CONNECTING AN EARPHONE/
HEADPHONES
For private listening, you can plug an earphone or
mono headphones (such as Cat. No. 33-178 or 20-
210) into the jack on top of your scanner. This auto-
matically 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 per-
manent 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.
Traffic Safety
Do not use an earphone or headphones with your
scanner when operating a motor vehicle in or near traf-
fic. Doing so can create a traffic hazard and could be il-
legal in some areas.
If you use an earphone or headphones with your scan-
ner, be very careful. Do not listen to a continuous
broadcast. Even though some earphones/headphones
let you hear some outside sounds when listening at
normal volume levels, they still can present a traffic
hazard.
