8.1 Buffer battery
The device has a lithium manganese dioxide battery, type CR2032, to buffer the
memory. The battery is on the rear of the terminal housing.
The buffer battery must be replaced by a new one every 2 years.
NOTICE!
Immediate data loss in the absence of buffering
If the battery is removed, with the terminal switched off, or if the battery is already
empty at the time of switch-off, booking records, master records, profiles and the
parameter setting will get lost immediately.
In this case, following the battery replacement, a cold start must be carried out, and
then the data must be transferred again to the terminal.
• Save all data, before switching off the terminal.
• Perform the battery change with the unit switched on.
To do so, use a PoE power injector, e.g., 04042778, for supplying power to the
terminal. This injector must remain connected to the network connector of
the terminal for the duration of the battery change.
