INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER
The Temperature Transmitter uses 2 x AA, IEC LR6, 1.5V battery. 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: 
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 Clock in 
the first 3 minutes of power being supplied to it. 
 
BATTERY CHANGE:
It is recommended to replace the batteries in all units regularly to ensure optimum accuracy 
of these units (Battery life See Specifications below).
