USING AN EARPHONE

For private listening, you can con-
nect a monaural earphone (not sup-
plied) with a

/8-inch plug to the

CTR-98. Your local Radio Shack
store carries a wide selection of ear-
phones.

Insert the earphone’s

/8-inch plug

into the EAR jack on top of the CTR-
98.

Note: Connecting an earphone auto-
matically disconnects the built-in
speaker.

LISTENING SAFELY

To protect your hearing, follow these
guidelines when you use an ear-
phone.

• 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 an earphone while oper-
ating 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.
