Radio Operation

Delco(R) AM/FM Stereo With Clock:

RADIO DISPLAY ILLUMINATION
When the headlamps or parking lamps are turned on, the illumination of the display is controlled by the illumination controller (located on the lower instrument panel to the left of the steering wheel). When the headlamps or parking lamps are off, the display is lighted at 100% intensity and is not adjustable.

ON VOL
The ignition must be in the ACC or ON positions for the radio to operate. With the ignition in the OFF position, the time will be displayed for approximately five seconds by pressing the RCL button. When the ignition is in the ACC or ON positions and the radio is turned off, the time will be displayed and all controls except those required to set the clock will be deactivated; refer to Clock Operation. Turning the knob clockwise, past the detent, initially turns the radio on and turning further will increase volume. To decrease volume, turn the knob counterclockwise. Continuing past the detent turns the radio off.

RCL
Pressing the RCL button (with the radio on) will toggle the display between .the clock and radio frequency. After approximately 5 seconds, the display will revert to the clock. This dual function button is also used to set the clock; refer to Clock Operation.

AM-FM
Press this button to toggle between the AM and FM bands. AM or FM will appear on the display depending upon the band chosen, and the radio will automatically go to the frequency tuned when that band was last active.

SEEK
The seek function is activated by pressing either end of the button. Press to automatically tune to the next higher station within range. Press to automatically tune to the next lower station within range. In either case, when the end of the band is reached, the seek function will continue in the same direction at the opposite end of the band.

TUNE
Press and hold the button to manually tune to the next higher frequency. Press and hold the button to manually tune to the next lower frequency. If the button is held down in either direction for more than 1 second, it goes into fast tune. On the AM band, the frequency advances in increments of 10 kHz in both directions. On the FM band, the frequency advances in increments of 0.2 MHz in both directions. Release the button when desired frequency is reached. This dual function button is also used to set the clock; refer to Clock Operation.

Radio Frequency Preset Buttons
There are six station preset buttons numbered 1 through 6. They permit presetting of 12 stations (6 AM and 6 FM).
To set a station preset button:
1. Select the desired band (AM or FM).
2. Tune the radio to the desired station.
3. Press and hold the desired preset button for approximately 3 seconds. The sound will be interrupted during this step. When the sound resumes, the button is set to the desired station and the button can be released. The radio will now automatically tune to that pre-determined station when the button is pressed.

If the radio power is interrupted, the preset buttons lose their memory and must be reset.

Turn the BASS knob (outer ring) clockwise to increase bass and counterclockwise to decrease it. Turn the TREB knob (inner ring) clockwise to increase treble and counterclockwise to decrease it.

Adjusting Speaker Balance
Turn the BAL knob (outer ring) to move the sound between the right and left speakers. Turn the FADE knob (inner ring) to move the sound between the front and rear speakers.
