Controls in detail Control system CD changer operating mode General notes Should excessively high temperatures occur while in CD mode, CD TEMP HIGH will appear on the multifunction display and muting will take place. The unit will then switch back to the last operating mode used until the temperature has decreased to a safe operating level. Should excessively low temperatures occur while in CD mode, CD TEMP LOW will appear on the multifunction display, but the CD will continue to play. Handle CDs carefully to prevent interference during playback. Avoid fingerprints and dust on CDs. Do not write on CDs or apply any label or other material to them. Only use original CDs. Using copied CDs may create problems during playback. Clean CDs from time to time with a commercially available cleaning cloth. No solvents, anti-static sprays, etc. should be used for cleaning. Replace the CD in its case after use. Protect CDs from heat and direct sunlight. ! Your CD drive has been designed to play CDs which correspond to the IEC 60908 standard. If you insert thicker data carriers, e.g. ones that have data on both sides (one side with DVD data, the other side with audio data), they cannot be ejected and will damage the drive. For information on operating the CD changer, refer to separate COMAND operating instructions. Only use CDs which bear the label shown and that conform to the compact disc digital audio standard (IEC 60908). Use of CDs which do not meet this standard may cause damage to the CD changer. Do not play single-CDs (80 mm) with an adapter. 145
