Battery
In the event of a power failure, the battery provides the electricity to prevent loss of the stored date, time
and programming. When the power supply is switched back on, the stored data is retrieved and the
device continues to operate as normal.
If the device is operated on the battery for more than 30 days, the data have to be reprogrammed.
