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.
Traffic Safety
Do not use an earphone or headphones with your scan-
ner when operating a motor vehicle in or near traffic. Do-
ing so can create a traffic hazard and could be illegal in
some areas.
If you use an earphone or headphones with your scan-
ner, be very careful. Do not listen to a continuous broad-
cast. Even though some earphones/headphones let you
hear some outside sounds when listening at normal vol-
ume levels, they still can present a traffic hazard.
