13. Maintenance and cleaning
a) General
Check the technical safety of the product regularly, e.g. damage to the housing.
It can be assumed that operation is no longer ensured without risk if
• the device shows visible damage
• the device is no longer functional
• after longer periods of storage under unfavourable conditions or
• after heavy transport stress
Before cleaning or servicing the device, observe the following safety instructions without
fail:
Remove the batteries before cleaning, servicing or carrying out repair work.
There are no parts in the interior requiring servicing; the device may not be opened.
Repairs may only be carried out by a specialist who is familiar with the associated
hazards and relevant regulations for the device.
b) Cleaning base station
Dust can be removed very easily with a vacuum cleaner and a clean, soft brush. Keep the opening
of the vacuum cleaner close to the base station (do not come into contact, scratching possible!)
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 for cleaning the exterior of the product.
For greater contamination, you can use a cloth slightly moistened with warm water.
Never use aggressive cleaners or chemical solutions as the surface of the device or its functionality
could be damaged as a result.
c) Cleaning outdoor sensors or combination sensor
After a longer period of operation in the open air, dirt can gather on the plastic surface of the
outdoor sensors.
This can be removed very readily with a soft cloth which has been moistened with water.
Never spray the outdoor sensors with, for example, a garden hose as the outdoor
sensors are only protected against rain from above and not against water jets from
the side or from below.
The rain gauge should be monitored from time to time.
