11. Maintenance and Cleaning

a) General Information
The product requires no servicing apart from replacing the rechargeable battery. Ser-
vicing or repair must only be carried out by a specialist or specialist workshop. There
are no parts that require maintenance by you inside the product. Therefore, never open
it (except for the procedure described in these operating instructions for inserting or
replacing the batteries).
A dry, soft and clean cloth is sufficient for cleaning.
Do not put too much pressure on the display; this can cause scratch marks, failures of
the display or even destroy the display.
Dust can easily be removed with a long-hair, soft and clean brush and a vacuum cleaner.
Never use any aggressive cleaning agents, cleaning alcohol or other chemical solutions,
since these may damage the casing (discolouration) or even impair function.
b) Battery Change
Battery change is required when the display contrast of the basis station or
the outdoor sensors drops strongly. If the batteries are flat, a battery icon will
also appear in the display.
• Follow a battery change of the outdoor sensor with a sensor search at the basis station
if the outdoor sensor is no longer found.
• When changing the batteries in the basis station, all measured values and settings
will be lost.
