SCV (Speed-Compensated Volume): With SCV, 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 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. RCL (Recall): Push this knob to display the station being played or to display the clock. Pushing this knob with the ignition off will display the clock. Finding a Station BAND: Press this button to switch between AM, FM1 and FM2. The display shows your selection. TUNE: Turn this knob to choose radio stations. SEEK : Press the up or down arrow to go to the next or previous station and stay there. The radio will seek to stations with a strong signal only. The sound will mute while seeking. SCAN : Press and hold one of the SCAN arrows for two seconds until SCAN appears on the display and you hear a beep. The radio will go to a station, play for a few seconds, then go on to the next station. Press one of the SCAN arrows again to stop scanning. The radio will scan to stations with a strong signal only. The sound will mute while scanning. To scan preset stations, press and hold one of the SCAN arrows for more than four seconds until PSCAN and the preset number appear on the display. You will hear a double beep. The radio will go to the first preset station stored on your pushbuttons, play for a few seconds, then go on to the next preset station.
