Place the fully populated PCB over the stands. Top side up. Center the screw holes directly over the center
of each nut.
Place a washer over
both
of the screw holes on the PCB.
Make sure that the nut has not slipped out. You will be
able to see it if you look directly through the hole, from
the top down.
Place the bezel over the PCB and washers.
The ‘reset’ side of the bezel, goes over
the button end of the PCB.
Slide a screw into each screw hole in the bezel.
Slowly tighten each.
Do not over tighten.
You may crack the acrylic.
