Note:
In the event of changing batteries in any of the units, all units need to be reset by
following the setup 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
Temperature Station in the first few minutes of power supplying.
BATTERY CHANGE:
It is recommended to replace the batteries in all units regularly to ensure optimum
accuracy of these units. (Battery life –see Specifications)
