Radio with Six-Disc CD RCL (Recall): Press this knob to switch the display between the radio station frequency and the time. When the ignition is off, press this knob to display the time. To change the default on the display, press the RCL knob until you see the display you want, then hold the knob until the display flashes. The selected display will now be the default. AUTO VOL (Automatic Volume): The system has a feature called automatic volume. With this feature, the audio system adjusts automatically to make up for road and wind noise as you drive. The radio has a blinking red light that is used as a theft-deterrent feature. The light will blink whenever the ignition is off. Playing the Radio PWR (Power): Push this knob to turn the system on and off. VOLUME: Turn this knob to increase or to decrease the volume. Set the volume at the desired level. Press this button to select MIN, MED, or MAX. Each higher setting will allow for more volume compensation at faster vehicle speeds. Then, as you drive, automatic volume increases the volume, as necessary, to overcome noise at any speed. The volume level should always sound the same to you as you drive. To turn automatic volume off, press this button until OFF appears on the display. 3-53
