I learned that any of the three axis locks can result in the sleep mode almost immediately the motors sense the fact. So be careful when unlocking the locks.
I have more experience with the Sleep Mode now after shooting whole videoclip sessions. I did it with BM 6K pro that has got a tilting screen. That made some troubles using Moza Air 2S. If I grab the tilting screen for too long the gimbal turns into the sleep mode too fast.
How can I escape the sleep mode without turning the gimbal off and on?
The time of the sleep mode activation should be a little longer I guess.
