Continuous beeping on take-off

[Mboy]

My MA2 has suddenly decided to beep continuously after take-off. This is in clear spaces, so not to do with proximity to objects. In any case, turning off the obstacle avoidance system doesn't stop the beeps. I have recalibrated the IMU btw. Still doing it. I can't see anything in the manual about this.
Everything else appears normal (ie., it's flying OK). It did flash a message on one occasion that the sensors were blocked (not the case). Am I missing something blindingly obvious?

Are you getting any visual indication on the screen of an obstacle.
I've also seen on here other people who have had the same issue
have resolved it by recalibrating the sticks. If you search the problem
on here there is quite a bit of advice on the subject.

I am getting a yellow bar, top and bottom of the controller screen, just checked, but that was indoors... This is happening in the great outdoors, though.

If you power on the remote with a stick off center it will do the beeping thing. The suggestion to recalibrate the remote sounds like a good one if you aren't accidentally leaning on a stick when turning it on like I was when I discovered it...
