Playing the Radio
PWR (Power): Push this knob to turn the system
on and off.
VOL (Volume): Turn this knob clockwise or
counterclockwise 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.
Set the volume at the desired level. Press this
button to select MIN (minimum), MED (medium),
or MAX (maximum). 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 button until OFF displays.
RCL (Recall): Push this knob to switch the
display between the radio station frequency and
the time. When the ignition is off, push this knob
to display the time.
