8. Installation
The outdoor sensor can be easily installed on a vertical surface with the
enclosed installation base.

Please observe:
Chose an installation site that is not immediately subjected to
direct precipitation, strong dust impact or direct sunlight.
A roof overhang, for example, is suitable for external installation.
Observe the following drawing for the installation. Screw the installation base
onto a vertical surface with a matching screw (use a matching dowel, if
applicable).

The notches in the casing must point upward (see drawing).
Make sure that no electric cables, gas or water pipes run along the
installation site that may be damaged by the screw. Mortal danger!
After installation, slide the outdoor sensor into the installation base.
When you want to take the outdoor sensor off (e.g. when changing the
batteries), carefully pull the outdoor sensor forward out of the installation base.
