INSTALL AND REPLACE BATTERIES IN THE OUTDOOR TRANSMITTER
The thermo-hygro transmitter uses 2 x AAA, IEC LR3, 1.5V batteries. When batteries need
to be replaced, the low battery icon will appear on the OUTDOOR section of the LCD.
To install and replace the batteries, please follow the steps below:
1. Remove the battery compartment cover at the back of the transmitter.
2. Insert the batteries, observing the correct polarity (see marking).
3. Replace the battery compartment cover on the unit.
Note: When changing batteries in any of the units, all units need to be reset by following
the setting up procedures. This is because a security code is assigned by the transmitter at
start-up and this code must be received and stored by the weather station in the first 3
minutes of power supplied to it.
