Radio sensor
1. Remove the battery compartment lid on the back of the radio
sensor.

Using additional radio sensors
The weather station is supplied with one radio sensor. However, you
can operate the weather station with up to three radio sensors. Addi-
tional radio sensors are available through our Service centre, see
page 46.
z The radio sensors can be situated in different rooms or outdoors.
z Each sensor must have its own sensor number (sensor number =
number of the transmission channel) allocated to it (1 to 3).
z For the snow and frost warning, the weather station only evalu-
ates the data of the sensor with the lowest number (default is 1).
