Specific Troubleshooting Examples

The following examples describe specific problems and suggested
solutions.
Problem: A port light on a port card 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 card while the other cards in the matrix are
communicating, reset the card.
3. Replace the card.
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 port card's input and output gain settings in the program
software.
3. Check the panel's listen-level adjustment settings in the program
software.
