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.
