solutions.
Problem: A port light on an analog port interface does not
illuminate, although there is a panel attached to that port
1. Check the panel and the wiring leading to it.
2. Check the Frame Data light. If there is no indication of matrix
communication to this interface while the other interfaces in the
matrix are communicating, reset the interface.
3. Replace the interface cards.
4. Replace the panel.
Problem: Audio sounds low or distorted from a panel
1. Check the matrix’s currently active CPU card’s power lights. If any of
the lights are not lit, replace the card.
2. Check the analog port input and output gain settings for the port in
ECS.
3. Check the panel’s listen-level adjustment settings in ECS.
