USING VEHICLE BATTERY POWER
You can power the scanner from a vehicle’s 12V power source (such as ciga-
rette-lighter socket) using a 9VDC at least 400-mA adaptor with 4.75mm outer/
1.7mm inner plug. Its center tip must be set to positive and its plug must fit the
scanner’s PWR DC 9V jack. Using an adaptor that does not meet these speci-
fications could damage the scanner or the adaptor.
Cautions:
Always connect the DC adaptor to the scanner before you connect
it to the power source. When you finish, disconnect the adaptor from the power
source before you disconnect it from the scanner.
To power the scanner using a DC adaptor, connect the plug into the scanner’s
PWR DC 9V jack. Plug the other end of the DC adaptor into your vehicle’s
cigarette-lighter socket.
Note:
If you use a cigarette-lighter power cable and your vehicle’s engine is
running, you might hear electrical noise from the engine while scanning. This is
normal.
CONNECTING THE SUPPLIED ANTENNA
To attach the supplied flexible antenna to the antenna jack on top of your scan-
ner, align the slots around the antenna’s connector with the tabs on the an-
tenna jack. Press the antenna down over the jack and turn the antenna’s base
clockwise until it locks into place.
Connecting an Outdoor Antenna
The antenna connector on your scanner makes it easy to use the scanner with
a variety of antennas, such as an external mobile antenna or outdoor base
station antenna.
Always use 50 Ohm coaxial cable, such as RG-58 or RG-8, to connect an out-
door antenna. For lengths over 50 feet, use RG-8 low-loss dielectric coaxial
cable. If the antenna cable’s connector does not have a BNC connector, you
will also need a BNC adaptor.
Follow the installation instructions supplied with the antenna, route the antenna
cable to the scanner, then connect it to the antenna jack.
Warning:
Use extreme caution when you installing or removing an outdoor
antenna. If the antenna starts to fall, let it go! It could contact overhead
power lines. If the antenna touches a power line, contact with the antenna,
mast, cable, or guy wires can cause electrocution and death. Call the power
company to remove the antenna.
DO NOT
attempt to do so yourself.
