Diagnosing LED Indicators
The Switch can be easily monitored through panel indicators, which describes
common problems you may encounter and where you can find possible solutions to
assist in identifying problems.
If the power indicator is not lighted when the power cord is plugged in, you may have a

power outlet. If you still cannot resolve the problem, contact your local dealer for
assistance.
