Recharging the Backup Battery

The backup battery charges while the main battery is charging. It usually takes approximately 4.5 hours to recharge both the main and backup batteries together.

A full 10 hours charging time is required under either of these circumstances:

!This is the first time you have used your MobilePro

!The main battery has been in a depleted state for a prolonged period.

In these cases allow 10 hours for both the main and backup batteries to charge, even if the LED indicator on the front of the MobilePro lights green before the full 10 hours have passed.

To protect your data, do not use the system until the backup battery is charged.

To recharge the main and backup batteries, connect the AC adapter. See the section, “Connecting the AC Adapter” in Chapter 1.

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 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.
