  • Place the adaptor in the cassette slot next.
  • Locate the “tape” mode on the audio system’s menu and push play.
  • The music will begin to play, and the volume can be adjusted to your desire.This method is effective if a cigarette lighter cannot be used, the power port is malfunctioning, or the FM transmitter has a weak signal.
