CONNECTING AN EARPHONE/
HEADPHONES
For private listening, you can plug an earphone or mono headphones (not supplied) with a 
jack on top of your scanner. This automatically dis- connects the internal speaker.
Listening Safely
To protect your hearing, follow these guidelines when you use an ear- phone or headphones.
•Set the volume to the lowest setting before you begin listening. After you begin listening, adjust the volume to a comfortable level.
•Do not listen at extremely high volume levels. Extended high- volume listening can lead to permanent hearing loss.
•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.
Traffic Safety
Do not use an earphone or headphones with your scanner when oper- ating 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 or headphones with your scanner while riding a bicycle, be very careful. Do not listen to a continuous broadcast. Even though some earphones or headphones let you hear some outside sounds when listening at normal volume levels, they still can present a traffic hazard.
