DESCRIPTION AND OPERATION
Compact Disc Player
The following is a description of the various controls.
NOTE: Three inch compact disc singles are not recommended for use with the Ford
Compact Disc Player.
Once a disc is inserted, the operation of the disc will override that of
the cassette player or radio. The volume, tone and fader controls on the radio
are used to control the sound of the compact disc player.
NOTE: The CD player has heat protection circuitry to protect the laser diode.
If the temperature of the player reaches 80°C
(176°F), the heat detection circuit will shut off the player
and "H" will appear in the display. When the temperature is within normal
operating range the "H" indicator will turn off and the CD player will again be
operational.
