USING EARPHONES
For private listening, you can con-
nect a pair of earphones (not sup-
plied) with a
1
/8-inch plug. Your local
Radio Shack store carries a wide se-
lection of earphones.
Insert the earphones’
1
/8-inch plug
into the PHONES jack on the side of
the SCR-99.
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.
TRAFFIC SAFETY
Do not wear earphones while operat-
ing a motor vehicle or riding a bicy-
cle. This can create a traffic hazard
and is illegal in some areas.
Even though some earphones are
designed to let you hear some out-
side sounds when listening at normal
volume levels, they still present a
traffic hazard.
