PREPARATION

POWER SOURCES

You can power your scanner from any of three sources:

•Internal batteries (not supplied)

•Standard AC power (using an optional AC adapter)

•Vehicle battery power (using an optional DC adapter)

Using Internal Batteries

You can power your scanner using four AA batteries. For the longest operation and best performance, we recommend alkaline batteries (such as Cat. No. 23- 552).

You can also use four rechargeable nickel-cadmium batteries (Cat. No. 23-125). Before you use nickel-cad- mium batteries, you must charge them (see “Charging Nickel-Cadmium Batteries” on Page 11).

Follow these steps to install batteries.

1.Turn VOLUME/OFF counterclockwise until it clicks to make sure the power is turned off.

2.Slide up and hold the tab on the back of the scan- ner, then pull up the battery compartment cover.
