15. MAINTENANCE AND CLEANING
The product is maintenance-free. Servicing or repair must only be carried out by a
specialist/specialist workshop. There are no components on the inside of the product
that require maintenance by you. Therefore, you should never open it (apart from the
procedure for replacing the batteries as described in these instructions).
To clean the exterior of the basis station or the outdoor sensor, a dry, soft and clean
cloth is sufficient.
Do not press too hard on the basis station display, as this may cause scratch
marks or lead to faulty displays.
Remove dust on the basis station with a long-haired, soft and clean brush and a vacuum
cleaner.
Use a slightly damp soft cloth to remove stronger contamination from the outdoor
sensor.
Never use any aggressive cleansing agents or other chemical solvents since
this may damage the surface of the casing or even impair operation.
