Nec MOBILEPRO POWER SYSTEM User Guide

Introduction to Your

MobilePro Power System

Congratulations on purchasing the NEC MobilePro™ Professional PC
Companion powered by the Microsoft® Windows® CE operating system.
The portability and capabilities of this device, including instant-on and
easy synchronization to your PC, allow you to keep your most important
business and personal information up-to-date and close at hand.

Be sure to read the contents of this document for information about
maximizing the device’s power capabilities.

CAUTION

If you power off, then quickly power on the NEC
MobilePro, your system may erroneously report the
presence of PC cards and/or CompactFlash cards.

In addition, quickly pressing the POWER key several
times in a few seconds (repeatedly powering the unit
off and on), may cause PC card and/or CompactFlash
card data loss. NEC recommends that you wait ten
seconds after powering off, before powering on the
NEC MobilePro.

Windows CE Operating System

The Windows CE operating system and pre-loaded applications are stored
on a Read-Only Memory (ROM) module. ROM modules are electronic
circuits that cannot crash. Files cannot be added or deleted from ROM, by
a user, and removing power from your MobilePro unit has no adverse
effect on ROM storage.

Additional program applications and files that you add to your MobilePro
are stored in Random Access Memory (RAM). The RAM in your
MobilePro is protected when the unit is running on battery power or
plugged into an AC power source. To ensure the safety of your data and
user installed software, please carefully follow the battery charging
instructions.

Introduction to Your MobilePro Power System 1

Using MobilePro’s Power Sources

The MobilePro is powered by one of two power systems: battery power
(main and backup batteries) or AC power.

Connect your MobilePro to a standard 110 volt AC socket using the AC
adapter that ships with your unit. The battery systems recharge when the
unit is connected to an AC power source.

CAUTION

Use only the MobilePro 880 battery (MC/BA11A) in the
MobilePro 880 system (MC/R730A). Do not use the
MobilePro 800 battery (MC/BA11) in the MobilePro
880 system. Use of the MobilePro 800 battery in the
MobilePro 880 system may cause battery damage
and/or system data loss.

Note: Before using the system for the first time,

allow ten hours for both the main and the backup
batteries to fully charge, even if the indicator on the
front of the MobilePro lights green before the full ten
hours are passed. You must repeat this full ten hour
charge cycle, only if the backup battery becomes fully
discharged.

To protect your data, do not use the system until the
backup battery is charged. Recharge the battery
whenever the battery charging LED lights amber.

Main Battery

The main battery is a rechargeable Lithium-Ion battery pack that provides
power to operate the unit when it is not connected to an AC power source.
It is advisable to operate the unit on AC power, whenever possible, to
maintain a fully charged main battery, ready for mobile operation.

Do not remove the main battery from the MobilePro unit for an
extended period of time.
