1. How will these instructions help you?
Warning!
This symbol warns you about possible
damage to your health.
NB!
This symbol draws your attention to
possible damage to your appliance.
Note
This symbol draws your attention to particularly
useful information about using your appliance.
The important parts of your appliance are marked with
numbers.
Using these part numbers, you can safely identify the
displays and controls whose significance and use we explain
in this manual.
2. Background information
2.1 What is pain?
Acute pain (protective pain) is a natural warning system which draws our
attention to the fact that something is wrong with our bodies. Acute pain helps
us to recognise the early onset of disease and to treat it.
Chronic pain is not a natural condition. It occurs as the result of a fault in the
affected nerve cells and no longer functions as a warning.
Chronic pain is persistent, recurrent pain that lasts for longer than 3 – 6
months. Chronic pain occurs irrespective of its original cause – the original
cause either no longer exists or can no longer be remedied.
2.2 What is TENS?
TENS, Transcutaneous (delivered via the skin) Electrical Nerve Stimulation,
is a valuable method in the treatment of pain. TENS blocks the transmission
of pain signals to the brain. The patient is no longer aware of the pain or is
less aware of it.
3. The Well TENS
The Well TENS produces electrical pulses: you can adjust the intensity, rate
(frequency) and amplitude of these pulses to suit your own particular treatment
requirements.
27
Self-adhesive electrodes are stuck onto the skin and conduct the electrical pulses
into the nervous system in the area being treated. These stimulations are not
painful. You will only feel a gentle prickling or vibration on the skin.
The Well TENS has two independently controllable output channels and
offers you a choice of three TENS operational modes.
Particular advantages of the Well TENS:
■ Easy to use at home or away
■ Freedom to move whilst using the appliance
■ Always available
■ No known side effects when used as intended.
4. Your safety is important to us
Please read these instructions carefully before using your Well TENS for the
first time. They cover all you need to know in order to operate your Well TENS
safely and avoid damage.
This instruction manual is an important part of your purchase. Keep it safe –
until you either pass on your Well TENS with these instructions to a new owner
or finally dispose of the appliance.
4.1 For what range of use is the Well TENS suitable?
► We recommend that you consult your doctor or physiotherapist
before using the Well TENS.
► Your doctor or therapist will help you decide on your course of
treatment and to monitor its progress.
► The Well TENS is only intended for external use on human
beings.
► The Well TENS may only be used as described in this
instruction manual.
4.2 For what range of use is the Well TENS unsuitable?
Danger of sparking and explosion!
The Well TENS does not have AP/APG protection. Do not place the
Well TENS near highly inflammable materials, highly inflammable
gases or explosives.
Electromagnetic radiation!
The Well TENS can interfere with electronic monitoring equipment
such as ECG monitors and ECG alarms. Do not place the Well TENS
near machines of this type.
4.3 For what areas of application is the Well TENS suitable?
► The Well TENS is only suitable for the treatment of chronic pain
which has been diagnosed as such without doubt.
28
► Treatment with the Well TENS has no effect on non-specific pain
such as non-specific headaches.
4.4 For what areas of application is the Well TENS unsuitable?
► Treatments with the Well TENS are of a purely symptomatic
nature. They cannot bring about any healing.
Do not use the Well TENS
● if the patient suffers from allergic skin reactions.
Self-adhesive electrodes may lead to irritation of the skin.
● if the patient suffers from heart problems, in particular
cardiac dysrhythmia. The stimulation current may lead to
ventricular fibrillation and in the worst case scenario to
cardiac arrest.
● if the patient has a heart pacemaker, other electronic
implants or metallic implants. The stimulation current may
interfere with the function of the implant.
● if the patient suffers from convulsive disorders. In the worst
case scenario the stimulation current may cause convulsive
seizures.
● if the patient is pregnant. In the worst case scenario the
stimulation current may cause premature contractions.
● during menstruation.
In the worst case scenario the stimulation current may
increase the amount of bleeding and cause or aggravate
cramps.
● on areas of the skin in which the patient no longer has any
sensation of pain. Self-adhesive electrodes may lead to
irritation of the skin and burns.
● if the patient suffers from systemic diseases (i.e. those
affecting the whole body).
4.5 Other points to consider

