Using Batteries 2-3
Charging the Backup Battery
The internal backup battery is a 3.6-volt lithium-ion battery that maintains
the printer’s system settings. The backup battery maintains its charge
through the main battery or the Battery Backup Power. When fully
charged, the backup battery provides seven days of power. To keep the
battery fully charged, connect the Battery Backup Power whenever you
remove the main battery.
Note: If the printer does not have a main battery or is not connected to
the Battery Backup Power, it loses its charge and the printer’s
system settings.
1. Remove the main battery from the
battery compartment.
2. Connect the Battery Backup Power as
shown.
3. Plug the other end into a grounded
electrical outlet.
The LED at the top left of the
keypad blinks amber when the
Battery Backup Power is properly
connected.
