Headphones and Speakers

You can plug headphones (not supplied) or an 
amplified speaker (not supplied) with a  
1/8-inch (3.5 mm) mini-plug earphone or in the 
headphone jack on top of your scanner. This 
automatically disconnects the internal speaker.

NOTE: Use an amplified speaker with this scanner; 
Non-amplified speakers do not provide sufficient 
volume for comfortable listening.

Listening Safely

To protect your hearing, follow these guidelines 
when you use headphones:

Set the volume to zero before putting on 
headphones. With the headphones on, adjust the 
volume to a comfortable level.

Avoid increasing the volume after you set it. Over 
time, your sensitivity to a volume level decreases, so 
volume levels that do not cause discomfort might 
damage your hearing.

Avoid or limit listening at high-volume levels. 
Prolonged exposure to high-volume levels can 
cause permanent hearing loss.

Wearing headphones while operating a motor 
vehicle or riding a bicycle can create a traffic hazard 
and is illegal in most areas. Even though some 
headphones let you hear some outside sounds 
when listening at normal volume levels, they still can 
present a traffic hazard. Exercise extreme caution!
