Main Battery and Backup Battery
Your CASSIOPEIA uses two types of batteries for power: a rechargeable user-replaceable rechargeable
battery pack for the main battery, and a button type lithium battery for memory backup.
• We recommend that you use the Power Properties 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 properties.
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
Charge the battery pack as soon as possible after the message shown below appears on the display of
the CASSIOPEIA. Charging the battery pack also charges the memory backup battery.
"Backup Battery Very Low
To prevent possible data loss, replace or recharge your backup battery according to the owner's
manual."
• You can monitor the current battery power level accessing Power Properties or by checking the
battery icon in the command bar of the Today screen.
• Whenever the low battery warning message appears, especially if it appears right after you turn on
power, follow the instructions that appear on the screen and replace batteries as soon as possible.
Continued use under low battery power can cause unstable performance of your Pocket PC.
• 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 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 CD-ROM for information about
backing up data to a CompactFlash Card for information about using the Card Backup Tool
program to back up data to a CompactFlash Card.
• Never remove the battery pack from the CASSIOPEIA while memory backup battery power is low.
Doing so can cause a loss of data in memory.
• Use only the specified rechargeable battery pack type as the main battery. Never use another type
of battery
