.
You can start with shorter sessions at bedtime with 3-D Pad and extra
cushioning layers and move forward gradually. It is like acupuncture –
there’s no need to overstimulate the body from the outset, it is better
to increase the intensity of pressure slowly and continuously.
14. Very careful approach is appropriate to FIR heat function. Our
skin sensors can easily detect the high temperature caused by
standard conduction heat, but our ability to feel the eects
of radiant infrared heat is limited. The FIR warmth is much
more penetrating, so the hot stone pads should be used on much
lower sensible temperature than a standard heating pad, and it
demands extra care, especially for long or all-night use.
15. Minor reactions to low intensity PEMF sessions may occur in some
individuals. Because PEMF practices result in many activities,
some people especially with lots of toxins accumulated or just
oversensitive to magnetic elds may experience slight discomfort,
especially when using it for the rst times. Lower frequencies
from 1 to 10 Hz and shorter 10-15 min sessions are least likely to
cause any negative reaction and are optimal to create a restful and
balanced environment for relaxation and general well-being.
Use common sense, self-educate, listen to your body and we hope
you experience as many positive results as we have, now that you
have your own MediCrystal® Mat, Belt, Pad or Wraps.

TIPS: USE WITH CAUTION*
18. For FIR Heating, if you lay bare on the bare mat with your
body covered with a thick blanket, you will get the maximum
“detox” eect, as no heat will be lost or dissipated. All crystal
rays will be radiated into your body. Some advanced customers
even use foil blankets reecting FIR Rays back to the body, but
it is very intensive function and it cannot be recommended
without a doctor’s approval. Sweat releases a lot of toxins, and
FIR releases even those stored in deep fat tissue, into the blood. It
may be irritating and erosive to the surface of the mat. That is why
something like a sheet or a protector cover under your body is must-
have for everybody. Perspiration may also temporarily make you feel
worse, but when the sweat is out you should feel refreshed.*
19. For the rst time you can try the PEMF, on the lowest heating
levels, for 20-30 minutes to check how your body reacts. Later
if necessary you will be able to use all the functions or any of their
combinations together. However, for some folks it is better not to
use PEMF on high heat to avoid overstimulating. Regarding PEMF
function use in the daytime, there are many schemes – the standard
is a simple half-hour session (it will auto-o aer 30 minutes). Or
you may choose to cycle it. If you have dierent frequency controller
you may try dierent ways to use to nd what works for you the best.
20. Wearing clothes or using covers or sheets on the mat hinders some of
the anion eects, but it should not be an obstacle to PEMF or FIR Heat.
21. If you are falling asleep while on mat, turn OFF PEMF function (so that
it does not wake you up when aer it resumes in 4 hours or if PEMF
is programmed for auto cycling). But most importantly, choose 30-
45 °C or 86-110 °F low level of FIR Heat before going to bed.*
22. Getting a headache or feeling dizzy is a sign of “healing crisis”
(dehydration). It means that you are detoxing too fast. Lower the
temperature, drink more water and stay on the mat for shorter
time. It is important to feel comfortable and enjoy your experience,
so listen to your body and adjust intensity and duration accordingly.
If your mat is equipped with adjustable frequency controller, it
is suggested to start PEMF at a low frequency such as 4 Hz then
increase to 8, 10 or 14 Hz. Usually lower frequencies have more
calming eects while higher frequencies provide more stimulation
and promote activity. If you use a standard controller try PEMF on 10
Hz for 5-10 minutes for the rst time. PEMF side-eects are usually
either non-existent, or very minor and temporary but they may be
observed in users who are hyper sensitive to electromagnetic elds.
Usually changing the frequencies or limiting session time will help
to resolve any issues. Of course if you have any contraindications,
you can use your mat without activating the PEMF function at all.
23. MediCrystal® mats with bio-magnetic function have copper coils
inside and are designed to be used at on your bed, massage table
or sofa. Only the special Chair Mat can be used both in horizontal
position and for sitting in your chair, recliner or on the sofa. If
you need to wrap your body only the exible MediCrystal® pads
and blankets without PEMF function can be bent. Please, check
MediCrystal® catalog for more details.
1. Extra care is necessary if you are diagnosed with diabetes. If
patient has a lot of sugar in the blood, it clots the blood vessels
and causes nerve disorders. Some people with diabetes can, over
time, develop nerve damage throughout the body. It is called
diabetic neuropathy. If you have diabetic neuropathy and loss of
sensitivity you should use a strict time/frequency/temperature
protocol established by your doctor, and only under supervision.
You should start very slowly and monitor your blood sugar.*
2. Titanium pins, rods, articial joints or any other modern surgical
implants usually reect FIR rays so they should be generally safe.
