4.1 Troubleshooting
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 Hybrid IP-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-TDA15 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-TDA15 Maintenance Console
