“Wiring OK Indicator” LED is not illuminated.
Probable Cause: There are 3 reasons why this LED would not be illuminated:
1.Reversed polarity exists at the wall outlet.
2.Neutral wire is overloaded.
3.Earth ground is missing at the wall outlet.
Solution: Operating the unit under such conditions may impact its surge protection performance. Contact an electrician to have them inspect the building or home wiring to fix the problem.
Probable Cause: Unit is on but LEDs are turned off.
Solution: Push the Setup button, push the Select button two or three times. The LEDs should illuminate. Choose the dimmer setting (see the sections on “Front and Rear Panels” and “Setup the H10”).
