CONNECTING THE SUPPLIED ANTENNA
You must install an antenna before you can operate the scanner.
The supplied telescoping antenna helps your scanner receive strong local sig-
nals. To install the antenna, thread it clockwise into the hole on top of the scan-
ner.
The scanner’s sensitivity depends on its location and the antenna’s length. For
the best reception of the transmissions you want to hear, adjust the antenna’s
length according to the chart below.
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 adapter.
Follow the installation instructions supplied with the antenna, route the antenna
cable to the scanner, then connect it to the antenna jack.
CONNECTING AN EARPHONE/HEADPHONES
For private listening, you can plug an 1/8 -inch (3.5-mm) mini-plug earphone or
headphones (not supplied), into the jack on the back of the scanner. This
automatically disconnects the internal speaker.

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.
