To assure your safety, please request a specialist technician to install the unit. • When you make a hole to install the camera, check the location of pipes, tanks and wiring and avoid touching them. Otherwise it may cause the fire. • When you make a hole with a drill, use goggles to protect your eyes. CAUTION To prevent damage to the product, take the following precautions: • Make sure to ground the unit to a negative 12V/24V DC power supply. • 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 use your own screws. Use only the screws provided. If you use the wrong screws, you could damage the unit. NOTE • This product is a camera that provides mirror images (left and right inverted). • The TV can be connected to an RCA video input that is compatible with the HD camera picture quality, but please check whether the TV you use has a reverse gear activation function. • This product is designed to supplement the driver's rear view, but the camera images do not show all dangers and obstacles. Be sure to look behind you when reversing to confirm the view. • This product features a wide-angle lens, so the near view is wide and the far view is narrow, which may create a false sense of distance. Be sure to look behind you when reversing to confirm the view. • Do not wash your car with an automatic car wash or high-pressure water as it may result in water entering the camera or the camera falling off. • Check camera bracket installation before driving. Are the screws loose? - Is the camera bracket firmly secured? - If the rear view camera comes loose while you are driving it may cause an accident. • Before finally installing the unit, connect the wiring temporarily, making sure it is all connected up properly, and the unit and the system work. • When mounting this unit, make sure none of the leads are trapped between this unit and the surrounding metalwork or fittings. • Do not mount this unit near the heater outlet, where it would be affected by heat, or near the doors, where rainwater might splash onto it. (Never install in locations such as the above because of the danger of malfunction due to high temperatures.) • Before drilling any mounting holes always check behind where you want to drill the holes. Do not drill into the gas line, brake line, electrical wiring or other important parts. • If this unit is installed in the passenger compartment, anchor it securely so it does not break free while the car is moving, and cause injury or an accident. • If this unit is installed under a front seat, make sure it does not obstruct seat movement. Route all leads and cords carefully around the sliding mechanism so they do not get caught or pinched in the mechanism and cause a short circuit. Care and maintenance • When the product gets dirty, wipe dry with a silicon cloth or soft cloth. If it is seriously stained, remove stain with a cloth moistened with a neutral cleaner and then wipe the cleaner away. Do not use a hard cloth and/or a volatile substance such as lacquer thinner or alcohol, scratches, deformation, degradation and/or damage may result. • When a lens component gets dirty, wipe gently with a soft cloth moistened with water. Do not rub with a dry cloth to prevent scratching the lens. Installation Procedure This section is for the professional installer. For safety's sake, leave wiring and mounting to professionals.
