Using Vehicle Battery Power

To power your scanner from your ve-
hicle's battery power, you need a DC
power cord (such as Radio Shack
Cat. No. 270-1533).
Cautions:
• Your vehicle must have a 12-volt
DC, negative-ground electrical
system.
• The recommended DC power
cord supplies 12 volts and deliv-
ers at least 500 milliamps. The
center tip on the barrel plug is
set to positive, and the plug
properly fits the scanner's
jack. Using a DC power cord
12V
(or adapter) that does not meet
these specifications could dam-
age the scanner or the cord (or
adapter). The scanner's display
dims if the DC cord (or adapter)
you use does not provide the
required 12 volts DC.

Follow these steps to use vehicle
