AM/FM Stereo

OPERATION
With the Ignition Switch in "ACC" or "RUN", voltage is applied through the RADIO Fuse and the 137 (Y/BK) wires to operate the Radio.

The MEMORY Fuse applies voltage to the Radio at all times through the 797 (LG/P) wires to power the memory-relayed functions, which retain the memory portions with the Radio and Ignition 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 panel lamps' brightness.

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.


The Radio Fuse applies voltage to the Antenna Switch through the 137 (Y/BK) wires when the Ignition Switch is in "ACC" or "RUN". Moving the Antenna Switch to "UP" applies power to the 745 (R/PK) terminal of the Power Antenna and ground to the 746 (DG/Y) terminal. With the Antenna Switch in the "DOWN" position, the 745 (R/PK) wire is grounded and the 746 (DG/Y) wire is powered. In either case, the motor runs in the appropriate direction.
