E-17Loading and Removing the BatteriesTwo types of battery are used in the Handheld Terminal.There are the main batteries used to operate the Handheld Terminal, and a backupbattery used for memory protection.As the main batteries, use alkaline AA batteries or fully charged rechargeable AAbatteries (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 backupbattery provides power for memory backup only. Do not remove both batteriesat the same time. Removing both batteries, or removing the backup battery (ormain batteries) when the main (or backup) battery charge is low, could result indata loss or corruption. Lost data cannot be recovered, so backup copies shouldalways be made of important data (such as by transferring data to a computerusing the optional cradle).Always turn the Handheld Terminal off before replacing batteries.Always use 2 new alkaline AA batteries or 2 fully charged rechargeable AAbatteries (eneloop) when replacing the main batteries. Using batteries other thanthose specified for this product, or using old and new batteries together, couldsignifi cantly shorten the life of the batteries or cause malfunctions.Always use a CR2032 battery when replacing the lithium battery.Configuring the Main Battery SettingsYou can choose either dry cell (alkaline) or rechargeable batteries as the main batteries.At shipment from the factory, the “DRY CELL” setting is selected.To use rechargeable (eneloop) batteries, you must change the setting.
