11. Maintenance and Cleaning
a) General
Check the technical safety of the weather station, such as damage to the housing, at regular
intervals.
When it can be assumed that a safe operation is no longer possible, the product must be put
out of service and precautions taken to ensure that it is not used unintentionally. Remove the
batteries.
It must be assumed that safe operation is not possible any longer, if
• the station is visibly damaged,
• the device does not operate any longer and
• it has been stored for long periods under unfavourable conditions or
• it has been subject to considerable stress in transit.
The safety instructions below must be observed before the weather station is cleaned or
maintained:
Before cleaning, servicing or repair works, the batteries must be removed.
None of the components inside the station is to be maintained by the user. The hous-
ing must not be opened.
Repair work must always be carried out by qualified experts familiar with the hazards
involved and with the relevant regulations.
b) Cleaning the Multipurpose Sensor
After a longer period of operation in the open, dust can deposit at the plastic surface of the
outdoor sensors. It can be removed rapidly with a cloth slightly moistened in water.
Never use a garden hose to clean the outdoor sensors, because they are only pro-
tected against rain coming from the sky above but not against jets of water coming
from the sides or below.
