Install the unit in your vessel.7. Reconnect the - battery.8. Press the reset button.2WARNINGIf you connect the ignition wire (red) and the battery wire(yellow) to the negative ground point, you may cause a shortcircuit, that in turn may start a fire. Always connect thosewires to the power source running through the fuse box.¤• Mounting and wiring this product requires skills andexperience. For safety’s sake, leave the mounting and wiringwork to professionals.• Make sure to ground the unit to a negative 12V DC powersupply.• Do not install the unit in a spot exposed to direct sunlightor excessive heat or humidity.• Do not use your own screws. Use only the screws provided.If you use the wrong screws, you could damage the unit.• If the power is not turned ON (“Protect” is displayed), thespeaker wire may have a short-circuit or touched thechassis of the vehicle and the protection function mayhave been activated.

Ifthe receiver is left on for an extended period of time thebattery may die.• If the fuse blows, first make sure the wires aren’t touchingto cause a short circuit, then replace the old fuse with onewith the same rating.• Insulate unconnected wires with vinyl tape or other similarmaterial. To prevent a short circuit, do not remove the capson the ends of the unconnected wires or the terminals.• Connect the speaker wires correctly to the terminals towhich they correspond. The unit may be damaged or fail towork if you share the - wires or ground them to any metalpart in the vessel.• When only two speakers are being connected to thesystem, connect the connectors either to both the frontoutput terminals or to both the rear output terminals (donot mix front and rear).