But some joint replacements and piercings with other metals may
be warmed by infrared rays. So safety precautions should be
taken if you lay with joint replacements in direct contact with
the mat. If you lay on your back and knee or hip replacements
are above the mat, there should not be a problem. But of course
if you feel any discomfort in the implants area, it would be
better to decrease the temperature and session length or to
turn the mat OFF. It is also advised that you consult your surgeon
and implant manufacturer.*
3. Silicon implants may be warmed by infrared rays, so safety
precautions should be taken if you lay with implants in direct
contact with the heating pad. If one has breast implants but
lays face-up, there should not be a problem. Usually silicon used
in medical implants is known to melt at over 200 °C (392 °F),
TIPS: TROUBLESHOOTING
1. Ensure the electrical wall socket that you’ve plugged the
apparatus into is working correctly. Plug another device into it
to ensure it has power. If it is not working, consider checking the
electrical panel as a breaker may have popped (or broken) and
needs to be reset. Or try another electrical wall socket that you
have veried is powering other devices. If you are using a surge
protector, ensure it is working properly. Plug another electrical
device into and verify that it is working.
2. Ensure the controller’s plug is pushed all the way in to the
belt’s receptacle socket so that it is snug tight with no space
at all between the plug and the mat’s (belt’s or pad’s) or hands
wrap’s socket. A loose connection can cause loss of signal exchange
between the mat with crystals and the controller, and when too many
errors accumulate the controller’s calibration may fail. Controller
will show error messages or the apparatus will not heat up properly.
3. Make sure that the power button on the controller has been
turned ON. The controller may show OFF on display. It means
that either preset heating time is over or the connection between
controller and belt or hands wrap is lost. Try adding time,
powering the controller ON/OFF, or reconnecting it.

4. Please activate the timer button and choose one of the timer settings
to start heating. Some models of the controllers do not activate
heating function unless a timer is set.
5. Frequent reason for the new controller fault and errors is an
incorrect order of controller connection. Please, rst connect
the pad, mat, belt or wraps to the controller, and only aer
this plug the controller into an electrical outlet and turn
the controller ON. When you disconnect, rst turn it OFF, then
disconnect the plug from the socket, and only aer this unplug the
controller from the apparatus. If you connect the controller to
the power source rst, the safety program may lock it and go
into safe mode. It may start to beep or will show OF or OP error
on the screen. The same may happen if there is a loss of signal
interchange between the belt or hands wrap and the controller. To
reset it just reconnect it in the correct order.
6. If controller shows errors, the easiest way to solve the
problem is to reset it. Disconnect the plug from the socket
rst and then from the belt or hands wrap connection terminal.
When you disconnect the plug from the appliance, please always
do it carefully with two hands, holding the connector with one
hand while the other hand pulls the plug. Pull the plug out of the
connector on the device carefully as well. Do not pull it by the
cable or the connection between the hot stone mat terminal
and the controller plug may become loose. Aer this always rst
reconnect the controller to the mat tightly and then plug it into
an electrical outlet again. Be sure that the socket has electrical
power, this can be tested by using any other electrical device.
Reconnection and reset are the most common ways to
eliminate errors and reload the controller.
But if reconnection or any other way of troubleshooting do not
improve the situation, it likely means that there is a problem with
the controller. If your controller was not accidentally damaged or
ooded we will replace it ASAP, fast and free.

7. Do not worry if your mat or pad are not hot to touch. All FIR
Amethyst mats do not work like conventional heating pads. Most of
the energy from the hot stone mat, pad, belt or wraps in the form
of Far Infrared Rays heat, is transferred by radiation, and not by
conduction (as is the case with standard heating pads, which are
hotter to the touch but do not heat the body much). If the hot stone
mat is le uncovered, it should be slightly warm on lower levels, warm
on medium levels and very warm on high levels – but the transferred
heating energy is actually much higher, and this warmth is far more
penetrating. So the hot stone pads of any size from the small belts or
wraps up to Single or Queen mats should be used on a much lower,
more prudent temperature than a standard electrical heating device –
and it demands extra care, especially for all night use.
8. It usually takes around 30-60 minutes for the pad to reach the
maximum temperature if you put both a thick protector and a
thick blanket on top. The heating stops and resumes again when
the pad cools down, to maintain the set temperature. During this
time, the gems become very warm and emit radiant Far Infrared
rays. For extra electrical safety the heating wires are positioned
a short distance from the belt’s edges so that the end tubes with
crystals are heated indirectly by other stones (these stones may
have a lower temperature). The surface temperature of the bare
pad under the blanket, or under your body if you are on the mat
or pad, becomes hot to the touch, especially in those areas which
are covered by lm or mesh. At maximum heat level It will reach
140-150 °F on the surface, if measured immediately aer
you stand up or remove the thick blanket. But if you measure
the bare belt or hands wrap surface temperature in several
minutes again it will be much lower, around 110-130 °F. If
the pad with crystals is uncovered, and room temperature is low
or the air ow is strong, it will cool down very quickly. This is
normal – when preheated, the crystals transfer most of the energy
in the form of Far Infrared Rays. Hot stones radiate heat very
quickly. If you keep your mat, belt, wraps or any other hot stone
pad open without the protector pad, blanket, or your body on it,
the heat is dissipated – and though the controller may continue
to show rather high temperature inside the heating elements, the
surface will be merely warm to touch even on highest level.
