use a file to square the corners and smooth any ir- regularities in the cut edges, 5. Install the Mounting Strips In the hardware package you will find two mounting strips and two sets of machine screws. For panels that are less than ½ inch (12.7 mm) thick, use the ¾ inch (19.1 mm) screws; for panels that are more than ½ inch (12.7 mm) thick, use the 1¼ inch (31.8 mm) screws. Starting at the right-hand side of the panel, insert a screw of proper length into the center hole in the panel, marked B on the template. On the back of the panel, align a mounting strip with the holes in the panel and tighten the screw in the center hole until the screwhead is pulled slightly into the wood. Repeat this procedure to attach the mounting strip to the left side of the panel. 6. Attach the PANLOC Brackets Using two screws of proper length in the A holes on each side, attach the PANLOC brackets to the cabi- net panel; the short flange is mounted against the front (face) of the cabinet panel. The screws pass through the PANLOC bracket flange, the cabinet panel, and then through the mounting strips previously mounted. 7. Install the Instrument Guide the AC power cord through the panel opening to the back of the cabinet; then, slide the instrument into the opening carefully so that the rails on the bottom of each side of the chassis engage the tracks on the mounting brackets. Continue to slide the instrument into the cabinet until it is stopped by the adjust position latches. Press the latches in- ward, this permits the instrument to slide into the cabinet until its front panel is flush with the cabinet panel. Depress the PANLOC buttons at the lower left and right corners of the instrument panel to lock the unit firmly in the cabinet. Depressing the PANLOC buttons again will unlock the instrument so that it can slide forward to the adjust position; if you press inward on the adjust position latches then you can remove the instrument from the cabinet. -5-
