ClearNav Vario Spoiler Warning

I finally completed installation of my new CNv XC vario and am having
problems with the gear/spoiler warning logic.

In my installation, while sitting on the trailer, opening the spoiler
causes the Spoiler warning to flash and sound off. This happens without
respect to the gear position or switch reading. Reading the switches in
the Info section of the CNv, I see that both switches are correctly
wired and functioning (both show 0 and 1 status as appropriate).

Is it possible that this is a ground test function and I won't know if
everything works as intended until my first takeoff?
