GB 2. MEDICAL BACKGROUND
WHAT IS TENS?
TENS = Transcutaneous Electrical Nerve Stimulation. TENS is an effective method offering Pain
Relief. TENS utilises the nervous system’s own pain relief mechanisms to ease both acute and
chronic pain.
WHEN IS TENS USED?
Good results are observed in acute and long-term pain conditions of many kinds, but above all
when the pain originates in joints, the skeleton, muscles, skin, viscera, or nervous system. In
some cases, TENS on its own may be sufficient, and in other cases it may provide a valuable
complement to other forms of treatment.
HOW DOES IT WORK?
With the Pain Relief programs, impulses are sent through the nerves to block the pain impuls-
es. Pain Relief is usually most efficient during stimulation, but the effect can also last after the
program has finished. It also increases the circulation. The Massage programs increase the cir-
culation and decrease the tension in the muscles.
The Pain Relief programs do not always treat the cause of pain. If the pain persists, seek medi-
cal advice.
WHEN SHOULD I USE TENS?
The programs in the CEFAR EASY can be used on any occasion when Pain Relief or Muscle Re-
laxation is needed. All the programs can be used as often as required. Every session should last
at least a minimum of 30 minutes up to several hours.

GB 6. REPLACEMENT OF BATTERIES
When you see the battery symbol in the display, it means that the batteries very soon will
run out. As long as stimulation feels the same as usual you can continue the treatment. It
is time to replace the batteries when stimulation starts diminishing or the stimulator stops
working.
• Switch off the stimulator.
• Remove the battery cover,
take out the batteries.
• Make sure that the new batteries are placed
correctly with respect to the
polarity (+ and - symbols). See picture.
• Dispose the used old batteries at
a recycling station.
Rechargeable batteries should be charged when the indicator lights up or the
stimulator stops working. NOTE! Never try charging non-rechargeable batteries, due to the
risk of explosion.
If the CEFAR EASY is not used for some time (approximately 3 months), the non re-chargeable
batteries should be removed from the stimulator.

GB
7. CARE INSTRUCTIONS
Taking care of and cleaning the CEFAR EASY equipment is simple, provided the following
instructions are observed:
• Keep stimulator and accessories in the
original case when they are not in use. It
may, however, be practical to allow the
electrodes to remain on the body between
treatments. Carbon rubber electrodes can
generally remain for 2–3 hours without the
electrode gel drying out (does not apply to
adhesive gel). They must then be taken off,
washed, and dried before being applied
again. This is especially important for per-
sons with sensitive skin. In connection
with stimulation, make sure that the elec-
trodes are firmly in place.
• When using carbon rubber electrodes, use
plenty of electrode gel and avoid drying
out by applying tape around all the edges
of the electrodes. Rinse the carbon rubber
electrodes and the skin with water after
use. Do not use detergent for the elec-
trodes.
• Self-adhesive multi-use electrodes are re-
moistened if necessary with a few drops
of water and kept air-tight (in a plastic
bag) on protective paper when they are
not in use.
• Never expose the stimulator to water.
Wipe it off with a damp cloth if necessary.
• Do not jerk cables or connections.
• The cables are best preserved if left at-
tached to the stimulator between sessions.
• No other maintenance of the device is re-
quired. Service life of the device can vary
depending on usage conditions. Typical
service life ifs 7 years.
• Never service the device while in use.
• The device should be operated in tempera-
tures between 10°C and 40°C, atmospher-
ic pressures between 50 and 106 kPa, and
relative humidity between 30% and 75%.
• The device should be transported and
stored in temperatures between -40 °C
and 70 °C, atmospheric pressures between
50 and 106 kPa and relative humidity be-
tween 10% and 90%.
• Contact manufacturer for assistance in
setting up, using or maintaining the equip-
ment or report events

