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 wear an earphone or headphones while you drive a vehicle or ride a bicycle. This can create a traffic 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 lev- els, they still can present a traffic hazard.

CONNECTING AN EXTENSION SPEAKER

In a noisy area, an amplified 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 .
