[. . . ] The SHELF CUTOUT TEMPLATE is marked for front panel thickness from ¼ inch to 1 inch. Fold the template on the line that corresponds to the thickness of the particular panel being used. Place the folded template on the shelf, butted against the back side of the front panel. Match the center line on the template to the scribed center line on the shelf. The shelf center line should also exactly meet the vertical center line used to make the front panel cutout. 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. 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. 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. The four 10-32 x % inch screws used in shipping the tuner are also used to mount it to a shelf of ½ inch or 5/8 inch thickness. [. . . ] Adjust the tuning meter thumb wheel control again if necessary to re-center the meter pointer in the black area. If the meter pointer moves an appreciable amount on the first test, the second adjustment is necessary for precise meter operation. When the meter circuit is properly adjusted the meter pointer should stay centered in the black scale area when the AUTO FREQ CONTROL is turned from MIN to MAX. When the FM tuning meter is adjusted by this procedure, precise FM tuning is insured with the meter pointer centered in the black scale area. [. . . ]
