Diagnosing LED Indicators

The Switch can be easily monitored through panel indicators to assist in
identifying problems, which describes common problems you may encounter
and where you can find possible solutions.
IF the power indicator does turn on when the power cord is plugged in, you
may have a problem with power outlet, or power cord. However, if the Switch
powers off after running for a while check for loose power connections, power
losses or surges at power outlet. IF you still cannot resolve the problem,
contact your local dealer for assistance.
