2-14 Introducing the NEC MobilePro
!
CAUTION
The MobilePro’s internal data backup battery
provides power to maintain the memory contents
for a limited period of time when the main battery
is removed and the unit is not connected to an
AC power source. The backup battery does not
provide sufficient power to operate the system.
Do not remove the main battery from the unit for
an extended period of time unless the unit is
connected to an AC power source. The backup
battery is not user replaceable.
Battery Replacement
Note the following when replacing batteries:
If the main battery becomes weak, the MobilePro
automatically turns off. Recharge or replace the main
battery imme d iately if the p ower goes off.
The MobilePro has a built-in backup battery that maintains
your data for several hours whenever the main battery is
depleted or removed. The backup battery is recharged
whenever the unit is connected to an AC power source.
If you fail to replace a depleted main battery for an
extended period of time and the back-up battery is weak,
the contents of the MobilePro memory and all user data
may be lost.
