T.E.N.S. is simply a means of stimulating your body’s
own natural defences against pain. The unit produces
a gentle stimulus through pads normally placed over
the area of pain. This stimulus helps the body to
produce natural pain relievers called endorphins, and
to block the pain signal in its path to the brain.
The correct positioning of the pads is important, so
various body maps have been included to show pad
positioning in order to achieve maximum relief.
Many people feel immediate benefit from TENS.
However a minority may only achieve benefit after
repeated treatment sessions and over an extended
period of time.

BEFORE USE PLEASE READ THE FOLLOWING:
Statement: This unit is CE Marked, according to the

T.E.N.S. SHOULD NEVER BE USED TO MASK OR RELIEVE
UNDIAGNOSED PAIN. T.E.N.S. TREATS THE SYMPTOMS OF
PAIN, SO IT IS IMPORTANT THAT A DOCTOR MUST
DIAGNOSE THE CAUSE OF PAIN, BEFORE TREATMENT
BEGINS.
GENERAL PRECAUTIONS
1. Do not immerse TENS units in water
2. Do not place the TENS unit close to excessive heat
3. Use only the specified batteries: 2x 1.5volt AA Alkaline (LR6). Using of any
other battery could damage the unit.
4. Remove batteries if unit is not to be used for a long period of time.
5. Do not use the unit while asleep.
6. Keep the unit away from sources of high magnetic fields such as TV’S,
microwave ovens and hi-fi speakers, as these may affect the LCD screen.

The PADS
The pads that are supplied with your EasySTIM TENS Pain Relief unit are
self-adhesive and can be used several times. Skin must be allowed to breathe, so
the pads should be removed periodically. When not in use, the pads should be
placed onto the clear plastic shield.
The condition of the pads does affect the conductivity and, therefore, the
performance of the unit. When the pads initially lose their adhesive quality, it is
possible to reactivate their adhesiveness by applying a fine spray of water. Once
the pads have finally lost their adhesive quality. New Pads should be purchased
Allergic reactions to the self – adhesive pads can occur, even though they are
hypoallergenic.
· Do not apply to broken skin
· Do not apply a pad to skin that does not have normal sensation. If the
skin is numb, stimulation will not be felt and too great an intensity might
then be used accidentally.

Features:
1. When mode changes, the intensity will automatically go down to zero;
2. When the unit is turned on, it will automatically enter the mode that the
unit had worked in before the unit was turned off;
3.When the treatment timer is set, it will begin to count down one minute
by one minute; Once it count down to zero, the unit will automatically shut
off;
4. When the pulse rate, pulse width or intensity is being adjusted, the
auto-repeat function is available, when the key is held down over 1
second, it will automatically increased/decreased 1 step per 1/4 second.
5. By pressing” waveform key “and “Ch2 down” key simultaneously for 1

seconds the treatment time accumulated in minute can be displayed, or
return back to the previous normal display in toggle; by pressing “mode”
key & “timer” key for 2 seconds will clear the treatment time to zero.
7.When one or both of the electrodes does not touch the skin or it is

immediately down to zero (this feature is limited to the model TN-28 C).
8.When the batteries are low, the symbol of battery is flashing in 2 Hz
indicating that the batteries should be replaced;
9. When the unit intensity levels are 0 on both channels, and it has not
been in use for 5 minutes, the unit will be shut off automatically.
Please study the body maps in this guide, which show correct
positioning of the pads depending on your symptoms.
Red& Black fasteners on leads
At the end of the leads supplied with your unit, you will find Red
and black adapters. These are Cathode and Anode respectively.
The following general points are made for your information:
1. More sensation tends to come
from
the
black
adapter
(Cathode).
2. Where applicable place the
black adapter closer to the spinal
column; e. g. if the arm is to be
treated, place the black adaptor
higher up the arm than the red
adaptor.
