Batteries

Your CASSIOPEIA is powered by a dual power supply that consists of a main battery (rechargeable battery pack) and a backup battery (CR2032 lithium battery).

We recommend that you use the Power dialog box to keep informed about the current levels of your main and backup batteries. See the separate Pocket PC User’s Guide and Pocket PC online help for more information about this dialog box.

Icons appear in the Taskbar to let you know when battery power is low. See the separate Pocket PC User’s Guide for more information about these icons.

Important

The following messages appear whenever battery power drops below a certain level.

Main Battery

Recharge the battery pack as soon as possible after the following message appears.

“Main Batteries Very Low

To prevent possible data loss, replace or recharge your main batteries according to the owner’s manual.”

Backup Battery

Replace the backup battery as soon as possible after the following message appears.

“Backup Battery Very Low

To prevent possible data loss, replace or recharge your backup battery according to the owner’s manual.”

Data stored in memory can be lost if you continue operation after the low battery message appears or if you incorrectly load batteries. Be sure to always back up important data on your desktop computer hard disk or on a CompactFlash memory card. See ActiveSync help for information about backing up files to a desktop computer.

See the Card Backup Tool manual (PDF file) on the CASSIOPEIA Application CD- ROM for information about backing up data to a CompactFlash memory card for information about using the Card Backup Tool program to back up data to a CompactFlash memory card.

Never remove the main battery and backup battery from the CASSIOPEIA at the same time. Doing so causes all data stored in memory to be deleted.

Should the main battery and the backup battery both require replacement, be sure to always replace the main battery first.

Use the rechargeable battery pack for the main battery and a CR2032 lithium battery for the backup battery. Never use any other type of batteries.
