Electrodes and sponge pads
The rubber electrodes should be cleaned with luke-
warm water. For stubborn stains or dirt, cleaning and
disinfection of the rubber electrodes can be done
using a 70% alcohol solution. During this process,
the black colouration of the rubber electrodes may
be stained. This does not affect the operation of the
electrodes.
The sponge pads must be washed after use in warm
water with a household cleaner. Then they must be
rinsed with water, drained thoroughly and then dried,
after they have been placed like roofing tiles. Dam-
aged sponge pads must be replaced.
In areas where the water is soft, it is possible that
the water may conduct poorly resulting in abnormally
low currents. In this case it is possible to use a sa-
line solution to improve the conductivity of the wa-
ter.
When the electrodes are not being used, the sponge
pads should be removed. This increases the opera-
tional life of the rubber electrodes. We advise that
you should keep an extra set of sponge pads in stock.
Patient cable
Check the cable regularly for damages and/or bad
electrical contact. We also advise that you keep an
extra patient cable in stock.

Environment Information

Your Sonopuls contains materials which can be re-
cycled and/or are noxious for the environment.
At the end of the duration of life, specialised con-
cerns can take apart the Sonopuls and sort out the

FAULT CONDITIONS

Lamps and display fail to light up
• The battery is possibly exhausted. Try to use the
Sonopuls with the batterycharger connected to
the mains supply.
Error message "Error code ..." on the display
The unit has discovered a fault using its "self-test".
Remove any applicators or cables from the output
sockets from the equipment, switch the unit back
on. If the code re-appears, contact your supplier. The
unit is probably defective.
The contact control fails to operate
Check that the treatment head has been selected.
Check the contact control by placing the treatment
head in a bowl of water. It may be that the contact
control is working, but that the contact gel is inad-
equate. If several treatment heads are available, it
is possible to determine whether the problem lies in
the gel, the treatment head or the unit itself.
Insufficient or no output current
• Check the patient cable for breaks or poor con-
tact.
• Ensure that the sponges are sufficiently damp.
• If necessary, use a salt solution.
• Clean the electrodes and check for poor contact.
• In combination therapy, the maximum output cur-
rent for two-pole interferential therapy is limited
to 60 mA.
