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.
Warnin
g: Do not use the AC adapt-
er’s polarized plug...

9 Cautions:
• The DC cigarette-lighter power
cable must be capable of deliv-
ering 12 volts and 500 milli-
amps, its center tip must be set
to positive, and its barrel plug
must correctly fit the scanners
DC 12V jack. The recommended
power cable meets these speci-
fications. Using a power cable
that does not meet these specifi-
cations could damage the scan-
ner or the power cable.
• Always plug the power cable
into the scanner before you plug
it into your vehicles cigarette-
lighter socket. Always...

Connecting an Optional 
Antenna
The supplied telescoping antenna re-
ceives strong, local signals. Howev-
er, to receive weaker, more distant
signals in all bands, you can attach
an optional antenna, such as an ex-
ternal mobile antenna or outdoor
base station antenna. Your local Ra-
dioShack store sells a variety of an-
tennas.
Note: If you connect an external an-
tenna, remove the telescoping an-
tenna from the top of the scanner.
Always use 50-ohm coaxial cable,
such as RG-58 or RG-8, to connect
an...
