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 sensor at start-
up and this code must be received and stored by the Weather Station 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).
Please participate in the preservation of the environment. Return used batteries
to an authorized depot.
