AM/FM Stereo

OPERATION
With the Ignition Switch in "ACC" or "RUN", voltage is applied through Fuse 11 to operate Radio.

Fuse 8 applies voltage to the Radio at all times to power the memory related functions, which retain the memory portions with Radio turned off.

Panel dimming is controlled by the instrument panel dimming switch. A variable voltage is applied through the 19 (LB/R) wire to control the brightness of the panel lamps.

The display's brightness is controlled by the Main Light Switch. When the park lamps are turned on, battery voltage is applied to the Radio through the 484 (O/BK) wire, and the display dims. When the park lamps are turned off, voltage is no longer applied to the Radio, and the display brightens.
