PREPARATION

POWER SOURCES

You can power your scanner from any of three sources:

•internal batteries

•standard AC power (using an optional AC adapter)

•vehicle battery power (using an optional DC adapter)

INSTALLING BATTERIES

Your scanner requires 4 AA batteries (not supplied) for power. For the best performance and longest life, we recommend alkaline batteries. Or, you can use rechargeable nickel-cadmium batteries. Both types of batteries are available at your local RadioShack store.

Warning: The scanner has a built-in circuit that lets you recharge nickel-cadmium batteries inside the battery compartment. How- ever, you must never use this circuit when you have installed non- rechargeable batteries in the scanner. Be sure to read “Important Infor- mation About the External Power Jacks” on Page 9 and “Charging Nickel-Cadmium Batteries” on Page 12.

Cautions:

•Use only fresh batteries of the required size and recommended type.

•Do not mix old and new batteries, different types of batteries (stan- dard, alkaline, or rechargeable), or rechargeable batteries of differ- ent capacities.

1.Press down the tab on the battery compartment cover, and lift open the compartment.
