Stereo Headphone Jack

This unit includes a stereo PHONES jack on the front panel. You may connect a set of stereo headphones, not included, to this jack for private listening without disturbing others.

The built in speakers are automatically shut off when headphones are connected to the PHONES jack. Make sure that the plug from your headphones is fully inserted into the headphone jack. If the plug is not fully inserted the sound may be intermittent, or you may only hear sound from one side of the headphones.

Important: To prevent hearing damage always set the volume control to a low level before you connect the headphones. Then connect the headphones, put them on, and very gradually increase the volume to a comfortable listening level. Remember that CDs may contain both very soft and very loud passages. Adjust the volume to a comfortable level using a louder passage, so that you always know what the maximum level will be.
