1. INTRODUCTION
Device Description & Principles of
Design
The TENS One is an accurate and
versatile, digital TENS unit that is easy
to use, with simple settings and rotating
strength control knobs. It can help
manage the pain from a wide range of
conditions.
Chronic pain: Back pain. Lumbago,
sciatica pain and arthritic pain.
Musculoskeletal pain: fibromyalgia and
injuries (sprains, tears, fractures,
muscle strain).
Acute pain: Dental and facial pain,
postoperative pain and neuropathic
pain (and neuralgias).
TENS machines can be used alone for
pain relief or be combined with other
treatments.
2. INTENDED USE
TENS One is intended for the
relief of pain associated with
sore or aching muscles of the lower
back, arms, or legs due to strain from
exercise or normal household and work
activities.

4. 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. TENS is totally
6
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
It stimulates 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.
When the gate is open, pain messages
get through to the brain and we feel
pain. When the gate is closed, these
pain messages are blocked and we do
not feel pain.
Evidence suggests that TENS produce
pain relief in a similar way to ‘rubbing
the pain better’. The pain gate can be
closed by activation of
mechanoreceptors through ‘rubbing the
skin’.
Scientifically, the pain gate works by
release of chemical in the synapse at
spinal level that inhibits transmission of
pain signal.
Endorphin Release
At low frequency
settings, and
slightly stronger
outputs, TENS
drives the motor
nerves to produce
a small repetitive
muscle
contraction. This is seen by the brain as
exercise, and this promotes the 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 relief from pain.
TENS is effective for pain from a very
wide range of causes.
TENS machines can be used to help
reduce pain from problems in
muscles, joints and nerves.
It can be also used for people with
musculoskeletal pain such as long-
term (chronic) back pain or knee joint
arthritis. They are also often used for
pain relief in the early stages of
labour (see perfect mamaTENS),
particularly whilst a pregnant woman
remains at home.
TENS may also be used to treat
many types of pain, such as period
pain and endometriosis (see Ova+),
cystitis, sports injuries, fibromyalgia
and neuralgia, plantar fasciitis, post-
operative pain, TMJ disorder,
diabetic neuropathy, osteo-arthritis
and sometimes non-painful
conditions such as travel sickness.
7
You can use low frequency (<10 Hz)
programmes on acupuncture points,
to achieve similar effects to
acupuncture.
With neurogenic pain (caused by
inflamed nerves) such as neuralgia,
TENS may start by increasing the
pain. We recommend that you only
use TENS for these conditions under
medical supervision.
You can safely use TENS as long as
it gives you pain relief. The effect
may wear off after a few hours (this
is called “accommodation”). If this
happens, take a break of an hour or
so before trying again. If you use
settings that cause muscle
movement for more than 40 minutes,
you may experience aching muscles
a few hours later.
5. CONTRAINDICATIONS,
WARNINGS &
CAUTIONS
In this manual:
A Contraindication is used
when a device should not be
used because the risk of use
clearly outweighs any foreseeable
benefits and may result in serious injury
or death.
A Warning is used when
failure to follow the instructions
may result in serious injury or
death.
A Caution is used when failure
to follow the instructions may
result in a minor or moderate
injury, or damage to the device or other
property.
Notes are used to provide
clarification or
recommendation.
CONTRAINDICATIONS:
Do NOT use if you have a pacemaker
(or if you have a heart rhythm problem)
or with any electronic medical devices.
Using this unit with electronic medical
devices may cause erroneous
operation of the device. Stimulation in
the direct vicinity of an implanted device
may affect some models.
Do NOT use during the first three
months of pregnancy. It is not known
whether TENS may affect foetal
development.
Do NOT use on the abdomen in the
later stages of pregnancy. Stop using
immediately if you experience
unexpected contractions.
WARNINGS:
Do NOT use to mask or relieve
undiagnosed pain. This may delay
diagnosis of a progressive condition.
Do NOT use if you have, in the area
being treated: active or suspected
cancer or undiagnosed pain with a
history of cancer. Stimulation directly
through a confirmed or suspected
malignancy should be avoided as it may
stimulate growth and promote spread of
cancer cells.
If you are in the care of a physician,
consult with your physician before using
this device.
