1. INTRODUCTION
The “itouch easy” as its name suggests is wonderfully easy to
use yet offers the very best in TENS pain relief. It is the result
of considerable research and represents a new generation of
TENS units.
2. SPECIAL FEATURES
• Pad Alarm
Perfect pad contact and condition is important to obtain maximum
benefit from any TENS unit. To ensure best performance the “itouch
easy” has been fitted with a “Pad Alarm” that shows you if the
contact of any of the four pads to your body is lost or below standard.
You might otherwise not be aware of the break in contact which
would interrupt the benefit being obtained from the unit.
• Comfort Strength Control (CSC)
Gives a gentle and reproducible stimulation. “CSC” monitors skin and
pad resistance and adjusts the output to maintain a constant feeling.
This gives you greater comfort and takes away the possibility of getting
an unpleasant spike in strength if a pad starts coming away from the
body. With “CSC” you can increase the strength on the “itouch easy”
in very small steps which is much more comfortable than conventional
TENS units.
• One Touch Memory Start
The “itouch easy” has a memory which allows it to remember the
last programme and intensity that was used. On start up, at the touch
of only ONE button, the “itouch easy” will automatically return to
the last programme used and to around 75% of the intensity. The
intensity gently “ramps” up to this level. The intensity can be stopped
at any time by pressing any button. The 75% level takes into account
accommodation that the body may have experienced.
• Mono Lead Wire
To ease set up and use, a new unique mono lead wire has been
developed. This lead wire has only one plug connector which goes into
the unit but at the other end it has four pin ends for connection
to pads.
OTHER FEATURES
• Medically proven programmes
The “itouch easy” is supplied with 8 preset programmes all of which
have been clinically proven to give high levels of pain relief.
• Backlit LCD screen for easy reading
Whenever a button is pressed the screen will light up from the back
making the screen easy to read and very clear.

3. HOW “TENS” WORKS
TENS stands for Transcutaneous Electrical Nerve Stimulation. TENS
stimulates your body’s own natural defences against pain, namely
the release of endorphins. TENS is totally safe, has been used
successfully by thousands of pain sufferers.
THE ADVANTAGES OF TENS
Totally Safe • Easy to Use • Drug Free
TENS sends a gentle stimulation through the skin which works
in TWO ways:-
• Pain Gate
Stimulating the sensory nerves, which carry touch and temperature
signals. These nerves go to the same connections in the spine as the
nerves carrying pain. A strong sensory signal will block the pain signal
travelling up the spine to the brain, this is known as closing the “Pain
Gate” and takes effect quite quickly after the unit is switched on.
You can use TENS several times a day, for as long as you like.
• Endorphin Release
At low frequency settings, and slightly stronger output, TENS drives the
motor nerves to produce a small repetitive muscle contraction. This is
seen by the brain as exercise, and this promotes release of Endorphins
- your body’s own natural pain killer. The relief builds up and normally
takes about 40 minutes to reach a maximum level which can last for
hours after the machine is switched off. By using TENS you can expect
to achieve a significant reduction in pain if not complete pain relief.
4. SIDE EFFECTS
There are no known side effects to TENS use and long-term TENS
use is not harmful.
5. THE PROGRAMMES
There is no one programme appropriate for a particular condition,
and the most appropriate varies from one person to another, even if
they have the same type of pain. Therefore, the selection of both the
programmes and the positioning of the pads should be performed on
an individual basis. You may need to try a few positions/programmes
before finding the one that suits you the best.
The following grid summarises the programmes available and how
they vary. All the programmes are effective for chronic pain, which
continues or recurs over a prolonged period and the programmes B,
C, D and H are effective for acute pain, such as pain caused by sports
injury or an accident. Some programmes are particularly effective for
certain pains. These have been indicated under the “Specific uses”
section. The “itouch easy” has 8 pre-set pain relief programmes.
If you are using TENS for the first time, it is recommended that
you start with programme A. TENS can be used for as long as is
necessary. Continuous treatment is fine, but electrode pads should be
repositioned regularly (at least every 12 hours) to allow the skin to be
exposed to the air. The Endorphin Release modes work better when the
strength is high enough to cause small muscle contractions.
Best results are achieved at between 20 and 40 minutes.

6. PROGRAMME INFORMATION
• Frequency (measured in Hz - pulses per second)
A frequency of 110 Hz is good at blocking pain signals.
A low frequency of 4 or 10 Hz allows for the release of endorphins,
the body’s natural morphine-like substances.
• Pulse Width (measured in µS - millionths of a second)
The “itouch easy” units offer a range of pulse widths from 50 to 250 µS.
The feeling through the pads will vary depending on the pulse width.
• Constant and Burst Modes
Constant mode is when the sensation is continuous as against Burst
mode when the sensation, is as its name implies, is one of on and off.
• Modulation Modes
Modulation is when either the frequency or pulse width sweep across
range of settings. This enables the body to receive many different signals
and can be very beneficial and lessen any effect of accommodation.
See programmes F and G.
• Han Stimulation
Professor Han in China found that alternating very low (2Hz) and
medium (110Hz) frequency gave best pain relief in his research studies.
See programme H.
Programme Output Frequency Hz Pulse Width µS
A Constant 110 50
B Constant 4 200
C Burst 2 bursts of 100Hz per sec.
D Constant 10 200

*F Modulated Strength/
Duration 110 50-250
**G Modulated 20-110 200
***H Han Stimulation 2Hz/110Hz 200/100
*F - The pulse width modulates from 50 up to 250 and back in 12 seconds,
whilst intensity is modulating from chosen level down 70% and back.
**G - The frequency modulates from 20 -100 and back in 12 seconds.
***H - The frequency is set at 2 Hz for 3 seconds and then changes to
110Hz for 3 seconds. This is repeated continuously.

