4-2. Battery Replacement
You 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 dialog to keep informed about the current levels of
your main and backup batteries. See the separate Palm-size PC User’s Guide for more information
about this dialog.
• Icons appear in the Taskbar to let you know when battery power is low. See the separate Plam-size 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.
“Prevent possible data loss by promptly replacing or recharging your main batteries according
to your hardware manufacturer’s instructions.”
Backup Battery
Replace the backup battery as soon as possible after the following message appears.
“Prevent possible data loss by promptly replacing or recharging your backup battery according
to your hardware manufacturer’s instructions.”
• 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 the separate Palm-size PC User’s Guide for
information about backing up data.
• See the separate Plam-size PC User’s Guide for information about using the Card Backup Tool pro-
gram 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.
If unit power turns off due to insufficient power, the following warning message appears on the display
the next time you turn on unit power.
“Warning
Due to high current demand by hardware, the system powered down in order to protect memory
contents...”
If unit power turns off due to sudden power drain by a CompactFlash card, the following warning mes-
sage appears on the display the next time you turn on unit power.
“Warning
Due to high current demand by the card, the system powered down in order to protect memory
contents...”
Important
Be sure to observe the following important battery handling precautions. Failure to do so can cause
batteries to leak, resulting in damage to surrounding items and create the danger of fire and electrical
shock.
