2.1 What Is in This Chapter?

Introduction In the first stage of the troubleshooting sequence, it is important to correctly interpret the error code on

the remote control display. The error code helps you to find the cause of the problem.

Shutdown For some errors, the system only shuts down when the error occurs several times. This means that

you have to wait until the system shuts down to be able to see the flashing LED on the front panel and

the error code on the remote control.
