Getting to Know Your TENS Unit
Transcutaneous Electrical Nerve Stimulation
(TENS) units are used for temporary relief of sore
and aching muscles in the body due to exercise or
strenuous activities such as normal household work
activities. The 4 channels deliver tiny electrical
impulses sent through the skin to the nerves to
help manage pain by signaling the body to produce
endorphins, the body’s natural pain killer.
The TENS Unit is designed to be used for temporary
relief of pain associated with sore and aching
muscles in the shoulder, waist, back, neck, upper
extremities (arm) and lower extremities (leg) due
to strain from exercise or normal household work
activities. It should be applied to normal, healthy, and
dry skin of adult patients.
The TENS unit works best on acute pain because it
is localized. Acute pain occurs in 1 area for less than
3 months. If you have chronic pain (often including
experiencing pain in more than 1 area and for
longer than 6 months), then the chronic pain may
be compounded by other issues that the TENS unit
cannot address.
The TENS unit cannot cure pain or the original cause
of the pain. It can only provide temporary relief or
reduction of pain.
Use the TENS unit as soon as your pain begins. Start
with 1 session. If you address your pain early, it may
prevent the pain from becoming worse.
Controlling Pain
15
The TENS unit should be used once a day, for up to
30 minutes for each treatment area. Depending on
the level of pain, you may use the TENS unit up to 3
times a day for a maximum of 90 minutes total. Do
not use more than 3 times a day or 90 minutes total
per treatment area.
When turning off the TENS unit, always turn
it off with pads still adhered to skin. Rate your
pain between 1 (low) and 20 (high) to check your
progress.
Intensity is based upon your level of comfort. When
learning how to use the TENS unit, begin with a low
intensity and use the TENS unit for a short period
of time. Use caution when working with higher
intensities at the limit of what you can tolerate. Do
not exceed your comfort level.
Length and Intensity
Stop using the TENS unit if:
• Pain has reduced or stopped.
• You experience an adverse reaction such as
skin irritation, redness, burns, headaches, other
painful sensations, or any increased discomfort.
• Your pain becomes chronic and severe, or
continues for more than 5 days.
Note:
• If pain does not improve and you become
sore from overuse, stop using and do not
treat those areas for 2 days. If this happens
again, reduce the treatment time and
intensity settings for future treatments.
• If you feel pain, dizziness, discomfort, or
nausea while using the TENS unit, call your
physician or medical practitioner.
16
1. Prep the area by cleaning your skin. Wash and
pat dry.
2. Gently peel the pads from the plastic and place at
least 2 in / 5 cm apart on clean, dry, and healthy
skin near or surrounding the area of pain.
Using the TENS Unit
Note:
• Before placing electrodes on skin, make
sure the TENS unit is completely turned
OFF or the intensities are set to 0.
• Do not allow the pads to touch each other.
• Never remove the self-adhesive pads from
the skin while the TENS unit is turned on.

(see Charging the Battery, page 21).
Electrode Placement Guide
Hip: Pain in the hip area is often
the result of wearing of the
joints (arthrosis). Pain in the hip
region may be treated with the
application of electrodes above
and below the joint. In addition,
pain may also radiate outwards,
e.g. towards the groin. In this
case, an electrode is applied
to the main pain point on the
hip while a second electrode is
applied in the direction that the
pain is radiating.
17
Shoulder: Attach 1 set of
electrodes in front and 1 set on
the back of the muscle where you
feel pain. Also attach both pads
on the shoulder according to your
pain.
Upper Arm: Attach both
electrodes on either side where
you feel pain.
Elbow: Attach both sets of
electrodes on either side of the
joint where you feel pain.
Neck: Attach both sets of pads to
the back of the neck. Do not place
on carotid artery or throat.
Lower Back/Lumbar: Attach
both sets of electrodes to the
lower back with the backbone in
the center. Do not place on the
backbone or spine.
Upper Back: Attach both sets
of electrodes to the upper back
with the backbone in the center.
Do not place on the backbone or
spine.
18
Wrist/Hand: Attach both sets of
electrodes to the hand where you
feel pain.
Knee/Joint: Attach both sets of
electrodes above or above and
below the joint with pain.
Calf: Attach both electrodes on
the calf or leg where you feel
pain.

Interference may occur in the vicinity of
equipment marked with the following symbol:
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reection from structures, objects and people.
A. Field strengths from xed RF transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment due to xed RF transmitters, an electromagnetic site survey
should be considered. If the measured eld strength in the location in which device is used exceeds the applicable RF
compliance level above, device should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating device.
B. Over the frequency range 0.15 MHz to 80 MHz, eld strengths should be less than 3 V/m.
