At the start of each Listening Session, we recommend that you set a comfortable volume level and check to make sure the headphones are plugged all the way into the headphone jack. If they are not plugged in properly, you will only receive one channel, or mono sound, rather than two channels for stereo. Stereo sound is required.

If you hear sound coming through only one side, check your headphone connection.

If you are unable to adjust volume, make sure the headphones are plugged into the headphone jack. Some CD players have a "line out" jack that delivers a constant level of sound that is not adjustable.

If a CD will not play, first check to make sure it is placed in the CD player properly. If it still will not play, place another CD in the same player. If that CD will play, then your CD is either dirty or damaged. Try cleaning it with a CD cleaning kit. If it still will not play, then it is damaged, and you will need to contact your Provider to order a replacement.

If no CD will work in your CD player, the laser eye may be dirty. Use a CD player cleaning kit, and see if that resolves the problem. If not, take your CD player in for repair.
