The GNC 420's display is divided into three separate "windows" (or
screen areas). The left 1/4 of the display provides a COM window (top two
lines) and a user-defined data field below. The right 3/4 of the display con-

settings pages. The bottom of the display is used for annunciators.
Each unique screen of information is referred to as a "page". Pages are
typically selected using the small (
