Notes:
(1) Skip this chapter if you purchase the Phantom 2 version of H3-3D gimbal, as it does not come with GCU.
(2) GCU must be connected to the flight control system before it is powered on.
(3) Be sure to mount the camera onto the gimbal before power on the aircraft and the gimbal. Otherwise it
might damage the servo due to the incorrect center of gravity setting.
(4) Re-calibrate the remote controller when NAZA-M firmware is upgraded.
(5) Ensure all the connection is correct, otherwise it might causes damage to the gimbal or the flight control
system.
GCU can either be vertically or horizontally installed on the Phantom 2. Follow the procedure below to complete
the connection between the GCU and flight control system.
Step 1. Upgrade the firmware of the flight control and the Assistant Software to the latest version (as shown in the
