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 with four AA batteries. For the longest op-
eration and best performance, we recommend alkaline batteries (such
as Cat. No. 23-552). Or, you can use rechargeable nickel-cadmium bat-
teries (Cat. No. 23-125).
Warning:
The scanner has a built-in circuit that lets you recharge
nickel-cadmium batteries inside the battery compartment. However, you
must never use this circuit when you have installed non-rechargeable
batteries in the scanner. Be sure to read “Important Information about
the External Power Jacks” and “Charging Nickel-Cadmium Batteries.”
Follow these steps to install or replace batteries.
1. If the scanner is on, turn
VOLUME/OFF
counterclockwise until it
clicks to turn it off.
2. Press the tab on the battery compartment cover, and lift off the
cover.
3. Remove any old batteries from the compartment and cover.
Caution:
Always dispose of old non-rechargeable batteries
promptly and properly. Do not bury or burn them.