8
If you have had medical or physical
treatment for your pain, consult with
your physician before using this device.
If your pain does not improve, becomes
more than mild, or continues for more
than five days, stop using the device
and consult with your physician.
Do NOT use electrodes on the front of
the neck. Stimulation on the front of the
neck can affect your heart rate or cause
contraction of the throat.
Do NOT use electrodes across the
chest. Very strong stimulation across
the chest may cause an extra heartbeat
and/or rhythm disturbances to your
heart, which could be lethal.
Do NOT use Tens One while
simultaneously connected to high
frequency surgical equipment as it may
result in burns at the site of stimulator
electrodes and possible damage to the
stimulator.
Do NOT use Tens One in close
proximity (e.g. 1 m) to a shortwave or
microwave as this may produce
instability in the stimulator output.
Do NOT use electrodes near the thorax
as this may increase the risk of cardiac
fibrillation.
Do not apply stimulation when in the
bath or shower.
Do not apply stimulation while sleeping.
Do NOT use when driving, operating
machinery, or similar actions needing
muscular control. Loose electrode
pads, damaged leads, or sudden
changes in contact may cause brief
involuntary muscle movements.
Consult with your physician before
using this device because the device
may cause lethal rhythm disturbances
to the heart in susceptible individuals.
CAUTIONS:
TENS is not a substitute for pain
medications 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 is highly dependent upon
patient selection by a practitioner
qualified in the management of pain
patients.
The long-term effects of electrical
stimulation are unknown.
The safety of electrical stimulation
during pregnancy has not been
established.
If you have suspected or diagnosed
heart disease, you should follow
precautions recommended by your
physician.
Use caution if stimulation is applied
over the menstruating or pregnant
uterus.
Caution should be used if you have a
bleeding disorder as stimulation may
increase blood flow to the stimulated
region.
Caution should be used if you have
suspected or diagnosed epilepsy as
electrical stimulation may affect seizure
threshold.
Caution should be observed when
using the device at the same time as
being connected to monitoring
equipment with body worn electrode
pads. It may interfere with the signals
being monitored.
9
Caution should be used following
recent surgical procedures. Stimulation
may disrupt the healing process.
Caution Simultaneous connection to
high frequency surgical equipment may
result in burns and damage to the
stimulator.
Caution Not intended for use in an
oxygen rich environment.
Caution Not intended for use in
conjunction with flammable
anaesthetics or flammable agents.
Caution The patient is an intended
operator.
Caution Do not service and maintain
the device while in use.
Caution Maintenance and all repairs
should only be carried out by an
authorized agency. The manufacturer
will not be held responsible for the
results of maintenance or repairs by
unauthorized persons.
If necessary, we will provide circuit
diagrams, component part lists or other
information that will assist authorized
service personnel to repair the device.
Caution The operator should not touch
the patient at the same time when
touching the battery output.
Caution Keep away from pets and
pests
Caution Do not permit use by children
unable to understand the instructions or
persons with cognitive disabilities, i.e.;
Alzheimer’s disease or dementia.
Caution Keep away from children
under 5 years of age. Long cord - risk
of strangulation in infants.
DO NOT PLACE ELECTRODE PADS:
On skin, which does not have normal
sensation. If the skin is numb too
great a strength may be used, which
could result in skin inflammation.
On broken skin. The electrode pads
could encourage infection.
On the front of the neck. This could
cause the airway to close, giving
breathing problems. May cause
sudden drop in blood pressure
(vasovagal response).
Over the eyes. May affect eyesight
or cause headaches.
Across the front of the head. Effect
on patients who have had strokes or
seizures is not known. May affect
your sense of balance. The effects of
stimulation on the brain are
unknown.
ELECTRODE PADS CAUTION:
Caution: Do not ignore any allergic
reaction to the electrode pads: If a skin
irritation develops, stop using TENS, as
this type of electrodes may not
be suitable for you. Alternative
electrode pads specially made for
sensitive skin are available.
Caution: Do not use this device with
leads or electrode pads other than
those recommended by the
manufacturer. Performance may vary
from specification. Electrodes with
smaller surface area may cause tissue
irritation.
Caution: Do not use high intensity
settings if electrodes are smaller than
50x50mm.
