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 scanner when operating 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/ headphones let you hear some outside sounds when lis- tening at normal volume levels, they still can present a traffic hazard.
