Mounting the QSD 204 on the underside of furniture

1. Attach the mounting brackets to the QSD 204 decoder using the decoder’s existing top cover screws. See the above illustration.

2. Place the decoder against the underside of the furniture, then mark the location of the bracket screw holes on the mounting surface.

3. Drill 3/32” (2 mm) diameter pilot holes, 1/4” (6.3 mm) deep into the marked bracket screw holes on the furniture mounting surface.

4. Insert the four #8 wood screws into the four pilot holes. Tighten each screw into the mounting surface until about 1/4” of the screw head still protrudes from the mounting surface.

5. Align the mounting screws with the slots in the brackets and place the decoder flush against the mounting surface. Position the decoder forwards or backwards in the bracket slots, then tighten the four screws.
