I am noticing an "X" appear during the Korg GEC's self-test cycle. What does this mean?

This indicates that there is a bad connection between the GEC3 unit and one or more of the SCI (student) units. This can be caused by either a bad CAT5 cable or a bad SCI (student) unit. To determine this, do the following:

• Power down your GEC and wait 5 seconds
• Power on your GEC and properly identify which stations are indicating an "X" during the self-test cycle.
• Once you have identified a "bad" station, unplug the RJ45 connector on the rear of the station's SCI box and swap it with the RJ45 connector on a "good" station's SCI box.
• Power down your GEC once again and wait 5 seconds
• Power on your GEC and study the self-test cycle readout.

If you notice that the "X" of the suspected station has moved to the "swapped" station, you have a bad cable. If the "X" has not moved, you have a damaged SCI unit.
