Preparation
Cautions:
You must use a power source that sup-
plies 9V DC and delivers at least 300 mA.
Its center tip must be set to positive and
its plug must fit the scanners 
PWR DC 9V jack.
Using an adapter that does not meet these specifi-
cations could damage the scanner or the adapter.
• Always connect the DC adapter to the scanner
before you connect it to the power source. When
you finish, disconnect the adapter from the power
source before you disconnect it from the scanner.

15Preparation
Always use 50-ohm coaxial cable, such as RG-58 or
RG-8, to connect an outdoor antenna. For lengths over
50 feet, use RG-8 low-loss dielectric coaxial cable. If
your antennas cable does not have a BNC connector,
you will also need a BNC adapter (not supplied, avail-
able at your local RadioShack store).
Follow the installation instructions supplied with the an-
tenna, route the antenna cable to the scanner, then con-
nect it to the antenna jack.

Traffic Safety
Do not wear an earphone or headphones while you drive
a vehicle or ride a bicycle. This can create a traffic haz-

present a traffic hazard.
Connecting an Extension Speaker
In a noisy area, an amplified speaker (not supplied),
available at your local RadioShack store, might provide
more comfortable listening. Plug...
