5)The main optical unit is attached to the equatorial mount with a black cast metal mounting plate. This mounting plate has four chromed screws mounted in it. Remove all four screws. The mounting plate has one smooth face and one face with small ridges. Place the smooth face against the underside of the main optical unit. Then insert the two slotted chromed screws through the inner holes so that they engage with the two threaded holes on the underside of the main optical unit. Tighten these with a screwdriver (See Fig. 4).
