HOW TO INSTALL AND REPLACE THE BATTERIES INTO THE THERMO-HYGRO
TRANSMITTER
The outdoor Thermo-hygro transmitter works with 2 x AA IEC LR6, 1.5V batteries. To
install and replace the batteries, please follow the steps below:
1. Uninstall the rain cover of the transmitter.
2. Remover the battery compartment cover.
3. Insert the batteries, observing the correct polarity (see
the marking in the battery compartment).
4. Replace the battery cover and the rain cover onto the
unit.
Note:
In the event of changing batteries in any of the units, all units need to be reset by
following the setting up procedures. This is because a random 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 30 seconds of power being supplied to it.
