b) Inserting batteries in the outdoor sensors
First open the battery compartment and set the transmission channel and
temperature unit for the display shown via the DIP switches; see above.
• Insert 2 type AAA/Micro batteries into each outdoor sensor in the correct polarity
(observe plus/+ and minus/-).
• Right after inserting the batteries, the outdoor sensor will briefly display all display
segments. If only chaotic characters appear in the display, take out the batteries for
a few seconds and insert them again.
• Close the battery compartment again. For this, put on the battery compartment lid
properly and screw it on.
• The display shows the channel number (24). It will later be used to assign the indica-
tion in the display.
At each transmission process of the outdoor sensor (the measuring data are
transmitter in this), the red LED (23) at the front of the outdoor sensor will flash
briefly.
