Before installation
Before installation of this unit, please note the following precautions.

WARNINGS · If you connect the ignition wire (red) to the negative

ground point, you may cause a short circuit, that in turn may start a fire. Always connect those wires to the power source running through the fuse box. · Do not cut out the fuse from the ignition wire (red). The power supply must be connected to the wires via the fuse.
NOTE
· Mounting and wiring this product requires skills and experience. For best safety, leave the mounting and wiring work to professionals.
· Make sure to ground the unit to a negative 12V DC power supply.
· Do not use your own screws. Use only the screws provided. If you use the wrong screws, you could damage the unit.
· If your vessel 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 front panel will not hit the lid when closing and opening.
· If the fuse blows, first make sure the wires aren’t 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 on 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 vessel.
· When only two speakers are being connected to the system, connect the connectors either to both the front output terminals or to both the rear output terminals (do not mix front and rear). For example, if you connect the ¢ connector of the left speaker to a front output terminal, do not connect the ¤ connector to a rear output terminal.

· After the unit is installed, check whether the signal lamps, wipers, etc. on the vessel are working properly.
· Reception may drop if there are metal objects near the Bluetooth antenna.
