PREPARATION

INSTALLING BATTERIES

You can power your scanner with four AA batteries (not sup-
plied). For the best performance and longest life, we recom-
mend RadioShack alkaline batteries.
You can use either the black non-rechargeable battery holder
or the yellow rechargeable battery holder (both supplied) to
hold the batteries. If you use the yellow battery holder, we rec-
ommend nickel-cadmium or nickel-metal hydride batteries (not
supplied).
Cautions:
• Use only fresh batteries of the required size and recom-
mended type.
• Do not mix old and new batteries, different types of batter-
ies (standard, alkaline, or rechargeable), or rechargeable
batteries of different capacities.
Warning: Never install non-rechargeable batteries in the yel-
low rechargeable battery holder. Non-rechargeable batteries
can get hot or explode if you try to recharge them.
Follow these steps to install batteries.
1. Press down on the battery compartment cover then slide
the cover in the direction of the arrow to remove it.
2. If you are using non-rechargeable batteries, place them
into the black holder, as indicated by the polarity symbols
(+ and –) marked on the holder. Or, if you are using
rechargeable batteries, place them into the yellow holder
as indicated by the polarity symbols (+ and –) marked on
the holder.
3. Place the battery holder into the battery compartment.
Caution: The battery holder fits only one way inside the
battery compartment. Do not force it.
4. Replace the cover.
When B flashes on the display and the scanner beeps, or if
the scanner stops operating properly, replace the batteries.