TO KEEP YOUR DEVICE IN GOOD
WORKING ORDER, OBSERVE THE
FOLLOWING ADDITIONAL
CAUTIONS:
Caution: Do not immerse your device
in water or place it close to excessive
heat such as a fireplace or radiant
10
heater or sources of high humidity such
as a nebulizer or kettle as this may
cause it to cease to operate correctly.
Caution: Keep the device away from
sunlight, as long-term exposure to
sunlight may affect the rubber causing
it to become less elastic and crack.
Caution: Keep the device away from
lint and dust, as long-term exposure to

Caution: There are no serviceable user
parts. Do not attempt to open or modify
the TENS unit. This may affect the safe
operation of the unit and will invalidate
the warranty.
6. INFORMATION ABOUT
THE PROGRAMME
SETTINGS
The Frequency and Pulse Width
settings can be adjusted which allow for
different sensations through the
electrode pads and suppress pain in
different ways.
Frequency (measured in Hz -
pulses per second)
PAIN GATE: A high frequency of 110
Hz is good at blocking pain signals.
ENDORPHINE RELEASE: 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 TENS One unit has pulse widths of
50 to 250 μs. Generally speaking, the
higher the pulse width, the more
"aggressive" the stimulation feels, and
eventually, if the pulse width is set high
enough, it will usually elicit a muscle
contraction, which is typically not the
desired result with a TENS unit.
However, if the pulse width is too low,
the patient may not perceive the
stimulation. Pulse Rate is important
because different frequency settings
target different nerve groups and the
setting will determine if the "Gate
Theory" or "Endorphin Theory" of TENS
will be used.
Constant and Burst Modes
Constant mode is when the sensation is
continuous versus Burst mode when
the sensation, as its name implies, is
one of on and off. Constant mode is
often used for acute pain via Pain Gate
Effect whereas Burst mode is useful in
chronic pain relief. Burst gives a
combination of Pain Gate and
Endorphin Release, but the squeezing
feeling may not be as comfortable. The
sensation in Burst is more of a
‘grabbing’, ‘clawing’ type and usually
more by way of muscle twitching than
with the high or low frequency modes.
The stimulation intensity will need to be
relatively high. In Constant mode, the
sensation is continuous and is more of
a tingling pins and needles type.
Modulation Mode
Modulation is when either the
frequency or pulse width sweep across
range of settings. In modulation mode,
the machine delivers a less regular
pattern of TENS stimulation in an
attempt to reduce or minimise the
11
accommodation effects of regular,
patterned stimulation. This is potentially
most useful for patients who use TENS
for several hours a day, if for no other
reason than accommodation occurs at
a slower rate and therefore less
intensity adjustment may be required.
Note: If you are using TENS for
the first time, it is
recommended that you start
with a setting of 110 Hz and 50 μs.
For more information about which
settings to choose for the different type
of pain, refer to section 7.3.
7. MODES
TENS One has three different modes:
N: Constant/Normal stimulation with
adjustable parameters
B: Burst stimulation with adjustable
settings.
Two stimulations per second, 250 ms
on, 250 ms off; pulse width and pulse
rate are selectable.
M: Stimulation with modulated pulse
width and modulated frequency.
Pulse rate modulates from PR1
to PR2 or PR2 to PR1 while pulse
width modulates from PW1 to PW2 or
PW2 to PW1 within 6 seconds. PR1
and PW1 are adjustable. PR2 is 50
Hz fixed, PW2 is 200 μs fixed.
To choose a mode, press the button
MODE, until you reach the desired
mode.
7.1. PARAMETERS
Professor Han did research that
showed that P increased as the
frequency increased but only tested
up to 100 Hz.
And that E decreases as the frequency
increases.
So, E is less effective when the
frequency is >10 Hz and P is less
effective when the frequency is <80 Hz.
Most clinical research on P has been
done at 80 Hz or 100 Hz.
Many professional users believe that
the response to TENS varies between
individuals, and that you can get the
best response by choosing the
frequency that suits your nervous
system the best. They suggest that you
start at 80 Hz or 110 Hz, then try
different the frequency until you find
one that gives you better pain relief.
7.2. SELECTING THE
PARAMETERS
Before adjusting the parameters, select
the mode of your choice.
