I Discs with rough or lipped edges.
I Discs with excessive thickness [Normal size is 1.2 mm (0.047 in).]
I Discs with scratches, abrasions, or pits on the surface.
I Discs with grease/oil, fingerprints, foreign material.
I Discs are warped due to excessive heat exposure.
3. Slide/place the discs in and out of the various magazine positions. Identify any discs and/or positions that require additional force for placement/ejection. If interference
(sticking, excessive tensions) is found, replace the magazine or the discs.
Note:
I Discs which are marginally out of specification (ex. dirty, scratched and so on) may play correctly
on a home stereo.
However, when used in the automative environment skipping may occur due to the added vehicle
movement and/or vibration due to road conditions. Autochangers should not be replaced when
discs are at fault.
I Use a soft damp cloth to wipe the discs starting from the center outward in radial direction. Never
use chemical cleaning solutions to clean the discs.