10. CONNECTING MONO LEADWIRE
11. POSITIONING OF ELECTRODE PADS
The following body maps in this instruction
booklet will show you where to place the
electrode pads for a range of common
complaints, dependent on your symptoms.
For symptoms not illustrated, apply the
pads around/near to the source of the
pain or seek advice from your doctor
or physiotherapist.
The electrode pads must always be used in
pairs, so that the signal can flow in a circuit.
NOTE: Always check unit is OFF before
attaching or removing pads.
Insert the Mono leadwire plug into the base
of the unit. Please note that it has been
designed to only insert one way.
Attaching the electrode pads to
Mono Lead wire
At the other end of the Mono Lead wire,
the lead wire splits into four pin ends,
2 white and 2 black. Push the pin ends into
the pigtail ends of the electrode pads.
The mono lead wire can be split as required
and adjust the toggle as necessary.
Mono Lead wire colour coding
L-IT … Mono Lead wire (dual channel), as
supplied with the unit, has FOUR wires for
use with four pads. Two of the wires are
white and the other two are black. Channel
1controls the output to the white wires and
Channel 2 to the black wires.
It is also possible to use L-IT Mono Lead wire (dual channel) with
only two pads using only the white lead wires. In which case the
black lead wires, as they are not in use, can safely be put to the
side - There is no risk from the exposed pins.
L-IT-1 Mono Lead wire (single channel) can be purchased as an
accessory. This lead is for those who only wish to use two pads
through Channel 1.

11. POSITIONING OF ELECTRODE PADS (cont)
Where only two pads are shown on the arm, shoulder, and leg, use
the other two pads either on the opposite limb or place all four pads
on the same limb in a square pattern with each pad being about 4
inches apart.
12. GENERAL PAD ADVICE
• The electrode pads supplied are reusable but are for single
patient use.
• In order to obtain the best conductivity through the pads
always ensure that they are in good condition and tacky.
• Before use make sure your skin is clean and dry.
• Peel the electrode pads from their protective plastic shield by
holding and lifting one corner of the pad and pulling. Do not
pull on the pigtail wire of the pad.
• After use always replace the pads on the plastic liner and
replace in the re-sealable plastic bag.
• If the pads dry out then it is best to buy a replacement pack
of electrodes. In an emergency it may be possible to restore
some of the tackiness of the pad by adding a tiny drop of water
on each pad and spreading around. If too much water is added
the pads will become too soft then it is suggested in order to try
re-establish some adhesiveness to place them sticky side up in a
refrigerator for a few hours.
• In very hot weather the gel on the pads may become soft. In
such cases place the pads, still on their plastic liners and in
their bag into a fridge until they return to their normal condition.

22
21
12. GENERAL PAD ADVICE (cont)
• The pads provided are latex –free.
• Replace pads when they lose their stickiness.
Poor connection may cause discomfort and skin irritation
• Storage life of an unopened pack of electrodes is 2 years.
This may be affected by very high temperatures or very
low humidity.
13. PAD ALARM
Perfect pad contact and condition is important to obtain maximum
benefit from any TENS unit. To ensure best performance the
“itouch easy” has been fitted with a “Pad Alarm”.
If the contact between any of the pads and the skin or the quality
of the pads is below the required standard the pad alarm will be
triggered. An audible bleep will be heard and at the top of the
screen the word “PADS” will flash.
When the pad alarm is triggered, the Comfort Strength Control
facility will automatically lower the intensity to a comfortable level
thereby avoiding the possibility of any electrical shock, however
small. If the alarm is triggered due to the pads coming partly away
from the body, then when they are put back the intensity will
automatically return to the original level.
The “PADS” alarm does not function on either channel when the
intensity levels are below 5.0mA.

24
23
14. THE BELT CRADLE
In order to be able to wear the “itouch easy” around the waist a
belt cradle is supplied.
Attaching the belt cradle: To attach the belt cradle push the
“itouch easy” upwards into the cradle so that it slides between
the two sides of the cradle and slots into it with the two notches
on the inside of the cradle going into the two holes in the top of
the unit.
Removing the belt cradle: To remove the cradle push a finger
through the hole at the back of the cradle while holding onto it.
NB: Do not attach the mono leadwire before attaching the belt
craddle to the unit and it is necessary to detach the mono leadwire
before removing the craddle
15. CLEANING
The case and lead wires can be cleaned by wiping with a damp
cloth and a solution of mild soap and water. Wipe dry.
Do not immerse your TENS machine in water.

17. CAUTIONS & WARNINGS
Do not use TENS :
• If you have a heart pacemaker or have a heart rhythm problem.
TENS in the direct vicinity of a pacemaker may affect some
models. If TENS is applied on the front of the neck this can
affect your heart rate. Very strong TENS across the chest may
cause an extra heartbeat.
• If you have epilepsy. TENS may affect seizure threshold.
• During the first three months of pregnancy. It is not known
whether TENS may affect foetal development.
• On the abdomen in the later stages of pregnancy.
Stop use immediately if you experience unexpected contractions.
• When driving, operating machinery, or similar actions
needing fine control. Loose pads, damaged leads, or
sudden changes in contact may cause brief involuntary
muscle movements.
• To mask or relieve undiagnosed pain.
May delay diagnosis of progressive condition.
Caution :
• Observe caution when using the Itouch Plus at the same
time as being connected to monitoring equipment with
body worn electrode pads. It may interfere with the signals
being monitored.