Frequency: To increase the
frequency (or pulse rate), rotate the
pulse rate knob clockwise. To
decrease, rotate the knob anti-
clockwise. You can select a frequency
from 1 to 150 Hz.
Pulse Width: To increase the pulse
width, rotate the pulse width knob
clockwise. To decrease, rotate the
knob anti-clockwise. You can select a
pulse width from 50 to 250 µs in steps
of 10 µs.
Timer: For each mode, you can select
a treatment duration with the timer
button. You can select a duration of C
(Continuous), 15, 30, 45, 60 and 90
minutes.
See section 6 for more information on
the choice of settings.
12
7.3. RECOMMENDED
SETTINGS
The tables oppposite are only
recommendations.
There is not 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.
Therefore, the selection of both the
settings and the positioning of the
electrode pads should be performed on
an individual basis. You may need to try
a few positions/programmes before
finding the one that suits you.
7.4. MODE USAGE
TENS can be used for as long as it is
necessary. Continuous treatment is
fine, but the electrode pads should be
repositioned regularly (at least every 12
hours) to allow the skin to be exposed
to the air.
The Endorphin Release programmes
work better when the strength is high
enough to cause small muscle
contractions. Best results are achieved
with a session duration between 15 and
45 minutes. Longer use may cause
muscle ache.
8. ELECTRODE PADS
8.1. PAD POSITIONING
The electrode pads must always be
used in pairs (two electrode pads on
each channel), so that the signal can
flow in a circuit.
TENS works one vertebra at a time.

nerves that enter the spine at the
same level as the nerve carrying
your pain. Since you don’t know
exactly where your nerves are, the
easiest way is to apply the electrode
pads around/near the source of the
pain.
TENS activates the nerves best if it
travels along the nerve rather than
across it. So place one pad further
from the spine than the source of the
pain, and one closer.
The nerves wrap around the limbs
and torso, so you may have to try a
few positions before you get the best
effect.
If the pain is in, or close to, your
spine you can place one pad either
side of the spine.
You may feel more sensation in one
pad than the other. This is normal
it depends on where the electrode
pads are in relation to your nerves.
For areas that are difficult to reach, why
not ask a friend to help you attach the
electrode pads?
Always check that the unit is OFF
before attaching or removing
electrode pads.
Note: See examples of
positioning in the instructions
enclosed with your electrode
pads.
8.2. PAD ADVICE
The electrode pads supplied are
reusable but for single patient use.
The adhesive is a peelable hydrogel
(water based).
In order to obtain the best
conductivity through the electrode
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
electrode pads on the plastic liner
and replace them in the re-sealable
plastic bag.
If the electrode pads dry out, then it
is best to buy a replacement pack. 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
electrode pad will become too soft. If
that happens then it is suggested in
order to try and 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
electrode pads may become soft. In
such cases place them, still on their
plastic liners and in their pouch into
a fridge until they return to their
normal condition.
The electrode pads provided are
latex-free.
Replace the electrode pads when
they lose their stickiness.
Poor connection may cause
discomfort and skin irritation.
Storage life of an unopened pack of
electrode pads is 2 years. This may
be affected by very high
temperatures or very low humidity.

MODE button, the mode changes and
the letter is shown on the LCD.
Before changing the mode, it is strongly
recommended to bring the intensity
back to zero.
Each time you change the mode, the
strength level reverts back to zero for
three second before ramping back up to
the previous level of intensity.
TREATMENT TIMER
The TIMER button can be
used to set the session
duration. Press and release to change
the session time. You can set session
times of C (Continuous) or 15, 30, 45,
60 or 90 minutes.
The LCD shows the session duration
next to the min symbol. The unit
automatically counts down the minutes
set, once it reaches 0 the display will
flash until the device is manually
switched off.
PULSE RATE CONTROLS
To increase the frequency (or
pulse rate), rotate the pulse rate
knob clockwise. To decrease, rotate the
knob anti-clockwise.
PULSE WIDTH CONTROLS
To increase the pulse width,
rotate the pulse width knob
clockwise. To decrease, rotate the knob
anti-clockwise.
STRENGTH CONTROLS
On the top of the unit, there
are two rotating control knobs.

