Loading and Removing the Batteries
Two types of battery are used in the Handheld Terminal.
There are the main batteries used to operate the Handheld Terminal, and a backup
battery used for memory protection.
As the main batteries, use alkaline AA batteries or fully charged rechargeable AA
batteries (eneloop). To use rechargeable batteries, you must change the setting. (See
“Confi guring the Main Battery Settings” below.)
Use a lithium battery (CR2032) as the backup battery.
If an icon or message appears on the screen indicating that the batteries are exhausted,
replace them promptly.
Important!
The main batteries are used for both operation and backup, while the backup
battery provides power for memory backup only. Do not remove both batteries
at the same time. Removing both batteries, or removing the backup battery (or
main batteries) when the main (or backup) battery charge is low, could result in
data loss or corruption. Lost data cannot be recovered, so backup copies should
always be made of important data (such as by transferring data to a computer
using the optional cradle).
Always turn the Handheld Terminal off before replacing batteries.
Always use 2 new alkaline AA batteries or 2 fully charged rechargeable AA
batteries (eneloop) when replacing the main batteries. Using batteries other than
those specifi ed for this product, or using old and new batteries together, could
signifi cantly shorten the life of the batteries or cause malfunctions.
Always use a CR2032 battery when replacing the lithium battery.

You can choose either dry cell (alkaline) or rechargeable batteries as the main batteries.
