15. Maintenance and cleaning
15.1. General
Check the technical safety of the product regularly, e.g. damage to the
housing.
If it can be assumed that the device is not safe for operations, switch
the device off, and secure against inadvertent switching on. Remove the
batteries.
You can assume that the device is not fit for use if
• the device shows visible damage
• the device is no longer functional
• after extended periods of storage in unfavorable conditions
• after transportation in unfavorable conditions
Observe the following safety instructions before cleaning or servicing
the device:
Remove the batteries before cleaning, servicing or repair
work.
There are no user-serviceable parts on the inside; do not open
the device.
Repairs may only be carried out by a specialist who is familiar
with the associated hazards and relevant regulations applying
to the device.
15.2. Cleaning base station
Dust can be removed very easily with a vacuum cleaner and a soft, clean
brush. Hold the vacuum cleaner nozzle close to the base station (avoid
touching the base station as this may cause scratching!) and remove
the dust with the brush. The dispersed dust will be sucked in by the
vacuum cleaner. Use a soft, dry, lint-free cloth to clean the exterior of
the product.
In case of heavy soiling, you can use a cloth slightly moistened with
warm water.
Never use aggressive cleaners or chemical solutions as this could damage
the surface of the device or impair its functionality.
