We were so impressed by how the functionality of our mats
compared to other, much more expensive brands that we decided to
launch a business focused on creating these amazing products.
Our purpose is to let other people unveil the secret of this reviving
experience at a substantial savings from the competition. We think not
just the wealthy, but everyone interested in holistic, naturopathic and
alternative practices should be able to use the power of these gems
and crystals.
We hope you experience as many positive results as we have, now
that you have your own ThermoGem™ Mat!
UNBOXING
THE MAT SET INCLUDES:
When you receive the box, it may have wear due to shipping.
Please take a moment to carefully unpack the box and check if the
set includes everything in the due condition. If you discover that
anything is missing, or there is any other reason that you wouldn’t
rate this as a 5-star experience, please, contact us right away at
[email protected], so that we resolve the issue as fast as
possible.
In addition to hot stone functionality, and deep FIR heat, ThermoGem™
Flexible 3-gems Pad naturally generates negative ions through special
layers upon heat distortion when the mat is ON or using your own body
heat when the mat is OFF.
It is a great reason to use the pad as the mat to lay on and relax,
reenergize or sleep. But you can also use the exible pad as a blanket
to cover yourself while you are on the other mat.

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 also 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.
During bedtime an external timer can be used. Some heavy duty
ones with a built-in surge protector may be a good choice for double
protection.

1. The top of the mat, with the ThermoGem™ 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. ThermoGem™ mats have a multilayer system construction with up
to 16 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 crystals. 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.
3. 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.
4. 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.
5. 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.
6. Mini mat is great for localized use, when you need to apply
crystal rays and focus to some area of your body (back or legs
most frequently) without causing the whole body to undergo
hyperthermia. You can use it on high heat for local application
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 detox
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.
7. 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.
ADDITIONAL INFO COVERS
*MediCrystal® and ThermoGem™ products are not intended to diagnose, cure, treat, mitigate or prevent any disease, illness or medical condition or to substitute for medical treatment of any
kind. Information here is never to be construed as medical advice. These products and statements have not been evaluated by U.S. FDA (please, see Disclaimer in this user guide, page 11).
ThermoGem™ 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/60Hz for North America and Japan and
220-250V/50Hz 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/60Hz, 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. Clean the mat only when the power is o and the controller is
unplugged from the AC outlet.
12. 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.
13. 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
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
SAFETY INSTRUCTIONS
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®.
Please, check for more
information about covers
in the MediCrystal®
Catalog.

6. If your area is subject to frequent electrical blackouts or power
spikes, it could be better to connect the device to electricity
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
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
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 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 hot stone
therapies increase immune system function which is absolutely
contraindicated for organ transplant recipients.*
2. Pacemakers and debrillators users should not use the FIR 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 for heating.*
4. Newborns and infants should not use the heat 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 mode. Diabetic neuropathy may be a contraindication
because some diabetic patients lose sensitivity to heat.*
7. Nobody with diagnosed diseases, ailments or medical conditions
shouldever use FIR devices withoutapproval 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 ThermoGem™ 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 ThermoGem™ 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.*
If you have any of these conditions, avoid using the mat completely
unless under the care of a doctor with expertise in hot stone mat
or sauna detoxication.
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 Far Infrared or sauna practice 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
ThermoGem™ pillow case type of protector it may be enough.
*MediCrystal® and ThermoGem™ products are not intended to diagnose, cure, treat, mitigate or prevent any disease, illness or medical condition or to substitute for medical treatment of any
kind. Information here is never to be construed as medical advice. These products and statements have not been evaluated by U.S. FDA (please, see Disclaimer in this user guide, page 11).
TIPS: USING YOUR MAT
smells you may choose to air it out in a garage overnight. Our 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 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 set desired temperature. 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
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 the mat 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 mat and
use common sense. Do not leave children or toddlers on the mat
without supervision. They can walk, play or jump on the mat and
damage inner sensors. Children can disconnect cables from the
mat and put them into their mouths and get shocked. Take extra
care if your child has access to the room where the mat 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 mats. They feel
some energies better than humans. We suggest to have an
additional waterproof cover for the mat to protect it from
any liquid and make sure your pet will not chew or scratch
the cable, controller or pad. We recommend non-powered,
non-electric amethyst or gemstone mats for pets. Consult
with a veterinarian prior to use mat 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 device on maximum temperature may result
in excessive stimulation. Use moderately on high temperature.
Even if your mat 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
mat 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.The same careful approach is appropriate to 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 mat 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.
This especially refers to the larger sized mats, which are very
powerful. Please use such mat only on the lowest setting
while sleeping.
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 ThermoGem™ Mat.

