CONNECTING AN

EARPHONE/

HEADPHONES

For private listening, you can connect an earphone or headphones with a 1/8- inch (3.5-mm) plug to the jack on the front of the scanner. (Your local RadioShack store carries a wide se- lection of earphones and head- phones). This automatically dis- connects 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 per- manent hearing loss.

•Set VOLUME to the lowest setting before you begin listening. After you begin listening, adjust VOL- UME to a comfortable level.

•Once you set VOLUME, do not increase it. Over time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing.
