USING AN EARPHONE

For private listening, you can con- nect a monaural earphone (not sup- plied) with a 1/8-inch plug to the CTR-98. Your local Radio Shack store carries a wide selection of ear- phones.

Insert the earphone’s 1/8-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.
