10. REMARKS ON OPERATION

10.1. The treatment head: a precision
instrument
A treatment head is a precision instrument. Great care
is taken in the development and production in order
to obtain the best possible beam characteristics.
Rough treatment (jarring or dropping) can adversely
affect these characteristics, and must therefore be
avoided.

10.2. The contact medium

In order to ensure efficient transfer of energy, a
contact medium is required between the treatment
head and the body. Air causes virtually total reflec-
tion of the ultrasound energy. The best medium for
the transfer of ultrasound energy is a gel.
• For preference, use Enraf-Nonius Contact-Gel
as this allows the excellent characteristics of the
treatment heads to be used to their full advan-
tage.
• The gel should be applied to the part of the body
to be treated and then spread out with the treat-
ment head.
• Never apply the gel to the treatment head.
The treatment head will register this as con-
tact and may emit ultrasound energy, which
could damage the treatment head.
If the body surface is very irregular, making it diffi-
cult to obtain good contact between the treatment
head and the body, or if direct contact must be
avoided (e.g. due to pain), the affected area may
be treated under water (subaqual method). The
water should be degassed (by previous boiling) in
order to prevent air bubbles arising on the treat-
ment head and the body.

10.3. Contact control at incomplete contact

When the treatment head only contacts partially
with the body, the treatment is interrupted.
When not enough surface of the treatment head
makes contact with the patient the treatment is in-
terrupted (= contact control). The intensity display
starts flashing (and/or a sound signal is audible if
turned on) and the treatment time is interrupted.
The contact control does not function at a set in-
tensity of 0,1 and 0,2 W/cm².

11. MAINTENANCE BY THE USER

11.1. Apparatus

Before performing any user maintenance, switch
off the apparatus and disconnect the plug from the
mains supply. The apparatus can be cleaned with
a damp cloth. Use lukewarm water and a non-abra-
sive liquid household cleaner (no abrasive, no al-
cohol content solution).

11.2. Treatment head

The treatment head and cables should be regularly
inspected for damage, e.g. hairline cracks, which
could allow penetration by liquids. Clean the contact
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 head can be disinfected using a cloth
moistened with 70% alcohol.

11.3. Environment Information

Your Sonopuls 190 contains materials which can
be recycled and/or are noxious for the environment.
At the end of the duration of life, specialised con-
cerns can take apart the Sonopuls 190 and sort
out the noxious materials and materials for recy-
cling. By doing so you contribute to a better envi-
ronment.
Please ensure that you are well informed of the
local rules and regulations regarding to the re-
moval of equipment and accessories.

12.1. Display's fail to light up

Check if the mains adapter is connected to the unit
and mains supply.
12.2. Error code ErX* on the duty cycle
display
The unit has discovered a fault using its "self-test".
Switch the unit back on. If the code re-appears,
contact your supplier. The unit is probably defec-
tive.
* ErX: number 1/9 is mentioned on position X

12.3. The contact control fails to operate

• Check the contact control by placing the treat-
ment head in a bowl of water. It may be that the
contact control is working, but that the contact
gel is inadequate.
• An intensity of 0.1 or 0.2 W/cm² is used.
