CONNECTING AN EARPHONE/ HEADPHONES

For private listening, you can plug an earphone or head- phones with a 1/8-inch mini-plug (such as Cat. No. 33-

175 or 20-210) into the jack on top of your scanner. This automatically disconnects the internal speaker.

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/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/headphones with your scanner, be very careful. Do not listen to a continuous broadcast. Even though some earphones/headphones let you hear some outside sounds when listening at normal volume levels, they still can present a traffic hazard.
