6.2 Fault Isolation
Once the terminal has been set up for operation, troubleshooting faults can be
accomplished by monitoring the terminal faults either remotely or via the optional front
panel/keypad and display.
System faults are reported in the FAULT menu.
Table 6-3 should be used to isolate problems and determine the appropriate actions to be
taken.
