check the unit in another mode.

troller
1. If the unit is in DMX mode and the first digit of the dis‐
play flashes, no DMX signal is received. Check that the
DMX controller is switched on. Check the DMX connec‐
tors and cables for proper connection.
2. If the unit is in DMX mode and a DMX controller is
connected and turned on, the first digit of the display
will light constantly. If it doesn't, no valid DMX signal is
received. Check that the DMX controller is switched on.
Check the DMX connectors and cables for proper con‐
nection.
3. If the first digit of the display lights constantly but
there is still no response, check the address settings and
DMX polarity.
