Scribe the rectangular cutout for the ventilating hole. Drill the four ¼ inch diameter mounting holes and then cut out the rectangular ventilating hole. INSTALLING THE MR65B Remove the four 10-32 x % inch screws holding the MR65B to the shipping board. Save these screws since you will need them if your cabinet shelf is ½ inch or 5/8inch thick. Remove the four plastic feet from the bottom of the tuner. The mounting hardware package includes four 6-32 flat head screws and eight 6-32 round head screws. Two of the flat head screws of the proper length are used to attach the mounting strips to the cabinet panel. Four of the round head screws of the proper length are used to attach the tuner to the mounting strips and the cabinet panel. The 6-32 x ½ inch screws are used with panels under 3/8 inch thickness. The 6-32 x 1¼ inch screws are used with panels from 3/8 inch to 1 inch thickness. The edge of the strip with the clips must face toward the panel opening. Line up the mounting strips on each side of the panel cutout so the three holes in the strips are in line with the holes in the panel. Install two of the proper length flat head screws through the front panel and into the center hole of each mounting strip. Drive the screws in so the flat heads are flush with the panel. If necessary, countersink the two center holes. Figure 9. Securing the Mounting Strip to Front Panel. Carefully insert the tuner through the front panel opening so it rests on the supporting shelf. Insert the proper length round head screws into the four holes in the mounting flanges on each end of the tuner panel. Drive the screws in through the panel and into the threaded clips on the mounting strips. If the cabinet is fixed and will not be moved about, it is not necessary to secure the tuner chassis to the shelf. If the cabinet is to be moved about, it is recommended that the tuner chassis be secured to the shelf in the following manner. [. . . ] Set the switch to BRIGHT for maximum panel light.