MAINTENANCE AND CLEANING
WARRANTY
TIPS: TAKING CARE OF YOUR MAT OR BELT
1. The mat should not be used outside if you are not sure about
weather. Use it indoors on at surface as massage table, bed,
sofa, mattress or oor. It’s ok if the surface is not ideally hard
and at as board.
2. Only the exible MediCrystal® pads and blankets can be bent to
wrap your body or used on chair or recliner while heating. Bio-
Magnetic Amethyst Tourmaline MediCrystal® V-mats have PEMF coils
and cannot be used in bent condition. Only a special Bio-Magnetic
V-Mat for chair can be used both to lay on and while sitting. Another
option is the Amethyst Tourmaline Belt with detachable 8 by 18 inch
heating pad which is small, light and portable and may be the best to
focus on lower back or any other specic area you need.
3. Sometimes controllers and even devices issues happen aer power
spikes. When hurricanes or storms are approaching, if you are not
going to use your hot stone pad for a while, or if you are leaving
your home for a weekend or vacation it is better to unplug it from
the socket. The best is to keep your pad unplugged from the
power socket always while it is not in use.
4. No need to unplug the controller connector from the pad
connection terminal frequently. If the controller always remains
connected to the pad it is OK as this only helps prevent
the connection from loosening. Just remember to verify the
tightness of the connections from time to time, especially if you
sleep on your hot stone mat. If you have to disconnect the plug of
the controller from the pad’s connection terminal always do this
carefully and with both hands. Hold the connector with one hand
while pulling the plug carefully with the other hand. If pulled
by the wire it can break, or the connection may eventually
become loose and the pad will not work correctly.
5. Please take care of your hot stone mat, pad, belt or wrap and it will
be your friend for a long time. It is great for meditation, sleeping,
and sessions, if laying calm on it without a lot of movement.
Never apply pressure or step on it. Dogs and especially cats adore
it and can use but this should be under your supervision. Do not
allow heavy dogs to play in the same room. Children like to jump
but it may be very harmful if they jump on the pad. There are
a lot of tiny electronic parts inside such as bimetal switches,
temperature sensors, etc. Occasional acute pressure may damage
them. In order not to damage the inner sensors and heating
system electronics avoid impact, walking, standing, training,
doing any active exercise on the pad. Do not allow any heavy
or sharp objects to be put on or fall on it. Never fold it while
hot, never heat it in folded condition.
6. Most MediCrystal® mats come folded with the top surface with
crystals upside. But some models of MediCrystal® mats come
folded with crystals inward. Please, always fold the mat for
storage, same as it was folded when you received it. If the mat is
folded in the wrong direction, it may be damaged. Do not fold
it too tightly and never put heavy objects on it.
7. Do not store the mat vertically along the wall. Store the device in
the bag provided. Consider storing the controller and plug separately
so that the sharp edge of the power socket plug does not damage the
mat’s so leather or suede. Do not store the device in a humid, dusty
or oily place. Store it in a clean ventilated storage room or closet.
You will not have to clean your mat, pad, belt, vest or wraps at all If you
cover it with our MediCrystal® Waterproof Cover, or at least a cotton or
bamboo towel all the time.
It will stay clean for a very long time unless you use it uncovered or
spill something on it.
1. Before cleaning, turn o the mat using the button on the controller
and then unplug the device from its power source.
2. Do not use chemical solvents such as benzene or thinner or
aggressive cleaning agents on the controllers and pads with crystals
because it may damage them.
3. Clean it as you would clean any leather or suede product that has
electrical parts inside. Do not wash the mat or controller with water.
Do not put them in a washing machine or dryer.
4. Do not get the mat with crystals wet. But even if occasionally you
spilled something and the mat was not covered with a waterproof
protector, do not worry, it has waterproof layers inside. Just let it
completely dry before using it again. Then test it on high heat for an
hour before laying your body on the belt or hands wrap. Remember
that ironing the device is strictly prohibited.
5. Use only a slightly wet cloth (soap water can be a good choice) to
wipe o dirt and dust. You could also use a vacuum to remove any
dust from the surface of the mat.
6. You may leave your belt or hands wrap with protectors on high heat
for 1 hour each week to completely self-clean and disinfect.
7. To fold the mat of any size including the amethyst micro-mattress
or belt attachment pad and wraps, disconnect the power plug from
the socket, then from the mat, belt or wraps. Aer this fold the mat,
belt or wraps inward. Try not to bend rm mat and belt in unusual
places. Your mat and belt will last longer the less you fold or bend
it. Wraps are more exible and withstand bending better, but extra
care is always necessary while folding it. Try to fold in the same
manner as the item was received.

If your mat is rated for the North American 110-120V voltage and your controller is with the U.S. standard NEMA 5-15P (two-pole with
ground pin) plug, use it only with the step-down 220-250V to 110V voltage converter in the 220-250V 50Hz countries. The maximum
wattage of such converter should be at least 2-3 times higher than the mat’s power consumption. Do not connect the 110-120V mat
into the 220-250V outlet through an adapter. If you plug in a device that isn’t rated for the outlet’s voltage, it may be severely damaged,
and cause re risks!
