Co-Pilot 2 preflight error messages

[OYLORE]

I arm my T-Rex 450 pro indoor! When I do Preflight check I got this messages:

Warning system error! Weather Poor for Flying Co-Pilot
(enter)
Batt = 6.01 V
Warning! < 4.12 V
(enter).....
Pitch = - 36.0 DN
Roll = + 33.2 Lft

I have done Quick Setup but did not get 98% on eil and elev. I got ca 90%

What do I do? Are this messages because I arm my heli indoors?

Indoors is no good for CPII;).

pril is correct, take it outdoors and try it

I hang it off the tail gate of my truck (CP) :D so the vertical sensor can see sky & ground for a reading.

Only seen 2 times for a "fly if you want, but not sure if I can save you today Mel" readings..

Thanks!

Started systems outdoors this weekend and everything worked perfectly.
