I have been trying to unlock the Unify Pro Race Edition, but this thing won't unlock, how do I do it? 
I've tried holding the button in for 20 - 35 seconds and nothing happened, the orange led turned on and when I let go the blue one comes on? 
But if I use the smart audio settings on my taranis I can choose 25 200 500 and 800?

Here is the process for the future and any one interested. press longer.

Sequence:

1) Power up quad
2) press 3s long, let go (to enter the channel setting menu)
3) press 3s long, let go (to enter the band setting menu)
4) press until the double-lights come on, and then go off (about 25 seconds)
5) press 3s long to save and exit the menu


I think the main error I see, is people don't know they need to be in band selection mode to actually unlock the vtx. This means you need to complete step #3 above before attempting to hold the button to unlock the vtx. Or, they unlock it, change power, and then forget to exit the menu. The vtx will not save settings if you don't exit all the way back out, and the only way to do that is to finish through all of the modes.

It took me a min to figure out the unlock. They tell you you need to be in band mode to relock it, but not that you have to be in band mode to unlock it. scratched my head a good 45 min non that one.

The initial instructions aren't clear but if you scroll to the flow chart it makes more sense
