The switch matrix, on the left side of the display, shows the state of all switches. A dot indicates
the switch is open, and a square indicates the switch is closed. The numbers assigned to each switch
indicate where the switch is located in the matrix. The number on the left indicates the column, and the
number on the right indicates the row. Example: Switch 23 is 2nd column, 3rd row.
A short to ground, on either the row or column wire, appears as a shorted row(s). However, a
column wire shorted to ground disappears when all the indicated row switches are open. A row wire
shorted to ground does not disappear.
A shorted diode in the switch matrix can cause other switches to appear closed. These
"phantom" switches (though not actually closed) complete a rectangle in the switch matrix. Therefore, if
two switches in the same column are closed (example; #22 and #24), and a third switch is pressed in
another column but in the same row as one of the first two (example; #32), the "phantom" switch #34 is
falsely indicated as closed. The switch with the shorted diode is diagonally opposite the "phantom "
switch (in this case #22).
T.1 Switch Edges
Press each switch one at a time. The name and number of the switch is
shown in the display. If a switch other than the one pressed, or no switch at all is indicated, the
system has detected a problem with the switch circuit.
T.2 Switch Levels
This test automatically cycles through all switches that are detected
closed. The name and number of each switch that is detected is shown in the display. A filled
square indicates the switch's position in the matrix.

T.3 Single Switches

from all other switches. Use the Up or Down buttons to select the switch to be tested.
