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.
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 top of the scanner. This
automatically disconnects the internal speaker.
Listening Safely
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 com-
pany to remove the antenna.
DO NOT
attempt to do so yourself.
To protect your hearing, follow these guidelines when you use an earphone
or headphones.
• Set the volume to the lowest setting before you begin listening. After you
begin listening, adjust the volume to a comfortable level.
• Do not listen at extremely high volume levels. Extended high-volume lis-
tening can lead to permanent hearing loss.
• Once you set the volume, do not increase it. Over time, your ears adapt
to the volume level, so a volume level that does not cause discomfort
might still damage your hearing.
