Common Operating Conditions of Your CD Changer
The following information is designed to help you recognize typical
situations that could be mistakenly interpreted as mechanical
malfunctions of the disc player.
A disc is already loaded.
The disc is inserted with the label surface downward.
The disc is dusty or defective.
The player's internal temperature is above 167° F (75° C).
Allow the player to cool off before operating.
Different manufacturers of compact discs may produce discs
with different dimensions or tolerances, some of which may
not be within industry standards or in accordance with the CD
format. Because of this, a new disc that is free of dust and
scratches could be defective and may not play on your Ford
Compact Disc Changer.
If play does not begin after the CD button is pushed:
Moisture may have condensed on the lenses within the unit. If
this occurs, remove the disc and wait approximately an hour
until the moisture evaporates.
If the sound skips:
Badly scratched discs or extremely rough roads will cause the
sound to skip. Skipping will not damage the disc player or
scratch the discs.