• CEFAR EASY BELT
A lower-back belt is available as an accessory to the CEFAR EASY. The
CEFAR EASY belt makes it easier to relieve lower-back pain quickly.
The belt is designed to give you warming support and correct place-
ment – every time!
• CEFAR EASY SELF-ADHESIVE ELECTRODES
Electrodes get worn out and needs to be replaced. It is recommended
to replace the electrodes after approximately 20-40 times of usage.
• Y-CABLE
With the help of a so-called Y-cable, the number of electrodes
can be doubled.
9. TROUBLESHOOTING
THE STIMULATION DOES NOT FEEL THE SAME AS USUAL
• Check that all settings are correct and make sure that the electrodes are correctly placed.
· Slightly change the position of the electrodes.
THE STIMULATION CURRENT FEELS UNPLEASANT
· The skin is irritated.
· The electrodes begin to lose their stickiness and do not stick properly to the skin. Moisten
the adhesive surface with a few drops of water before placing on the skin.
· The electrodes are worn out and need to be replaced.
· Slightly change the position of the electrodes.

9
GB
THE STIMULATION FEELS WEAK OR NOT AT ALL
• Check if the batteries need to be replaced.
· Electrodes are too old and need replacement.
THE BROKEN CIRCUIT SYMBOL IS SHOWN ON THE DISPLAY SYMBOL
The broken circuit symbol indicates that the resistance is too high, or that a cable is broken.
· A too high resistance can be caused by a bad connection between the electrodes and your
skin, or that the electrodes need to be replaced.
· A cable breakage can be checked by pressing the cable´s pins against one another while in-
creasing the amplitude for the corresponding channel to 11 mA. If the amplitude now drops
to 0.0 mA and starts flashing, the cable needs to be replaced.
Note! Never increase the amplitude above 20 mA when you check for cable breaks, since this
can damage the stimulator.
THE STIMULATOR IS NOT WORKING
If the display to the left appears when you start the stimulator, it means that
the stimulator is broken and needs to be replaced. NOTE! Do not use the stim-
ulator - contact your Cefar dealer.

GB
• Across the head. Since the effects of stim-
ulation of the brain are unknown, stimula-
tion should not be applied across the head,
and electrodes should not be placed on
opposite sides of the head.
• Stimulation over compromised skin. Do not
apply stimulation over open wounds or
rashes, or over swollen, red, infected, or in-
flamed areas or skin eruptions (e.g., phlebi-
tis, thrombophlebitis, varicose veins).
• Stimulation near cancerous lesions. Do not
apply stimulation over, or in proximity to,
cancerous lesions.
• Stimulation over eyes. Do not apply stimu-
lation directly on the eyes.
• Environment. Electronic monitoring equip-
ment. Do not apply stimulation in the
presence of electronic monitoring equipment
(e.g., cardiac monitors, ECG alarms), which
may not operate properly when the elec-
trical stimulation device is in use.
• Bath or Shower. Do not apply stimulation
when the patient is in the bath or shower.
Do not apply stimulation in humid atmos-
phere exceeding 75% of relative humidity.
• Sleeping. Do not apply stimulation while
the patient is sleeping.
• Driving or operating machinery. Do not ap-
ply stimulation while the patient is driving,
operating machinery, or during any activity
in which electrical stimulation or involun-
tary muscle contraction can put the pa-
tient at risk of injury.
12.1. Contraindications
• Implanted electronic devices. Do not use
the device on patients who have a cardiac
pacemaker, implanted defibrillator, or other
implanted electronic device, because this
may cause electric shock, burns, electrical
interference, or death.
• TENS for Undiagnosed Pain. Do not use the
device as a TENS device on patients whose
pain syndromes are undiagnosed.
12.2. Warnings
• Consult with physician. Consult with the
patient’s physician before using the device,
because the device may cause lethal
rhythm disturbances to the heart in sus-
ceptible individuals.
• Skin condition. Apply stimulation only to
normal, intact, clean, healthy skin.
• Long term effects. The long-term effects of
chronic electrical stimulation are
unknown.
• Stimulation location. Stimulation over
Neck or Mouth. Do not apply stimulation
over the patient’s neck (especially the ca-
rotid sinus) or the patient’s mouth, because
this could cause severe muscle spasms re-
sulting in closure of the airway, difficulty in
breathing, or adverse effects on heart
rhythm or blood pressure.
• Stimulation across Chest. Do not apply
stimulation across the patient’s chest, be-
cause the introduction of electrical current
into the chest may cause rhythm disturbances
to the patient’s heart, which could be lethal.
12. PRECAUTIONARY MEASURES