TIPS: USE WITH CAUTION*
crystal rays to those parts of your body which need more soothing
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.*
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 practice 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.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 FIR Heat.
20. If you are falling asleep while on mat, choose 30-45 °C or
86-110 °F low level of FIR Heat before going to bed.*
21. 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.
22.Classic ThermoGem™ mats are designed to be used at on your
bed, massage table or sofa. Mini Mat (20x32”) can be bent up
to some degree to cover your body while heating. But the special
Chair Mat is a preferable choice for sitting practice in your chair,
recliner or on the sofa and only the exible ThermoGem™ pads
and blankets can be bent to wrap your body.
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 mat. 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), 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 mat during that time of
the month.*
5. It is reasonable to protect groin area, face, head and all other
areas sensitive to heat. If contraception is not your aim, and if
you lay on the mat on your belly, it is important to protect your
genitals. You can use a cooling pad or make a non-permeable for
TIPS: TROUBLESHOOTING
1. Ensure the electrical wall socket that you’ve plugged the mat
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 mat plug is pushed all the way in to
the mat’s receptacle socket so that it is snug tight with no
space at all between the plug and the mat’s socket. A loose
connection can cause loss of signal exchange between the
mat and the controller, and when too many errors accumulate
the controller’s calibration may fail. Controller will show error
messages or the mat 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 mat 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 for the mat to start heating. Some models of the
® ®

controllers do not activate the heating and other functions
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
mat 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 mat. 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 mat 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 mat connection terminal. When you disconnect the plug from
the mat, 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 mat carefully as well. Do not
pull it by the cable or the connection between the 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 is not hot to touch. The FIR
Amethyst Mat does not work like a conventional heating pad.
Most of the energy from the mat, 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 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 mat 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 Mat 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 mat 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 mat’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 mat under the blanket, or under your body if you
are on the mat, 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 mat surface temperature in
several minutes again it will be much lower, around 110-130
°F. 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. Hot stones radiate heat very quickly.
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.

TIPS: TAKING CARE OF YOUR MAT
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 ThermoGem™ pads and blankets can be bent
to wrap your body or used on chair or recliner while heating.
Mini Mat (20x32”) can also be bent up to some degree to cover
your body while heating. But special Chair Mat is a preferable
choice for sitting practice in your chair or on the sofa.
3. Sometimes controllers and even mat issues happen aer power
spikes. When hurricanes or storms are approaching, if you are
not going to use your mat for a while, or if you are leaving your
home for a weekend or vacation it is better to unplug the mat
from the socket. The best is to keep the mat unplugged from the
power socket always while it is not in use.
4. No need to unplug the controller connector from the mat
connection terminal frequently. If the controller always remains
connected to the mat 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 mat. If you have to disconnect the plug of
the controller from the mat 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 mat will not work correctly.
5. Please take care of your mat and it will be your friend for a long
time. The mat is great for meditation, sleeping, massage and
healing sessions., if laying calm on it without a lot of movement.
Never apply pressure or step on it. Dogs and especially cats adore
the mat and can use it 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 mat. There
are a lot of tiny electronic parts inside the mat 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 mat. Do not allow
any heavy or sharp objects to be put on or fall on it. Never
fold the mat while hot, never heat it in folded condition.
6. Most ThermoGem™ mats come folded with the top surface with
crystals upside. But some models of ThermoGem™ 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.

minimum cost.
Whether the problem is with the product itself or the controller, we will
provide you with a replacement as soon as possible.
Shipping and return shipping are both free for warranty issues.
You can also buy a 4-year extended home use warranty or 2 years
professional use warranty. It costs 50% of the item cost.

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!
