Using an Earphone
For private listening, plug a monaural
earphone (not supplied) with a

-inch
plug into the
EAR
jack on the right of
the radio. This automatically discon-
nects the built-in speaker.
Your local RadioShack store carries a
wide selection of earphones.
Listening Safely
To protect your hearing, follow these
guidelines when you use an ear-
phone.
• Set the volume to the lowest level
before you begin listening. After
you begin listening, adjust the vol-
ume to a comfortable listening lev-
el.
• Do not listen at extremely high vol-
ume 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 vol-
ume level that does not cause dis-
comfort might still damage your
hearing.
Traffic Safety
Do not wear an earphone while oper-
ating a motor vehicle or riding a bicy-
cle. This can cause a traffic hazard
and is illegal in some areas.
Even though some earphones let you
hear outside sounds when listening at
normal volume levels, they still can
present a traffic hazard.
