USING EARPHONES

RadioShack store carries a wide se-
lection of earphones.

Note: Connecting earphones auto-
matically disconnects the built-in
speaker.
Listening Safely
To protect your hearing, follow these
guidelines when you use earphones.
• Set the volume to the 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-
volume listening can lead to per-
manent 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.
