Playing the Radio PWR-VOL: Press this knob to turn the system on and off. To increase volume, turn the knob clockwise. Turn it counterclockwise to decrease volume. The knob is capable of rotating continuously. RECALL: Press this button to recall the station being played. If you press the button when the ignition is off, the clock will show for a few seconds. SCV: Your system has a feature called Speed-Compensated Volume (SCV). With SCV, your audio system adjusts automatically to make up for road and wind noise as you drive. Set the volume at the desired level. Turn the control ring behind the upper knob clockwise to adjust the SCV. Then, as you drive, SCV automatically increases the volume, as necessary, to overcome noise at any particular speed. The volume level should always sound the same to you as you drive. If you don't want to use SCV, turn the control all the way down. Each notch on the control ring allows for more volume compensation at faster vehicle speeds. AM-FM Stereo with Cassette Tape Player and Automatic Tone Control Your vehicle may be equipped with six BoseR amplified speakers. See your dealer for details. 3-13
