Connecting An Earphone/Headphone; Listening Safely - Radio Shack PRO-83 User Manual

Note: Always use 50-ohm, RG-58, or RG-8, coaxial
cable to connect an outdoor antenna. If the antenna
is over 50 feet from the scanner, use RG-8 low-loss
dielectric coaxial cable. If your antenna's cable does
not have a BNC connector, your local RadioShack
store carries a variety of BNC adapters.

Connecting an Earphone/Headphone

For private listening, you can plug a
(3.5 mm) mini-plug earphone or mono headphones
(not supplied) into the headphone jack on 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
permanent hearing loss.
• Set the volume to the lowest setting before you
begin listening. After you begin listening, adjust
the volume to a comfortable level.
