The Basics
listening safely
To protect your hearing, follow these guidelines when you
use an earphone or 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 once 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.
traffi c safety
Do not wear an earphone or headphones while you drive a
vehicle or ride a bicycle. This can create a traffi c hazard and
can be illegal in some areas. Even though some earphones
and headphones let you hear some outside sounds when you
listen at normal levels, they still can present a traffi c hazard.
connecting an extension speaker
In a noisy area, an amplifi ed speaker (not supplied), available
at your local RadioShack store, might provide more
comfortable listening. Plug the speaker cable’s 1/8-inch (3.5
mm) mini-plug into your scanner’s jack.
