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.
