Replacing the Backup Lithium Battery
When the backup lithium battery low voltage message appears on the LCD screen,
immediately replace the backup battery (lithium). Use a CR2032 lithium battery as the
replacement battery. Be sure to turn the Handheld Terminal OFF before you do this.
[Caution]
■ For Important Data
• When you remove the backup battery with the main battery removed or
in a low-power state, data may be lost or may change. Data cannot be
recovered once it is lost or corrupted. Be sure to make back-up copies
of all important data. One way to do this is to use one of the optional
cradles to transfer data to a computer.
Important! • Make sure that the positive (+) and negative (–) ends of the battery are
facing the correct directions.
1 Use a screwdriver to rotate the screw that
secures the backup battery holder in place
counterclockwise to loosen it.
2 Open the backup battery compartment cover.
