Notes on pick-up errors

In stationary vehicle:

• Check the CDs for impurities or scratches
  
• If the CDs are in perfect order and function satisfactorily in other devices, the changer should be sent back to the factory for inspection. If applicable, also enclose the CDs which cannot be played with a short description of when the fault occurs. For example: "No playback as of track 5, 1:34 minutes".
  

While driving:

• Dirty CDs can increase the sensitivity to vibration and impact. Please check accordingly.
  
• Have the transport screws been removed?
  
• Are the mounting springs in the correct position?
  
• Are the springs in the same position on both sides?
  
• There are, of course, also limits in the case of extremely hard chassis or high speeds. As soon as the mechanical part comes in contact with the housing as the result of vibration and impact, the electronic error correction can no longer function effectively or the pick-up tracking is no longer operable due to the lack of correction data.
