Connecting the Antenna

To attach the supplied telescopic antenna:
1. Insert the antenna in the hole on the top of the scanner.
2. Turn the antenna clockwise to tighten.

Connecting an Outdoor Antenna

To connect an external antenna, follow the installation instructions supplied
with the antenna. Use 50-ohm coaxial cable to connect your scanner to the
outdoor antenna. For lengths between 50 and 100 feet, use RG-8X low-loss
dielectric coaxial cable. For lengths over 100 feet, use RG8. You also may need
a BNC adapter (available at your local RadioShack store).

Warning: Use extreme caution when 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, touching 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.

Connecting Headphones

For private listening, you can plug Çinch (3.5 mm) mini-plug earphones or
headphones (not supplied), into the HEADPHONE jack on the back of the
scanner. This automatically disconnects the internal speaker.
Listening Safely
Do not wear headphones, earphones, or earbuds while operating a motor
vehicle or riding a bicycle. This can create a traffic hazard and could be illegal
in some areas.
To protect your hearing, follow these guidelines:
• Do not listen at high volume levels. Extended high-volume listening can
lead to permanent hearing loss.
• Set the volume to the lowest setting. Then turn on your audio device and
adjust the volume to a comfortable level.
• Avoid increasing the volume. Your ears will adapt to the volume level, so a
level that does not cause discomfort could still damage your hearing.

Connecting an Extension Speaker

In a noisy area, an amplified extension speaker (available from your local
RadioShack store or www.RadioShack.com), might provide more comfortable
listening. Plug the speaker cable's Ç inch (3.5 mm) miniplug into your scanner's
HEADPHONE jack.
n
Note: Use an amplified speaker with this scanner. Non-amplified speakers
do not provide sufficient volume for comfortable listening.
