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 not 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.
