7.3.1
Cleaning the touch-sensitive control panel
CAUTION!
It is advisable to use a microfibre cloth to clean the touch-sensitive
control panel.
– Do not use any unsuitable detergents so as to avoid damaging the surface
of the control panel.
– When cleaning, do not apply too much pressure to the control panel in
order to avoid damaging the pressure sensor.
– Never clean the control panel by spitting on it and then rubbing it.
This will cause a smeared film to form on the control panel,
which will have to be cleaned again.
– Never use aggressive or scouring techniques or detergents.
– Never use products which contain ammonia.
Ammonia can damage the control panel.
– Do not spray liquids or water directly onto the control panel.
Otherwise, there is a risk of ingress and damage inside the device.
Spray the liquid onto the microfibre cloth instead and squeeze it out in order
to remove all excess liquid before using it for cleaning.
– Never use paper towels or tissue paper.
They contain wood fibres which can scratch the plastic surface.
Scratches will possibly not be visible initially, but the surface will appear
matt and blurred over time.
The procedure for cleaning is as follows:
1.
Switch off the system before commencing cleaning.
Dirt is easier to see when the device is switched off, and it avoids unintentional
settings as a result of the cleaning action.
2.
Rub the microfibre cloth over the control panel in small circular movements.
You should be able to remove simple dirt this way.
3.
If stubborn dirt persists, dampen a cotton cloth with distilled water and repeat the
cleaning process, once again rubbing it with small circular movements.
4.
Finally, rub it once again with the microfibre cloth until no visible dirt remains.
ENVIRONMENT!
Risk of environmental damage due to incorrect disposal!
Incorrect disposal can be a threat to the environment.
Detergents and accessories (brushes, cloths, etc.) must be disposed of in
compliance with local regulations and with due regard for the information
displayed on cleaning containers and on the safety data sheets
provided by the manufacturers.
