2-14 Introducing the NEC MobilePro
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 immediately if the power 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.
Removing and Inserting the Battery Pack
Should you notice the life of a charged battery pack is short,
replace it with a new one. Follow these instructions to replace
a battery pack.
1.
Save your data, turn off unit power, and close the display
panel. Disconnect any cables attached to the unit, such as
the serial cable.
Note:
If you receive messages indicating
that both the main battery and the backup battery
are very low, immediately connect the AC
adapter to charge both batteries.
2.
Have a Lithium-Ion battery pack available.
