Backup Batteries - Casio CASSIOPEIA IT-2000D User Manual

Backup batteries

The backup batteries protect the units memory contents whenever power from the main
battery pack is interrupted due to replacement of the battery pack, when the battery pack is
dead, etc.
Two lithium batteries are used for backup. The #2 backup battery is installed in the Data
Collector prior to shipment, but you must install the #1 backup battery that comes with the
Data Collector before using it for the first time.
Important! Dual backup batteries are employed in order to protect the #1 backup
battery from going dead. Note that memory contents cannot be
protected by the #2 backup battery alone.
To install the #1 backup battery
1
Loosen the screw that secures the backup
battery compartment cover in place. The
cover is designed so the screws cannot be
removed from the holes in order to protect
against particles falling out of the screw
threads into the battery compartment.
2
Lift up the side of the cover indicated in the
illustration, and then slide the cover in the
direction indicated by the arrow. Make sure
you do not damage the tab on end of the
cover.
3
Loosen the screw that holds the #1 backup
battery holder in place, and remove the
holder. The cover is designed so the screws
cannot be removed from the holes in order to
protect against particles falling out of the
screw threads into the battery compartment.
