Maintenance, cleaning, care and adjustment
Only clean the product using a soft, lint-free cloth that is clean and dry.
You may dampen the cloth a little with lukewarm water in order to remo-
ve more stubborn marks. Make sure that no moisture will ingress into the
housing. Do not use any detergents containing solvents, as they could
corrode the plastic housing and label.
Check that your product is safe from a technical point of view (that
the housing is not damaged, for example) on a regular basis. If
you have reason to believe that it is no longer safe to operate the
device, put it out of service. Remove the battery pack to safeguard
the device against unintentional operation.
Safe operation may no longer be possible if the device
•
shows sings of external damage,
•
no longer functions,
•
has been stored a longer period under unfavourable conditions or
•
has been subject to severe transport conditions.
If not used for any length of time (e.g. when in storage) remove
the batteries to avoid damages caused by leaking.
6.1 Cleaning the rain sensor
Depending on the location, leaves, dirt particles transported by the wind,
sand, branches, etc., may get into the rain sensor’s collecting funnel
(G)
.
Larger items may block the flow of rainwater. Sand can also accumulate
in the counter rocker: as the amount increases, this causes the measure-
ment results to be less accurate.
Consequently, the rain sensor must be cleaned from time to time; this
must be done at least once a year, however.

The collecting funnel
(G)
of the rain sensor
(H)
can be detached
from above by turning it slightly clockwise.
•
The cap of the rain sensor
(H)
can also be detached by turning it
slightly clockwise and pushing it down.
•
The rain sensor can now be detached from above and moved to
the side with the cable. Remove the counter rocker.
