[. . . ] If you must replace a fuse in your Marine amp, use a fuse of exactly the same type and rating. Us, ng a different type or rating of fuse may result in damage to your amp or marine vessel or cause a fire. Protection Circuitry This amplifier incorporates special protection circuitry Which will disable the amplifier if any of the following should occur: · Input overload · Short circuit Before you drill or cut any holes, investigate your car's layout very carefully. Take special care when you work near the gas tank, fuel lines, hydraUlic lines and electrical wiring. Attach all audio system components securely within the amplifier to prevent damage, especially in an accident. [. . . ] Do not mount this amplifier so thai wire connections are unprotected, in a pinched condition, in contact with any metal surfaces in your marine vessel, or likely to be damaged by nearby objects. Before making or breaking power connections in your system, disconnect the marine vessel battery. Confirm that your head unit or other equipment is turned off while connecting the input jacks and speaker terminals. If you need to replace the power fuse, replace it only with a fuse identical to that supplied with the amplifier. Using a fuse of a different type or rating may result in damage to your audio system or your amplifier which is not covered by the manufacturer's warranty. · Do not open or attempt to repair this unit yourself. Dangerous high voltages are present which may result In electric shock. Refer any repairs to a qualified service technician. · To avoid risk of electronic shock or damage to the amplifier, do not permit any of this equipment to become damp or wet from water or drinks. If this does occur, immediately unplug the power wires and send the amplifier to your local dealer or service center as soon as possible. · Extremely high temperatures If any of these conditions Is detected, the amplifier will go into a self preservation mode, and the PROTECT LED on the model number badge on top of the amplifier will be illuminated. What should I do if my amplifier PROTECT LED is illumInated? · If there is smoke or any peculiar odor present during use or if there is damage to any of the component enclosures. immediately unplug the power cord and send the amplifier to your local dealer or service center as soon as possible. If you observe that the PROTECT LED is on, please check the system carefully to determine what has caused the protection c1rcuit to engage. To reset the amplifier when it is in PROTECT mode, turn the power off to the system (usually by turning off the head unit or other signal source which feeds the amplifier) and then turn it on again. If the shut down was due to either an input overload or a short circuit, be sure to correct these conditions before attempting to power up the amplifier again. SHOCK HAZARD!There are no user-serviceable parts within the unit. MarIne MOSFET Amplifier User's Manual - page 5 Martnc MOSFET Ampllftor User's Manual· page 4 Mounting the amplifier 1.
