Flashing orange light means that there is no signal being received by the Victor from the receiver. Check the orientation of the black/red/white booster cable where it goes into the Victor, this could possibly be the wrong way round. The white wire should be on the outside edge.

Double check that, and confirm you've got the PWM booster cable and then let us know what happens. I would type a list of possible other things to check just now but I'm slightly inebriated and very tired so it can wait till we see if you're still having problems
There shouldn't be much to do in the way of calibration though. I seem to recall I was able to use my Victor pretty much straight out of the box.