13
GB
• Electrosurgical equipment or defibrillators.
Disconnect the stimulation electrodes be-
fore using electrosurgical equipment or
defibrillators. Otherwise skin burns may be
caused below the electrodes and the de-
vice might be destroyed.
• Magnetic Resonance Imaging. Do not
wear electrode or the device during
Magnetic Resonance Imaging (MRI) scans
as this may result in metal overheating
and causing skin burns in the area of the
electrode.
• Flammable or explosive environment. Do
not use the device in areas where there is
a risk of fire or explosion, such as oxygen-
rich environments, in the vicinity of flam-
mable anaesthetics, etc.
• Power supply. Never connect stimulation
cables to an external power supply as
there is a risk of electric shock.
• Near other equipment. Do not use the de-
vice beside or stacked on top of any other
equipment. If you must use it side by side
or on top of another system, you should
check that the device works properly in
the chosen configuration.
• Miscellaneous. Electrodes for Single
Patient. Do not share electrodes with oth-
er persons. All users should have individual
set of electrodes to prevent undesirable
skin reactions or disease transmission.
• Accessories. Use this device only with the
leads, electrodes, and accessories recom-
mended by the manufacturer. Use of other
accessories may adversely affect the
performance of the device or may result in
stronger electromagnetic emissions or reduce
the electromagnetic immunity of the device.
• No Modification. No modification of the
equipment is allowed.
12.3. Precautions
• Supervision. Use this device only under the
continued supervision of a licensed practi-
tioner. Electrode placement and stimula-
tion settings should be based on the guid-
ance of the prescribing practitioner.
• Manufacturer. The manufacturer does not
take any responsibility for any electrode
placements other than recommended.
• Pregnancy. The safety of electrical stimula-
tion during pregnancy has not been estab-
lished.
• Skin irritation. Some patients may experi-
ence skin irritation or hypersensitivity due
to the electrical stimulation or electrical
conductive medium (gel). The irritation
may be reduced by using an alternate con-
ductive medium or alternate electrode
placement. Some patients may experience
redness under the electrodes after a ses-
sion. This redness usually disappears with-
in a few hours. Advise the patient to con-
sult the clinician if the skin redness does
not disappear after a few hours. Do not
start another stimulation session in the
same area if the redness is still visible.
Don’t scratch the redness area.
• Heart Disease. Patients with suspected or
diagnosed heart disease should follow pre-
cautions recommended by their physicians.

14
GB • Epilepsy. Patients with suspected or diag-
nosed epilepsy should follow precautions
recommended by their physicians.
• Internal Bleeding. Use caution when the
patient has a tendency to bleed internally,
such as following an injury or fracture.
• After Surgery. Use caution following recent
surgical procedures when stimulation may
disrupt the patient’s healing process.
• Over uterus. Do not place electrodes di-
rectly over the uterus or connect pairs of
electrodes across the abdomen if you are
pregnant. The reason is that, theoretically,
the current could affect the foetus’s heart
(although there are no reports of it being
harmful).
• Lack of sensation. Use caution if stimula-
tion is applied over areas of skin that lack
normal sensation. Don’t apply stimulation
on patient unable to express themselves.
• Stimulation. The stimulator should only be
used with skin electrodes intended for
nerve and muscle stimulation. Muscle
soreness may occur after stimulation but
usually disappears within a week.
• Hot casing or batteries. Under extreme use
conditions, some parts of the casing might
reach up to 109 °F (43 °C). Use caution
when manipulating the batteries right af-
ter device use or when holding the device.
There is no particular health risk associat-
ed with this temperature besides your
comfort.
• Children. Keep this device out of the reach
of children.
• Electrode Size. Do not use electrodes with
an active area less than 16 cm2, as there
will be a risk of suffering a burn injury.
Caution should always be exercised with
current densities more than 2mA/ cm2.
• Strangulation. Do not wrap leadwires
around your neck, and keep them out of
the reach of children. Strangulation may
result from entanglement in the leadwires.
• Tripping. Care should be used to avoid trip-
ping on lead wires.
• Damaged Device or Accessories. Never use
the device or any of its accessories if it is
damaged (case, cables, etc.) or if the bat-
tery compartment is open as there is a risk
of electric shock. Carefully inspect the lead
wires and connectors prior to each use.
• Inspect Electrodes. Inspect electrodes be-
fore each use. Replace electrodes when
they begin to deteriorate or lose adhesion.
Poor contact between the electrodes and
the patient’s skin increases the risk of skin
irritation or burns. Electrodes will last
longer if used and stored according to in-
structions on electrode packaging. Attach
the electrodes in such a way that their en-
tire surface is in contact with the skin.
• Foreign bodies. Do not allow any foreign
bodies (soil, water, metal, etc.) to penetrate
the device and the battery compartment.
• Batteries. Do not carry batteries in a pock-
et, purse, or any other place where the ter-
minals could become short-circuited (e.g.
by way of paper clip). Intense heat could be
generated and injury may result. Never
open the battery cover during stimulation

