Safety precautions

Make sure to ground the unit to a negative 12V DC power supply. Do not install the unit in a spot exposed to direct sunlight or excessive heat or humidity. Also avoid places with too much dust or the possibility of water splashing. Do not place the faceplate (and the faceplate case) in areas exposed to direct sunlight, excessive heat or humidity. Also avoid places with too much dust or the possibility of water splashing. To prevent deterioration, do not touch the terminals of the unit or faceplate with your fingers. Do not subject the faceplate to excessive shock, as it is a piece of precision equipment. When replacing a fuse, only use a new fuse with the prescribed rating. Using a fuse with the wrong rating may cause your unit to malfunction. Do not apply excessive force to the open faceplate or place objects on it. Doing so will cause damage or breakdown.
You can damage both your unit and the CD changer if you connect them incorrectly.
