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.
