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. DlSP (Display): Press this button to switch the display between the radio station frequency and the time. Time display is available with the ignition turned off. 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 button repeatedly until SPEED VOL is displayed. Turn the TUNE/AUDIO button to select OFF, MIN, MED or MAX. Each higher choice 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.

By pressing and releasing the RCL button, you may retrieve four different categories of information: Artist, Song Title, Category or PTY, Channel Number/Channel Name. To change the default on the display, push this button until you see the display you want, then hold the knob until the display flashes. The selected display will now be the default. 3-66
