(Pages 51 - 54) Before installation Precautions on installation and connection • Mounting and wiring this product requires skills and experience. For best safety, leave the mounting and wiring work to professionals. • Mount the unit so that the mounting angle is 30° or less. • Make sure to ground the unit to a negative 12 V DC power supply. • Do not install the unit in a location exposed to direct sunlight or excessive heat or humidity. Also avoid places with too much dust or the possibility of water splashing. • Do not use your own screws. Use only the screws provided. If you use the wrong screws, you could damage the unit. • After the unit is installed, check whether the brake lamps, blinkers, wipers, etc. on the car are working properly. • Do not press hard on the panel surface when installing the unit to the car. Otherwise scratches, damage, or failure may result. • If the power is not turned on ("Miswiring DC Offset Error", "Warning DC Offset Error" is displayed), the speaker wire may have a short circuit or have touched the chassis of the car and the protection function may have been activated. In this case, the speaker wire should be checked. • Keep all cables away from heat dissipating metal parts. • If your car's ignition does not have an ACC position, connect the ignition wires to a power source that can be turned on and off with the ignition key. If you connect the ignition wire to a power source with a constant voltage supply, such as with battery wires, the battery may be drained. • If the console has a lid, make sure to install the unit so that the monitor panel will not hit the lid when closing and opening. • If the fuse blows, first make sure the wires are not touching to cause a short circuit, then replace the old fuse with one with the same rating. • Insulate unconnected wires with vinyl tape or other similar material. To prevent a short circuit, do not remove the caps and do not let the cable out at the ends of the unconnected wires or the terminals. • Secure the wires with cable clamps and wrap vinyl tape around the wires that comes into contact with metal parts to protect the wires and to prevent short circuit. • Connect the speaker wires correctly to the terminals to which they correspond. The unit may be damaged or fail to work if you share the · wires or ground them to any metal part in the car. • When only two speakers are being connected to the system, connect both connectors either to the front output terminals or to the rear output terminals (do not mix front and rear). For example, if you connect the ª connector of the left speaker to a front output terminal, do not connect the · connector to a rear output terminal. ENGLISH 49
