I just bought a new Quad Gem DMX, and when I turn it on, all the lights flash 4 times. Any way to turn that off?

There is no way to turn of this flashing since it is written in the program.

I think if you get yourself a UC3 remote controller & use the blackout mode, you can avoid the test pattern every time you want to use it. This way, you'll turn it on 1 time & let the test pattern blink on & off, then after that, you should be able to use the blackout mode on the remote for on & off without the test pattern running each time.