strength in the left-hand lead and the
right-hand knob change the right-hand
lead.
To increase the strength, turn the knobs
clockwise.
To decrease the strength, turn the
knobs counter-clockwise.
The strength levels are shown on the
LCD.
The unit has 20 levels of strength, each
step is 4mA. You may feel nothing over
the first few levels. Continue turning the
knobs carefully until the sensation is
strong but comfortable. Further
increases during use may be necessary

if your body becomes used to the
sensation.
The orange LED on the output socket
indicates that there is an active output.
The LED will remain on as long as the
intensity is above 0.
LOW BATTERY
The LED indicator will flash
when you need to change
the batteries. The unit will
shut down about 2 minutes after this.
OPEN CIRCUIT CUTOUT
If the TENS One is not correctly
connected to your body, the strength in
the channel which is not properly
connected will automatically reset to
zero for 3 seconds and the display will
flash. After 3 seconds, the intensity will
start ramping back up to the intensity
selected. This also happens when
changing the mode. This is to prevent
sudden changes in sensations.
11. SETTING UP AND
USING THE TENS ONE
11.1. INSTALLATION OF
BATTERIES
1) Remove the battery cover.
2) Insert batteries.
Ensure that the batteries are inserted
the right way as shown in battery
compartment and that the ribbon is
behind them.
4) Replace the battery cover.
Caution: Remove batteries from your
TENS One if the unit is unlikely to be
used for a long period. Some types of
batteries may leak corrosive fluid.
Battery Life
Batteries should last at least 15 hours
(whilst using mode M, 100Hz/50us
(500Ω).
Unused batteries have a nominal shelf
life of 3 years, but will usually last longer
than this.

reach of children to prevent them from
swallowing them by mistake. If
swallowed by child, contact doctor
immediately.
Caution NEVER attempt to
recharge an alkaline battery.
Risk of explosion.
Caution Do not mix old, new or
different types of batteries as
this may lead to battery leakage or low
battery indication.
Disposal: Always dispose of batteries
and device responsibly according to
local government guidelines. Do not
throw batteries onto a fire. Risk of
explosion.
11.2. CONNECTING LEAD
WIRES
You can choose to use one or two lead
wires (two or four electrode pads).
Insert the lead wire plug(s) into the
socket(s) on the top of the unit.
Attaching the electrode pads to the
lead wire.
Push the pin ends firmly into the pigtail
ends of the electrode pads.
The lead wires may be damaged by
rough handling, and should be treated
with care.
Lead wire colour coding
The ends of the lead wires are coloured
black 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.

11.3. PREPARING FOR
SESSION
1) Before use make sure your skin is
clean and dry.
2) Place the electrode pads on the skin,
see section 8.
3) You can use your TENS for several
hours, you can attach the unit to your
belt using the belt clip.
4) You can safely lean on the electrode
pads. The sensation might change.
Warning: Ensure the TENS
One is switched OFF before
applying the electrode pads on the skin.
11.4. TREATMENT SESSION
1) To turn the unit ON, rotate one of the
control knobs clockwise until you
hear a click, the LED indicator will
light up (green colour).
When switched on for the first time,
the TENS One will automatically
select the mode N. Next time, it will
automatically select the mode you
were using the last time it was
switched off.
2) You can select from the 3 preset
modes. Details in section 7 will help
you identify the best mode and
parameters to suit you.
3) With the required mode and
parameters selected, you can adjust
the intensity of the stimulation with
the two rotating control knobs on the
top of the unit until you reach a
comfortable level. The LCD display
shows the strength of intensity used
for each channel.
Note: If the sensation becomes
uncomfortable, reduce the
intensity.
11.5. AFTER YOUR
TREATMENT SESSION
When the timer reaches 0, the display
will flash until the device is manually
switched off.
1) To turn the unit OFF, rotate one of
the control knobs anti-clockwise until
you hear a click, the display will stop.
Then remove the electrode pads
from your skin by holding the pad
itself and gently pulling. Be careful
not to pull the wires as this may
damage them.
2) Replace the electrode pads to their
protective plastic shield and return
them to the re-sealable plastic bag.
Note: When removing the
electrode pads, DO NOT PULL
ON LEAD WIRES.
