Radio, Stereo, and Compact Disc: Description and Operation

The electronically tuned Radio receives an ignition signal from I/P Fuse Block Fuse 8D when the Ignition Switch is in "RUN," "ACCY" or during Retained Accessory Power. The clock and memory circuits receive power from I/P Fuse Block Fuse 9C at all times. When the Ignition Switch in "RUN," "ACCY" or during Retained Accessory Power, the vacuum fluorescent display illuminates to display the time or radio frequency setting. When the Radio "ON/OFF" switch is switched "ON," voltage is applied to the internal circuitry which provides a Radio "ON" signal to the power antenna.

The Radio illumination is controlled by the panel/interior lamp control dimmer. When the head/park lamp switch is in "PARK" or "HEAD," voltage is applied through the dimmer control to the Radio panel lamp and the internal circuitry. When the head/park lamp switch control dimmer switch is switched to "PARK" or "HEAD," voltage is applied through the I/P Fuse Block Fuse 4A to the Radio, signaling the internal circuitry to adjust the brightness of the vacuum fluorescent display to a level determined by the dimmer control.
