16 Connecting remote sensors

The Weather Station can display the readings from up to 3 wireless sensors of the same type. Each
radio sensor must be set to a separate channel. Proceed as follows to set the channel:
1. Remove the battery compartment cover of the wireless sensor.
2. Set the channel selection switch to the desired channel (CH1, CH2 or CH3).
3. Re-attach the battery compartment cover.
4. NOTICE! Each connected wireless sensor must be set to a different channel. If only one wire-
less sensor is connected, it should be set to CH1.
5. Press CHANNEL button for about 3 seconds to reset the values and search for a wireless sensor
(RF signal).

17 Display brightness regulation

1. When using battery power, press the SNOOZE/LIGHT button to activate the display for about 7
seconds.
2. In mains operation (DC 5V), touch the SNOOZE/LIGHT touch surface several times to set the de-
sired display brightness in steps: dim - bright - off
3. NOTE! It is not possible to adjust the display brightness in battery operation.
