CONNECTING AN EARPHONE

For private listening, plug an earphone into the earphone jack on the top
of your scanner.  This automatically disconnects the speaker.  We recommend
Radio Shack's earphone Cat. No. 33-175.  In a noisy environment, mono
headphones (Cat. No. 20-210) make listening easier.

Listening Safety

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 permanent hearing loss.

*  Set the volume to its lowest level before you begin listening.  After
   you put on the earphone, adjust the volume to a comfortable listening
   level.

*  Do not increase the volume once you establish a comfortable listening
   level.  Over time, your ears adapt to the volume level, so a volume
   level that does not cause discomfort might still damage your hearing.

Traffic Safety

Do not wear an earphone or headphones while operating a motor vehicle or
riding a bicycle.  This can create a traffic hazard and is illegal in some
areas.

Even though some earphones or headphones are designed to let you hear some
outside sounds when listening at normal volume levels, they still present
a traffic hazard.

CONNECTING AN EXTENSION SPEAKER

In a noisy area, an extension speaker such as Radio Shack Cat. No. 21-549,
positioned in the right place, might provide more comfortable listening.
Plug the speaker cable's 1/8-inch mini-plug into the scanner's earphone
jack.  You can also use a CAT. No. 21-541 amplified speaker in your
vehicle.
