First Day Configuration Testing Rules

[MikePres]

Hi,
Our competition is in a week. we sent our robot with a certain configuration, we have a mechanism that is supposed to elevate us on the tower. the problem is that we didn't have time to test it. we have also a ramp mechanism and we intend to hang others with us on our ramp.
My question is - can we test our systems on day 1 (in the warming rounds) and if they don't work - remove them and not be with them for the rest of the competition? (this is all going to be before final inspection, of course) Is it legal? we have a plan B but we wanna use it if Plan A fails, but we need to test it first.
if you wonder, Plan B: we're going to use our ramp for others for easy driving up to the Platform. if we can't help ourselves, at least we'll help others^^.
(oh and BTW, i checked the manual, maybe i missed the relevant part).

thanks ahead
