CONNECTING AN EARPHONE/
HEADPHONES
For private listening, you can plug an earphone or mono headphones
(not supplied) with a
1 / 8 -inch (3.5-mm) plug (such as Cat. No. 33-177 or
20-210) into the jack on top of your scanner. This automatically dis-
connects the internal speaker.
Listening Safely
To protect your hearing, follow these guidelines when you use an ear-
phone or headphones.
• Set the volume to the lowest setting before you begin listening.
After you begin listening, adjust the volume to a comfortable level.
• Do not listen at extremely high volume levels. Extended high-
volume listening can lead to permanent hearing loss.
• Once you set the volume, do not increase it. Over time, your ears
adapt to the volume level, so a volume level that does not cause
discomfort might still damage your hearing.
Traffic Safety
Do not use an earphone or headphones with your scanner when oper-
ating a motor vehicle or riding a bicycle in or near traffic. Doing so can
create a traffic hazard and could be illegal in some areas.
If you use an earphone or headphones with your scanner while riding a
bicycle, be very careful. Do not listen to a continuous broadcast. Even
though some earphones or headphones let you hear some outside
sounds when listening at normal volume levels, they still can present a
traffic hazard.
