In rare cases, a radio station can broadcast incorrect information that causes the radio features to work improperly. If this happens, contact the radio station. 4. Press the pushbutton under the desired Speed Compensated Volume setting (OFF, Low, Med, or High) to select the level of radio volume compensation.
