-inch (3.5-mm) plug into the
jack. Your local RadioShack store has
a wide selection of headphones.
Listening Safely
To protect your hearing, follow these
guidelines when you use headphones.
Set the volume to its lowest set-
ting 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-vol-
ume listening can lead to perma-
nent 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.
