4.12 The Maintenance\Test LC Display status screen
The RLS uses a four-line Liquid Crystal Display that displays 20 characters per line.
This status screen uses three different test screens to check the operation of the dis-
play. After selecting the Maintenance\Test LC Display screen, use either the (UP)
or (DOWN) key to select any one of the three test screens.
The first two test screens display the character set used by the RLS. The third test
screen checks the operation of all display pixels, by turning them all on or all off at
the same time (the screen blinks). When all of the pixels are turned on, the user
should see four lines of 20 solid rectangles each. When all of the pixels are turned off,
all four lines should be blank.
Press the EXIT key to return to the Maintenance menu.
