Connecting An Earphone/Headphones; Listening Safely - Radio Shack PRO-93 Owner's Manual

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 antenna's 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.
Warning: Use extreme caution when installing or re-
moving an outdoor antenna. If the antenna starts to fall,
let it go! It could contact overhead power lines. If the an-
tenna 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.
CONNECTING AN EARPHONE/
HEADPHONES
For private listening, you can plug an
mini-plug earphone or headphones (not supplied), avail-
able at your local RadioShack store, into the
top of your scanner. This automatically disconnects the
internal speaker.

Listening Safely

To protect your hearing, follow these guidelines when
you use an earphone or headphones.
• Do not listen at extremely high volume levels.
Extended high-volume listening can lead to perma-
nent hearing loss.
• Set the volume to the lowest setting before you
begin listening. After you begin listening, adjust the
volume to a comfortable level.
• Once you set the volume, do not increase it. Over
time, your ears adapt to the volume level, so a vol-
ume level that does not cause discomfort might still
damage your hearing.
