Delco(R) AM/FM Stereo, Cassette Player And 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 PROG 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 tape eject and 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 PROG
Pressing the RCL PROG 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, FM1 or FM2 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.
If a cassette is playing, depressing the AM-FM button will stop the tape, retract the pinch rollers, and switch to receiver (radio) mode.
PRESET SCAN
Pressing the PRESET SCAN button will preview the preset stations on the band currently selected (AM, FM1 or FM2) starting with the first preset button and proceeding through the sixth button, stopping on each for approximately 5 seconds. Each frequency will be displayed as it is tuned. If not discontinued before reaching the sixth preset button, the radio will return to the first button and repeat the process. Press PRESET SCAN to cancel the preset scan function.

Radio Frequency Preset Buttons
There are six station preset buttons numbered 1 through 6. They permit presetting of 18 stations (6 AM and 12 FM-6 on FM1 and 6 on FM2).
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 the pre-determined station when the button is pressed.
If the radio power is interrupted, the preset buttons will lose their memory and must be reset. All six buttons have a dual function. Refer to Cassette Operation for details on their operation in the cassette mode.
Setting Tone
Turing the BASS knob (outer ring) clockwise will increase bass and turning counterclockwise will decrease it. Turning the TREB knob (inner ring) clockwise will increase treble and counterclockwise will decrease it.
NOTE: Both controls have a detent position at the center for balance of treble and bass. When a preset equalization is active, rotating either the TREB or BASS knobs will cancel the preset equalization and revert to BASS and TREB controls.
TONE SELECT
Press the TONE SELECT button to activate the preset tone feature and choose preset treble and bass equalization settings for ROCK, NEWS, POP, JAZZ or CLASSICAL. Each time the TONE SELECT button is pressed, a different setting will appear on the display. Press the TONE SELECT button again after CLASSICAL and control of tone will revert to the TREB and BASS controls.
NOTE: When a preset equalization is active, rotating either the TREB or BASS knobs will cancel the preset equalization and revert to BASS and TREB controls.
