CAUTION

The hinge cover is molded to be installed one way with the little slope facing the top cover, see insert "C"

of Figure 4-1; if it is installed backwards the cover will not close. Attempts to close the cover will break the

display assembly and the ANCD will have to be replaced. Do not over tighten the screws as damage will

occur to the hinge assembly requiring the replacement of one or both cover plates.
