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.

    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.

    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.

   

    3 remove the old lithium backup battery from the backup battery compartment with a ballpoint pen or other fine-tipped object as shown in the figure on the right. wipe the new lithium battery with a dry cloth and then insert it into the backup battery compartment with the plus (+) side facing up.

   

    4 close the cover and tighten the screws.
