Atlas GP40-2 Flashing Hood Light

Hello All

Pulling my hair out trying to get the Low Nose headlight on my GP40-2 Gold to flash like a gyralight.

The one I have is a CSX http://www.atlasrr.com/holoco/hogp40-2a.htm. They have a youtube link showing it flashing. So far I tried the mars light settings at 55.76.X with no luck. Am I changing the wrong settings?

The decoder is factory Quantun Q1A Software version 7

Any Ideas?

Thanks
