Mobilepro Power Management; Battery Replacement - NEC MOBILEPRO 780 User Manual

MobilePro Power Management

When your MobilePro is connected to an AC power source
and the main battery is removed from the system, be sure
to replace the main battery before disconnecting the AC
adapter to prevent possible data loss.
The MobilePro's internal data backup battery pro-
vides power to maintain the memory contents for a
limited period of time when the main battery is re-
moved and the unit is not connected to an AC power
source. The backup battery does not provide suffi-
cient 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 auto-
matically turns off. Recharge or replace the main
battery immediately if the power goes off.
!"
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 re-
charged whenever the unit is connected to an AC power
source.
!"
If you fail to replace a depleted main battery for an ex-
tended period of time and the back-up battery is weak,
the contents of the MobilePro memory and all user data
may be lost.
