List of Errors and Solutions
The tables below list the errors and their solutions.
When an error whose error code is indicated with "*" occurs in the PBX, the ALARM indicator on the front
of the cabinet turns on red, and the system logs the error information.
When the error conditions indicated by the error codes "021", "091", "092", and "510" are recovered, the
ALARM indicator will turn off automatically, indicating successful troubleshooting. When other errors are
logged, the ALARM indicator will turn off only when the log for major or minor errors is cleared from the KX-
TAW848 Maintenance Console.
In other words, the ALARM indicator will turn off under the following conditions:
• When the errors "021", "091", "092", and "510" are logged: when the error conditions are
recovered
• When other errors are logged: when the log for major or minor errors is cleared from the KX-
TAW848 Maintenance Console
