12. Operating the indoor/outdoor sensors
a) Searching for sensors
If only lines appear in a display field (e.g. for the rain sensor: "- - - . -"), you can start a manual search for all outdoor
sensors.
For this purpose, keep the button " " (16) on the rear depressed until the symbol for the radio reception of the
outdoor sensors blinks on the top of the display.
The sensor search may take a few minutes.
If one of the sensors is not found, check its batteries, place the sensor in a different location and reduce the distance
between the weather station and the sensor.
b) Background illumination
When using the provided power pack unit, the background illumination can be activated permanently (or it is activated
automatically at darkness and deactivated during the day).

With battery operation, the background illumination can only be activated briefly to save energy and
battery power.
You can select the desired function with the switch "LIGHT SENSOR" (11):
ON The background illumination is always on (only when using the provided power pack unit).
OFF The background illumination is off and only activated for a few seconds when briefly pressing the button
"LIGHT".
AUTO The background illumination is activated at darkness and deactivated during the day.
The sensitivity for the brightness detection (and therefore the automatic activation/deactivation of the background
illumination) is selected with the switch "SENSITIVITY" (12). Two positions are possible ("HIGH" and "LOW").
