Radio with Cassette and 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, your
audio system adjusts automatically to make up for
road and wind noise as you drive. To get to SCV, press
the TUNE/AUDIO knob repeatedly until SPEED VOL
is displayed. Turn the TUNE/AUDIO knob to select OFF,
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. If you don’t want to use SCV,
select OFF.
DISP (Display): Press this button to switch the display
between the radio station frequency and the time.
The time can be displayed with the ignition on or off.