15
GB
in order to avoid electrical shock. Remove
the batteries from the device if you do not
intend to use it for a prolonged period of
time (more than 3 months). Extended stor-
age of the batteries in the device might
lead to batteries and device damage.
• Cable. The cable is best preserved if left
attached to the stimulator between ses-
sions. Do not jerk the cable or connection.
• Heat and Cold products. The use of heat or
cold producing devices (e.g. electric heat-
ing blankets, heating pads or ice packs)
may impair performance of the electrode
or alter the patient’s circulation/sensitivity
and increase the risk of injury to the pa-
tient.
• Pulled muscles. Do not apply electrodes
over pulled muscles. Using the stimulator
on a previously extended muscle might
further pull such muscle. The higher the
stimulation intensity, the higher the risk to
further overextends such muscle.
• Additional Precautions for TENS
– TENS is not effective for pain of central
origin, including headache.
– TENS is not a substitute for pain medi-
cations and other pain management
therapies.
– TENS devices have no curative value.
– TENS is a symptomatic treatment and,
as such, suppresses the sensation of
pain that would otherwise serve as a
protective mechanism.
• Effectiveness of TENS is highly dependent
upon patient selection by a practitioner
qualified in the management of pain pa-
tients.
12.4. Dangers
• Electrodes. Any Electrode with a minimum
active area of 16 cm² may be used with this
device.Use of an electrode with an area
less than 16 cm² can cause burns when the
unit is used at higher intensities. Consult
your clinician prior to using any electrode
less than 16 cm².
12.5. Adverse reactions
• Patients may experience skin irritation and
burns beneath the stimulation electrodes
applied to the skin.
• Patients may experience headache and
other painful sensations during or follow-
ing the application of electrical stimulation
near the eyes and to the head and face.
• Patients should stop using the device and
should consult with their physicians if they
experience adverse reactions from the de-
vice.
• Precaution: Do not disconnect any stimu-
lation cables during a session while the
stimulator is switched on. Switch the stim-
ulator off first. Always turn off the stimula-
tor before moving or removing any elec-
trodes during a session.
• Precaution: Do not use electrodes with an
active area less than 16 cm2, as there will
be a risk of suffering a burn injury. Caution
should always be exercised with current
densities more than 2mA/cm2.

16
GB • Precaution: Do not apply stimulation in the
vicinity of metal. Remove jewelry, body
piercings, buckles or any other removable
metallic product or device in the area of
stimulation. Never use the electrodes con-
tra-laterally, i.e. do not use two pins con-
nected to the same channel on opposite
segments of the body.
• Precaution: Never carry out an initial stim-
ulation session on a person who is stand-
ing. The first five minutes of stimulation
must always be performed on a person
who is sitting or lying down. In rare in-
stances, people of a nervous disposition
may experience a vasovagal reaction. This
reaction is connected with fear of the
muscle stimulation as well as surprise at
seeing one of their muscles contract with-
out having intentionally contracted it
themselves. A vasovagal reaction causes
heart to slow down and blood pressure to
drop, which can make you feel weak and
faint. If this does occur, stop the stimula-
tion and lie down with the legs raised until
the feeling of weakness disappears (5 to 10
minutes).
• Precaution: Sudden temperature changes
can cause condensation to build up inside
the –stimulator. To prevent this, allow it to
reach room temperature before use.
