If the Mini 4 Pro has been updated to C1A1 it should broadcast Remote ID and show the GEO Zones.

Can the pilot  turn off the Remote ID / activate the Remote ID according to the flight intentions and circumstances.
e.g. Standard we can fly in C0 (so without Remote ID) outside the restricted zones, but if necessary and compliant to the restrictions by the zone one should be able to activate the Remote ID;

Thx for more information as I hesitate to submit my request for up/down-grading my DJI Mini 4 Pro from the standard C0 to C1

Hi there, thank you for reaching out. Yes, the DJI mini 4 Pro will support the RID function after being C1 certified. However, once it is upgraded to C1, the certificatecan't be downgraded. Once the aircraft is C1 certified, it will start broadcast the remote ID which can't be turn off.

Thank you for your understanding and support.
