Setup
Power Sources
You can power your scanner from one of three sources:
• Rechargeable or non-rechargeable batteries (not
supplied).
• Standard AC power using an optional AC adapter
(not supplied).
• Vehicle power using an optional DC adapter (not
supplied).
Using Batteries
You can power the scanner with four AA batteries
(not supplied). For the longest operation and best
performance, we recommend alkaline batteries. If you
use rechargeable batteries, we recommend nickel-metal
hydride (Ni-MH) batteries.
Use the black battery holder for non-rechargeable
batteries. Use the yellow holder for rechargeable
batteries.
w
Warning: Never install non-rechargeable batteries
in the rechargeable yellow battery holder. Non-
rechargeable batteries can get hot or explode if you try
to recharge them.
To install batteries
1. Slide open the battery compartment cover on the
back of the scanner.
2. Place 4 AA batteries into the correct battery holder
matching polarity symbols (+ / –):
Black – Alkaline (non-rechargeable)
Yellow – Rechargeable Ni-MH or Ni-Cd
. Place the battery holder into the battery
compartment. The battery holder fits only one way.
Do not force it.
4. Replace the cover.

Battery Notes:
• When battery power is low, B appears and the
scanner beeps continuously. When battery power is
depleted, the scanner turns itself off.
• You must charge rechargeable batteries before you
use them the first time.
• Do not allow any metal objects such as key rings,
necklaces, etc. to touch the (+) and (–) terminals
when the battery holder contains batteries. Do not
carry or store the battery holder with metal objects.
• Use only fresh batteries of the required size and
recommended type. Do not mix old and new
batteries, different types (alkaline or rechargeable),
or rechargeable batteries of different capacities.
Doing so can damage the batteries, causing
chemicals or lead leaks, fire, or explosions.
