For DMX mode: Return the DMX control to 0.

For AC mode: Remove the fixture from power for five seconds and then restore power.


Indicates the fixture has gone into under-temperature protection. Allow the fixture to warm to a minimum of 5°C (41°F).

Flashing DMX Address

Indicates loss of DMX.

Dark Screen

Indicates loss of power or fixture time-out. In the event of time-out, press any button to wake the user interface.

dL / rdy
