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."
