PREPARATION

POWER SOURCES

You can power your scanner from any of three sources:

•Internal batteries or a rechargeable scanner battery pack (not supplied — see “Using Batteries”)

•Standard AC power (with an optional AC adapter — see “Using Standard AC Power” on Page 11)

•Vehicle battery power (with an optional DC adapter

—see “Using Vehicle Battery Power” on Page 12)

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” and “Charging a Rechargeable Battery Pack” on Page 13.

•If the scanner stops working properly after connect- ing it to power, try resetting it. See “Resetting/Initial- izing the Scanner” on Page 49.

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 from a rechargeable scanner battery pack, such as Cat. No. 23-288.

Note: You can also use six rechargeable nickel-cadmium batteries (such as Cat. No. 23-125) to power the scanner. To charge or recharge nickel-cadmium batteries, howev- er, you must remove them from the scanner and use an external charger (such as Cat. No. 23-134).
