Playing the Radio
PWR (Power): Press this knob to turn the system
on and off.
VOL (Volume): Turn the knob to increase or to
decrease volume.
AUTO VOL (Automatic Volume): With automatic
volume, your 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 LOW, MEDIUM or HIGH. AVOL will appear on
the display. 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. NONE will appear on the display if the radio
cannot determine the vehicle speed. If you don't want
to use automatic volume, select OFF.
DlSP (Display): Push this knob to switch the display
between radio station frequency and time. Time display
is available with the ignition turned off.
To change the default on the display, push the knob
until you see the display you want, then hold the knob
for two seconds. The radio will produce one beep
and selected display will now be the default.
