Controls in detail Audio system CD changer operation General notes Should excessively high temperatures occur while in CD mode, CD TEMP HIGH will appear in the display and the CD will be muted. The unit will then switch back to the last operating mode used until the temperature has decreased to a safe operating level. Only use original CDs. Using copied CDs may create problems during playback. Clean CDs from time to time with a commercially available cleaning cloth. Do not use solvents, anti-static sprays, etc. for cleaning. Replace the CD in its case after use. Protect CDs from heat and direct sunlight. i 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. 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. Warning! G Should excessively low temperatures occur while in CD mode, CD TEMP LOW will appear in the 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 labels or other material to them. Only use CDs, which bear the label shown and that conform to the compact disc digital audio standard (IEC 60908). You can therefore only use CDs with a maximum thickness of 1.3 mm. The CD changer is a Class 1 laser product. There is a danger of invisible laser radiation if the cover is opened or damaged. Do not remove the cover. The CD changer does not contain any parts which can be serviced by the user. For safety reasons, have any service work which may be necessary performed only by qualified personnel. 158
