PREPARATION
POWER SOURCES
You can power your scanner from any of four sources:
h Internal batteries (not supplied) with the provided battery
holder
h A rechargeable scanner battery pack (not supplied)
h Standard AC power (using an optional AC adapter)
h Vehicle battery power (using an optional DC cigarette-
lighter adapter)
You can power your scanner from six AA batteries. For the
longest operation and best performance, we recommend
alkaline batteries. You can also power the scanner using a
rechargeable scanner battery pack or rechargeable nickel-
cadmium batteries, and recharge it as you use the scanner.
Caution: Do not mix old and new batteries, different types of
batteries (standard, alkaline, or rechargeable), or recharge-
able batteries of different capacities.
Notes:
h The PWR jack lets you connect an external AC or DC
adapter to operate the scanner. Connecting an adapter
to PWR disconnects the internal batteries. You can use
the PWR jack with either non-rechargeable or recharge-
able nickel-cadmium batteries installed.
h The CHG jack lets you connect an external AC or DC
adapter to operate the scanner. The internal batteries re-
main connected when you connect an adapter to CHG ,
and get recharged when you connect a charger.
Warning: Never use the CHG jack with non-rechargeable
batteries! If you try to recharge non-rechargeable batteries,
they could get very hot and explode.
Battery Install
1. Press down on the battery compartment cover on the bot-
tom of the scanner and slide the cover in the direction to
remove it.
