5 The Basics
powering your scanner
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)
Before installing batteries, set the switch in the
battery compartment to match the type of batteries
you will use. Select RECHARGEABLE for all
non-alkaline battery types, including lithium, Ni-Cd
and Ni-MH.
Remove battery cover and set battery switch.
