4 MAINTENANCE
NOTE
Rechargeable backup batteries and battery packs are not
initially charged. Therefore the initial operation to perform is
to charge them. See below.
CAUTION
By default, the backup battery is disconnected at the factory
to avoid damage due to excessive draining. If it is not
connected (through the backup battery switch) and
subsequently charged together with the battery pack, all
data will be lost when changing the battery pack.
Annual replacement of rechargeable battery pack avoids
possible risks or abnormalities and ensures maximum
performance.
4.1 CONNECTING THE BACKUP BATTERY
The backup battery must be connected by putting the switch in the "connected"
position. It will be charged together with the battery pack through the normal
charging process.
It is only necessary to disconnect the backup battery if it will not be used for a
long period of time (i.e. several weeks).

DISCONNECTED
CAUTION
Be careful when using sharp-edged tools to move the
switch from the “disconnected” position to the "connected"
position and vice versa!
