Radio with CD
Playing the Radio
PWR (Power): Push this knob to turn the system on
and off.
VOL (Volume): Turn this knob to increase or to
decrease the volume.
SCV (Speed-Compensated Volume): With SCV,
the audio system adjusts automatically to make up for
road and wind noise as you drive.
To get to SCV, push the TUNE/AUDIO knob repeatedly
until SPEED VOL appears on the display. Turn the
TUNE/AUDIO knob to select MIN, MED, or MAX.
Each higher setting allows for more volume
compensation at faster vehicle speeds. Then, as you
drive, SCV automatically 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 SCV off, press this knob until OFF
appears on the display.
DISP (Display): Press this button to switch the display
between the radio station frequency and the time.
Press this button to display the time with the ignition
turned off.
