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.
