PREPARATION

POWER SOURCES

You can power your scanner from any of four sources:

Internal batteries (not supplied) with the provided battery holder

A rechargeable scanner battery pack (not supplied)

Standard AC power (using an optional AC adapter)

Vehicle battery power (using an optional DC cigarette- lighter adapter)

Notes:

Connecting an AC or DC adapter to the scanner dis- connects any internal batteries, but it does not dis- connect a rechargeable battery pack. If you install a rechargeable battery pack, you can operate the scanner and recharge the battery pack at the same time. See “Using Batteries” below and “Charging a Rechargeable Battery Pack” on Page 14.

If the scanner stops working properly after you con- nect it to power, try resetting it. See “Resetting/Initial- izing the Scanner” on Page 50.

Using Batteries

You can power your scanner from six AA batteries. For the longest operation and best performance, we recommend alkaline batteries, such as RadioShack Cat. No. 23-552. You can also power the scanner using a rechargeable scanner battery pack, such as Cat. No. 23-288, and re- charge it as you use the scanner.
