Using

NFZ mod board allows you to fly using GPS positioning inside NFZ zones.  By default NFZ mod is not activated therefore you can use your Phantom34 as usual. No NFZ correction will be applied.
Activate using Remote
Power on your remote. Before powering on the battery set throttle (left) stick on you remote to the bottom position and hold it for about 10 seconds after powering the Phantom battery. It will activate defaults NFZ offset. You can see position offset at your DJI Go screen after satellite position is fixed. Ensure that there is no fly zone near your false position otherwise restart battery and select other NFZ offset. You can control NFZ offset by moving stick to right or left during initialization.
Be very careful with NFZ mod activated. Avoid mixing false and real coordinates.

  • Don’t use Dynamic Home Point
  • Don’t set position as home point
  • Don’t use Follow me
  • Don’t fly by pointing coordinates on map

Firmware

USB port on NFZ board is for NFZ board firmware updates.  We’ll keep testing NFZ board with new Phantom 3 firmware releases, but it is better to avoid updating Phantom without any need.
