4 Push the Marker A left and right arrow keys to highlight each LED symbol in the test
screen. Verify that the corresponding LEDs on the front panel are the only ones
illuminated.
Test by Rows
You can use the Marker B arrow keys to test LEDs by row; however, in the event that two LED indicators
are shorted together, there is a small chance that the test will not reveal the failure.
