Speed Control Volume (SCV)
^ The AM/FM stereo with Integral Cassette Tape Player (UM) features Speed Control Volume (SCV).The volume level automatically adjusts to compensate for road and wind noise as you drive.
^ In order to use the SCV, adjust the volume to the listening level you want at any time.
^ As you drive, the volume will change in order to match the noise present at any particular speed. The volume should always sound the same level to you as you drive.
^ Each detent on the SCV allows a little more compensation at a faster rate.
