� You can use two AA alkaline batteries or the optional NiMH Rechargeable Battery Pack to power your unit, or the AC adaptor included in the optional Docking Station Kit.

� If the main batteries are not installed, or are depleted, the unit will
not function even when connected to an AC power source.

� Caution: When the main batteries are depleted, replace them
promptly with new batteries. If the depleted main batteries are not replaced, the backup battery will be drained more quickly than normal, and data loss may occur after about 2 weeks.

Important points to remember when installing new batteries:

� Be sure not to use any of the following as main batteries: manganese batteries or nickel cadmium rechargeable batteries. These are easily mistaken for alkaline batteries.

4. Insert the other end of the cable into the serial port on your PC that you specified during the Windows CE Services installation.

� Do not remove the main batteries and the backup battery at the
same time (this will result in the loss of all stored data).

� Backup important data before replacing batteries. � Replace both main batteries at the same time with new batteries of
the same type.

� When the main battery low warning message and the backup
battery low warning message appear at the same time, replace the backup battery first. After the backup battery replacement, turn on your unit and make sure the backup battery low message is gone, then you can proceed to replace the main batteries.
