USING HEADPHONES

Listening Safely

To protect your hearing, follow these guidelines when you use headphones.

Set the volume to the lowest set- ting before you begin listening. After you put on the headphones, 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 level that does not cause discom- fort might still damage your hear- ing.

To listen to the system without disturb- ing others, plug a pair of stereo head- phones with a 1/8-inch plug (not supplied) into the system’s PHONES jack. This mutes the system’s speak- ers. Your local RadioShack store sells a wide selection of headphones.

Traffic Safety

Do not wear headphones 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 headphones are designed to let you hear some outside sounds when listening at normal vol- ume levels, they still present a traffic hazard.
