(Power/Volume): Press to turn the system on and off.

Turn clockwise or counterclockwise to increase or decrease the volume.

The radio goes to the previous volume setting when the radio is turned on. The volume can still be adjusted by using the volume knob.

Speed Compensated Volume (SCV): SCV automatically adjusts the radio volume to compensate for road and wind noise as the vehicle increases or decreases speed while driving. The volume level should sound about the same while driving. To activate SCV:

1. Set the radio volume to the desired level.

2. Press the MENU button to display the radio setup menu.

3. Press the pushbutton under the AUTO VOLUM (automatic volume) tab on the radio display.

4. Press the pushbutton under the desired Speed Compensated Volume setting (OFF, Low, Med, or High) to select the level of radio volume compensation. The display times out after approximately 10 seconds. Each higher setting allows for more radio volume compensation at faster vehicle speeds.
