PREPARATION
Your scanner’s display is protected
during shipment by a piece of blue
film. Peel off this film before you use
the scanner.
CONNECTING POWER
Note: If a power failure occurs or if
the DC cigarette-lighter power cable
or AC adapter is disconnected, the
scanner’s memory backup circuit
keeps information in memory for up
to 3 days.
Using Standard AC Power
You can power your scanner from a
standard AC outlet using the sup-
plied AC adapter.
Warning: Do not use the AC adapt-
er’s polarized plug with an extension
cord receptacle unless the blades
can be fully inserted to prevent blade
exposure.
Cautions:
• The supplied AC adapter sup-
plies 12 volts and delivers 500
milliamps. Its center tip is set to
positive, and its plug properly fits
the scanner’s
DC 12V jack.
Using an AC adapter that does
not meet these specifications
could damage the scanner or
the adapter.
• Be sure you connect the AC
adapter to the scanner before
you connect it to a standard AC
outlet. Then disconnect the
adapter from the AC outlet
before you disconnect it from the
scanner.
• If you have difficulty inserting the
AC adapter’s polarized plug, do
not force it. Turn it over and rein-
sert it.
1. Insert the supplied AC adapter’s
barrel plug into the scanner’s DC
12V jack.
2. Plug the adapter’s power mod-
ule into a standard AC outlet.
Using Vehicle Battery Power
To power your scanner from your ve-
hicle’s cigarette-lighter socket, you
need a DC cigarette-lighter power
cable such as Cat. No. 270-1533).
