CONNECTING AN EARPHONE/

HEADPHONES

For private listening, you can plug an earphone or mono headphones (such as Radio Shack 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 ear- phone or headphones:

•Do not listen at extremely high volume levels. Extended high-vol- ume listening can lead to permanent 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 volume level that does not cause discomfort might still damage your hearing.
