CD player Random play sequence All of the tracks on the current CD are played at least once in a random sequence. Select "RND" and press the controller. General malfunctions The BMW CD player is optimized for operation in the vehicle. It may react more sensitively to defective CDs than devices intended for stationary use. If a CD cannot be played back, first check to make sure it has been correctly inserted. Humidity High humidity can fog the CD or the focusing lens for the laser beam, temporarily preventing playback. Malfunctions with individual CDs Cancel random playback: Select "RND" and press the controller. If malfunctions occur only with particular CDs, this can be due to one of the following causes. Home-recorded CDs Fast forward/reverse Press and hold the button for the corresponding direction. The tracks can be heard, but the sound is distorted. Malfunction sources in home-recorded CDs include, for example, inconsistent data origination and recording processes as well as low quality or pronounced aging of the blanks used. Only write on CDs with a marker especially designed for this purpose. Notes The BMW CD player is a Class 1 laser product. Never remove the cover from the housing. Do not operate with a damaged cover panel as this can lead to severe eye injury. Never play CDs or DVDs with stick-on labels. They can come loose during playback due to the heat buildup and cause irreparable damage to the system. Only use round CDs with a standard diameter of 4.7 in/12 cm and do not play CDs with an adapter, e.g. CD singles; otherwise, the CDs or the adapter can jam and may no longer eject properly.< Damaged CDs Avoid finger prints, dust, scratches, and moisture. Store CDs in a sleeve. Do not expose CDs to temperatures above 1227/50 6, high humidity or direct sunlight. CDs with copy protection Manufacturers often provide CDs with copy protection. This can prevent or limit the playback of these CDs.
