Replacing the Lithium Backup Battery
When the lithium backup 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 Data Collector OFF before you do this.
[Warning]

Note Down Valuable 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 the optional Basic
Cradle or Satellite Cradle 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.
