Battery Replacement - Casio Cassiopeia E-125 Service Manual And Parts List

5-2. Battery Replacement

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 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
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."
• 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 Application 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 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.
