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: "Backup Battery Very Low To prevent possible data loss, replace or
recharge your backup battery according to the owner's manual."
1. Make sure your CASSIOPEIA is turned off.
• Press the [Power] button to turn off power.
2. Turn the CASSIOPEIA over.
3. Slide the battery cover switch to BACK UP, and then remove the backup battery cover.
4. Remove the old battery.
5. Wipe off a new lithium battery (CR2032) with a dry cloth, and load it into the CASSIOPEIA.
Make sure the positive side is facing up, so you can see it.
6. Replace the backup battery cover.
7. Slide the battery cover switch back to LOCK.
