CONNECTING AN
EARPHONE/
HEADPHONES
For private listening, you can connect an earphone or headphones with a 1/8- inch plug (such as Cat. No. 
jack on the front of the scanner. 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.
