Minimum Brightness Adjustment for LED Intelligent Dimmers
The light output of some LED lamps may appear to be too dim or invisible when the dimmer knob is at the minimum dim level. Follow the
steps below to adjust the minimum brightness level. This feature is primarily for adjusting the minimum brightness level of the LED lamp
although it can be used for other load types.
For a double gang dimmer, the light level of each gang has to be adjusted separately.

movement for 15 seconds. The dimmer will restore its factory default light level.
