Replacing the Backup Battery
Important
• 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.
• Be sure to replace the backup battery as soon as possible whenever the following
message appears on the display: “Prevent possible data loss by promptly replacing
or recharging your back up battery according to your hardware manufacturer’s
instructions.”
