The best way to set the filter controls is through the use of a real-time spectrum analyzer and the expertise of a professional installer. This manual will guide you through the basic operation, however we suggest you refer to your Dealer for further information on the use of this unit. To access the Amplifier Controls and Switches refer to "Removing the Glass Panel" located on page 6 of this Owner's Manual. [. . . ] Replacing the fuse, if there is problem in the amplifier, may incur a risk of further damage. Refer to figures 10, 11 and 12. Caution: Disconnect the Amplifier from the Vehicle Battery ( or DC Power Supply) as Potentially Dangerous Currents exist inside the amplifier. Remove Top Cover Screws Figure 10 1. Before accessing fuses, disconnect both the positive and negative power cables from the DC input terminals on the left side of the amplifier using a 5/32" hex key. Remove the Top Glass Panel by first removing the four hex bolts with the supplied 3/32" hex key. [. . . ]
