of the failure by reading out the log, and correct the
problem.
If necessary, check all connections using the PC
software. For log readout and connection check, refer
to
p. 11-7.
Tip
For most failure indications, the failure LED automatically
extinguishes when the cause has been corrected. For
certain other failure indications, such as power amplifier
failure or speaker shorts, the LED does not automatically
extinguish. In such cases, Failure Output Reset needs
to be performed.

Note
Make sure that the system's power is switched OFF if there is a chance of bodily contact with the internal
components or live parts of the equipment when investigating the cause of a failure. For procedures regarding
switching off the system power, refer to the Instruction Manual attached to the VX-2000DS/3000DS.
