Section 7 Troubleshooting
This section contains a list of possible error messages and a troubleshooting process for each.
7.1 Error
Messages
Table 7–1 lists the error messages that are displayed on the VFD of the receiver as well as the message sent
to the printer. There are two types of error messages that are displayed and printed, line card
communication errors, and system event errors. Line card communication errors relate specifically to how
the receiver communicated to an incoming call. System event errors relate specifically to the system and the
performance of its peripheral devices such as the automation software, printers, etc. In Table 7–1, heading
“LC Error” indicates that the error message was a line card communication error and “SYS Error” indicates
any system event related error messages.
