Actually DJI do not say that ...
What they say is : Always calibrate the compass in every new flight location.
Also they say on same page (page 41 of the manual) : DO NOT calibrate your compass where there is any possibility of strong magnetic interference .... etc.
I would suggest qualifying that statement about new location .... when of significant distance from previous calibration location.... and I am talking miles not m's !!
