		The cursor keyboard has holes that fit over locating pins in the front panel casting.
CAUTION		PREVENT GLASS BREAKAGE!
		Use care when handling the Lens Glass and the FPD monitor to prevent glass breakage.
		Inspect the inside surfaces of the Lens Glass and the Display Monitor closely for dust, smudges,
		and finger prints. Viewing these with line-of-sight 45 degrees to the surface is the best method
		for seeing subtle faults. Clean the inside surfaces with glass cleaner and lint-free lens paper before
		re-assembly. Clean the front of the FPD monitor by applying the glass cleaner to the lint-free
		lens paper or soft lens cloth. Do not apply glass cleaner directly to the FPD monitor. This will
		prevent cleaner from corroding FPD connections.
