6.1. Technical maintenance

Electrical safety of the apparatus depends on the
electrical connection (via the power cord) to protec-
tive earth. It is therefore necessary to have this con-
nection checked annually. Further an annual overall
check is recommended. This may be done by your
supplier, or by another agency, authorised by the
manufacturer. It is also recommended that a record
of the service history is kept for all activities relating
to service and maintenance. In some countries this
is even obligatory.
Maintenance and all repairs should only be carried
out by an authorised agency. The manufacturer will
not be held responsible for the results of maintenance
or repairs by unauthorised persons.
The service and/or maintenance must be carried out
conform the procedure described in the service
manual of the apparatus.
Opening of the equipment by unauthorised agen-
cies is not allowed and will terminate any claim to
warranty.

6.2. Cleaning of the apparatus

Switch off the apparatus and disconnect it from the
mains supply. The apparatus can be cleaned with a
damp cloth. Use lukewarm water and a non-abrasive
liquid household cleaner (no abrasive, no alcohol
content solution).

6.3. Cleaning of accessories

6.3.1. 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.
Damaged 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 saline
solution to improve the conductivity of the water.
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.

CHAPTER 6 - MAINTENANCE

6.3.2. Treatment heads

The treatment heads and cables should be regularly
inspected for damage, e.g. hairline cracks, which
could allow penetration by liquids. Clean the con-
tact surface immediately after each treatment. Make
sure that no ultrasound gel remains on the treatment
head. We further recommend cleaning the head and
cable daily, using lukewarm water.
The treatment heads can be disinfected using a cloth
moistened with 70% alcohol.

6.3.3. Patient cable

The patient cable can be cleaned with a damp cloth.
Use lukewarm water and a non-abrasive liquid house-
hold cleaner (no abrasive, no alcohol content solu-
tion). Check the cable regularly for damages and/or
bad electrical contact. We also advise that you keep
an extra patient cable in stock.

6.4. Environment information

Your Sonopuls 492 contains materials which can be
recycled and/or are noxious for the environment. At
the end of the duration of life, specialised concerns
can take apart the Sonopuls 492 and sort out the
noxious materials and materials for recycling. By
doing so you contribute to a better environment.
Please ensure that you are well informed of the
local rules and regulations regarding to the re-
moval of equipment and accessories.