9. Carrying out treatment
9.1 What you need to take into account when carrying out treatment
► Keep to the treatment plan recommended by your doctor or
therapist.
► Stop the treatment immediately if it starts to become unpleasant
and consult your doctor or therapist.
► Stop the treatment immediately if it has had no effect following a
treatment session of the length agreed with your doctor or thera
-
pist, and consult your doctor or therapist.
► Stop the treatment if after long-term usage the skin becomes
irritated at the points where the self-adhesive electrodes are applied. Only continue with the treatment once you have checked
the cause of the skin irritation with your doctor or therapist.
9.2 Where should you not attach the self-adhesive electrodes?
► Do not attach the self-adhesive electrodes to the eyelids.
The stimulation current may damage the eye.
► Do not attach the self-adhesive electrodes to the mouth, larynx
or throat area. The stimulation current can lead to muscle
cramps and thus to suffocation.
► Do not attach the self-adhesive electrodes to the area of the
carotid sinus (the area at the front of the neck over the carotid
sinus nerve). In patients with a sensitive carotid sinus reflex the
stimulation current may result in cardiac arrest.
► Do not attach the self-adhesive electrodes to the inside of the
mouth or in the immediate vicinity of the heart. The stimulation
current could flow directly via the heart and cause ventricular fibril
lation or even cardiac arrest.
► Do not attach the self-adhesive electrodes in such a way that
the current passes directly through the brain, e.g. on both temples. The stimulation current may set off convulsive seizures.
9.3 Where can you attach the self-adhesive electrodes?
The correct positioning of the self-adhesive electrodes is an impor-
tant factor for successful treatment.
► Follow the instructions of your doctor or therapist precisely.
► As a rule, the self-adhesive electrodes are positioned directly
over the painful area or in its immediate vicinity. It is also
possible to encircle the painful area with four self-adhesive
electrodes.

9.4 How to carry out treatment
During treatment you should keep a minimum of 1 m away from microwave
and short wave appliances. Electromagnetic interaction may affect the
functioning of the Well TENS.
1. Use scissors to cut off any lush growth of hair at the points where you want
to apply the self-adhesive electrodes as recommended by your doctor or
therapist.
Do not shave the areas concerned.
2. Use a mild soap solution to clean the skin at the points where you want to
apply the self-adhesive electrodes. Rinse off the soap solution well and
dab the skin with a towel until it is thoroughly dry.
3. Connect the two-way adaptor of the self-adhesive electrodes with the
two-way adaptor at the end of the supply cable.
According to what your doctor or therapist recommends, you may also
carry out treatment using just one pair of electrodes. In this case make
the connections for this one pair of electrodes only.
Do not touch the self-adhesive electrodes unless both channels of
the Well TENS are switched off. The strong current may cause an
unpleasant sensation on the small area of the finger.
4. Remove the self-adhesive electrodes from the protective film.
Always pull the self-adhesive electrodes by the plaster and never
by the wires. The wires may break if subjected to too much
mechanical stress.
5. Stick the self-adhesive electrodes onto the contact points recommended
by your doctor or therapist.
Do not overstretch the skin when you stick on the electrodes. Lay the
self-adhesive electrode lightly onto the skin and then press the electrode
gently from the centre to the outside.
The self-adhesive electrodes must adhere firmly to the skin.
Replace with new self-adhesive electrodes when the adhesive has become weak.
6. Connect the supply cable to the output jack on the Well TENS appliance
36
Insert the plug into the output jack as far as it will go.
7. Switch on Channel 1 and Channel 2 of the Well TENS by rotating the left
and right on/off knobs clockwise until you hear a click. The LED displays
will light up.
NB: Make sure that the current settings are as specified by your
doctor or therapist.
8. Set the intensity for Channel 1 and Channel 2 by turning the left and right
on/off knobs slowly clockwise until the stimulation reaches a pleasant level
of intensity.
9. Reduce the pulse intensity or switch off the Well TENS
if you begin to find the stimulation unpleasant.
10. Ending the treatment:
When the treatment duration as set has expired, the stimulation will cease
automatically and the LED displays on the Well TENS will go blank.
Switch off Channel 1 and Channel 2 of the Well TENS by turning the left
and right on/off knobs anticlockwise until you hear a click. The LED
displays will go blank.
11. Remove the self-adhesive electrodes from the skin by pushing a fingertip
under each electrode and lifting it off in the direction of the hair growth.
37
Always pull the self-adhesive electrodes by the plaster and never by
the wires. The wires may break if subjected to too much mechanical
stress.
12. Stick the self-adhesive electrodes back onto the protective film and store
them in the re-sealable bag until the next treatment session.
13. Rub a little body lotion onto each point on the skin where the self-adhesi
ve electrodes were fixed, if needed.
14. Put the Well TENS and the accessories back into the storage case
15. Store the Well TENS in a safe place out of the reach of children and away
from direct sunlight and damp until the next treatment session.

10. Setting up the Well TENS
10.1 Setting the operating parameters
We recommend that you consult a doctor or therapist with regard to the
setting of your treatment parameters, including pulse rate, pulse width and
pulse strength.
For the treatment to work successfully it is necessary for the patient to
experience a noticeable tingling feeling or vibration on the skin. If the success
of the treatment begins to wane after a time because the body accustoms itself
to the current settings, the doctor or therapist must re-check and re-set the
treatment parameters. In such a case it may be sensible also to change the
operating mode, i.e. select a modulated operating mode.
1. Open the faceplate.
2. Set the mode:
Move the sliding switch to select one of the three possible operating
modes:
Mode Meaning Function
B

of the default setting, remains at the lower level for 2
seconds, returns to the default setting and remains at
the default setting for 3.5 seconds. One cycle lasts
5.5 seconds. The pulse rate, width and strength are
adjustable.
38
All the following settings apply automatically to all three operating
modes.
3. To set the pulse width, turn the pulse width selection dial until it reaches
the desired setting.
4. To set the pulse rate, turn the pulse rate selection dial until it reaches the
desired setting.
