2. HOW “TENS” WORKS
T.E.N.S. stands for Transcutaneous Electrical Nerve Stimulation.
T.E.N.S. stimulates your body’s own natural defences against pain, namely the release of endorphins.
T.E.N.S. is totally safe and has been used successfully by thousands of pain sufferers.
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.
3.
SIDE EFFECTS
There are no known side effects to TENS use and long-term TENS use is not harmful.

6. BELT CLIP
A belt clip is provided to allow you to attach the touch TENS to your clothing. It
can be inserted either way up. Slide along the base of the unit until
it locks in position.
You can also hang the unit from your neck using the hook provided. Use thread or wool that will snap
easily if the unit snags on something.
7. THE PROGRAMMES
There is no one programme for a particular condition, and the best choice varies from one person to another,
even if they have the same type of pain.
Each user needs to select both the programme and the positioning of the pads that is best for them.
You may need to try a few positions/programmes before finding the one that suits you.
If you are using TENS for the first time, it is recommended that you start with Programme A, which
gives the gentlest stimulation.
The Touch TENS has 8 pre-set pain relief programmes.
Research has shown that some programmes are particularly effective for certain pains. These have been
indicated under the “Specific uses” section.
The following grid summarises the programmes available and
how they vary.

USAGE
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. Longer use may cause muscle
ache.
8. INFORMATION ABOUT THE PROGRAMME SETTINGS
• Frequency (measured in Hz - pulses per second)
PAIN GATE: A high frequency of 110Hz is good at blocking pain signals.
ENDORPHINE RELEASE: A low frequency of 4 or 10Hz allows for the release of endorphins, the body’s
natural morphine-like substances.
• Pulse Width (measure in μS - millionths of a second)
The Touch TENS unit has pulse widths of 50 and 200 μS. Higher Pulse Widths are more likely to cause
muscle contractions.
• 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
Invented by a Professor Han, this alternates between high and low frequencies to give - in theory - the best
pain relief.

ON/OFF
To turn the unit ON, press the ON/OFF button on the side of the unit and hold for 2
secs until the display shows.
To turn the unit OFF, press the ON/OFF button on the side of the unit and hold for 2 seconds
until the display stops.
The unit will turn OFF automatically :
When the Timer reaches zero,
If it is left at zero strength for more than 5 minutes.
At first use, or after changing batteries, the display shows that the unit is automatically set in Programme A
at zero strength.
On the top of the XL-Y1 unit there are four coloured buttons:
STRENGTH CONTROLS
The BLUE BUTTONS, marked ,  are strength controls.
The left hand buttons change strength in the left hand lead, Ch1, and the right hand
buttons change the right hand lead, Ch2.
To increase strength in steps of 1, press and release the top part of the two blue buttons marked .
The strength levels are shown on the LCD.
The strength control buttons will not operate until the unit is properly connected to you. Touch
TENS detects a disconnection and automatically returns the strength to zero.
The unit has 60 levels of strength.
If you hold down the button for 2 seconds, the strength will start scrolling.
You may feel nothing over the first few presses. Continue pressing until the sensation is strong but
comfortable. Further increases during use may be necessary if your body becomes used to the sensation.
To lower the strength, press and release the lower part of the blue buttons marked .
PROGRAMME CONTROL
The YELLOW BUTTON, marked #, is the Programme control.
The Touch TENS has eight different, specially developed programmes lettered A-H.
When the unit is first switched on it automatically enters
PROGRAMME A.
Each time you press and release the YELLOW BUTTON, the programme changes and the letter is shown
on the LCD.
Each time you change the programme, the strength level reverts back to zero.
This is a
safety feature to alleviate any sudden feeling of a surge, as each Programme gives a different sensation.
TIMER
The GREEN BUTTON, marked with a clock symbol, can be used to set the session
duration.
When you switch the unit on, it is automatically set at continuous, (displayed as CO) which
means that the unit will continue functioning until you switch it off.
You can set session times of 20,40, or 60 minutes by pressing the green button repeatedly.
The LCD shows the session duration next to the clock symbol. The unit
automatically counts down the minutes set and switches off when this reaches zero.
A LOW BATTERY display, with a symbol of empty batteries, will show when
you need to change the batteries. The unit will shut down about 2 minutes after this.
KEYPAD LOCK
If you do not press any keys for 30 seconds, the keypad will lock so that only the keys marked ▼
will work. This is to avoid accidental changes in setting.
To unlock, press either ▼ key.
OPEN CIRCUIT CUTOUT
If the Touch TENS is not correctly connected to your body, the strength will
automatically reset to zero. This is to prevent sudden changes if a broken connection is re-made.
MEMORY
The XL-Y1 has a Memory with three functions:
1) Programme Retention. When you switch the unit On, it will automatically start in the Programme which
was being used when it was switched Off.
2) Frequency of Use. Press Programme and Left blue ▲ together and hold down for 3
seconds. The display will show T (for no. of Times) and a number from 1 to 999, indicating the number
of times the unit has been used.
Press the same buttons again to return to normal controls.
3) Elapsed Time. Press Programme and Right blue ▲ together and hold down for 3
seconds. The display will show U (for Usage) and a number from 1 to 999 hours,
indicating the total number of hours the unit has been above zero strength.
Press the Programme button again to return to normal controls.
Memory Reset.
To reset Memory to zero, hold down the Programme and Timer buttons together for 3 seconds.
11. CONNECTING LEAD WIRES
Insert the leadwire plug into the base of the unit.
Attaching the electrode pads to Lead wire
Push the pin ends firmly into the pigtail ends of the electrode pads.
The leadwires may be damaged by rough handling, and should be treated with care.
Lead wire colour coding
The ends of the lead wire are coloured white or red. This coding is provided for some professional
uses, For most purposes, the orientation makes no difference, and you can ignore this colour coding.
12.
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.
NOTE: Touch TENS resets strength to zero if the pad or lead is disconnected from your body.
This is to prevent sudden changes in sensation when the pad is re-connected.
For areas that are difficult to reach, why not ask a friend to help you attach the pads?
See Section 16 for information on where you should not place pads.

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.
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.
14. CLEANING
Clean the case and lead wires at least once a week by wiping with a damp cloth and a solution of mild soap
and water. Wipe dry.
Do not immerse your TENS machine in water.
Do not use any other cleaning solution than soap and water.
