CONNECTING

HEADPHONES

To listen without disturbing others, you can connect a pair of 1/4-inch plug ste- reo headphones (not supplied) to the System 734. Your local Radio Shack store sells a wide selection of stereo headphones.

To connect headphones, plug the headphone’s 1/4-inch plug into the PHONES jack on the front of the Sys- tem 734.

Note: Connecting headphones auto- matically disconnects the System 734’s speakers.

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 begin listening, adjust the volume to a comfortable level.

•Do not listen at extremely high volume levels. Extended high-vol- ume listening can lead to perma- nent 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.
