Radio, Stereo, and Compact Disc: Description and Operation

The Radio receives battery voltage at all times on CKT 640 through I/P Fuse 30 to keep clock and preset station memory alive when the Ignition is "OFF." With the Ignition Switch in "ACCY" or "RUN," voltage is applied to CKT 43 through I/P Fuse 9 to enable Radio operation.

When the Park Lamps or Headlamps are turned "ON," voltage is applied to the Radio on CKT 32 from the Headlamp Switch. When voltage is applied to CKT 32 at the Radio, the Radio will dim the display a preset amount. With the Headlamps or Park Lamps "ON," the Radio display may be dimmed manually using the I/P Dimmer Switch. The I/P Dimmer Switch varies the voltage on CKT 8 to the Radio to control display dimming.
