Grasp the LCD Display (assembled with spacers, and fasteners in place) and carefully work it into the LCD Case [PP-IS0056]
It is helpful to lead with the left side as pictured and then carefully fit the right side around the lip inside the case.

Using a crisscross pattern, thread each flat head screw into the inserts on the bottom of the case.
Ensure all four screws have started properly before beginning to tighten.

Continue to tighten using a crisscross pattern until the edges of the LCD Bezel are at level with the lip inside the case; see [reference#1]

Install four M3x8 BHCS [HD-BT0137] with washers [HD-WA0038] into the four M3 holes on the LCD Cover [PP-MP0215]

Before tightening, center the LCD cover within the outer four edges of the LCD case for best appearance. Make sure there is enough clearance for the LCD knob and that the LCD knob post is centered in the hole in the cover. Tighten until the LCD Cover lays flat around the edges of the case.
Do not over tighten, this will cause the cover to bow inwards near the screw heads.
