Always start the gimbal with a balanced camera set up otherwise after
initialization the controller will return an error followed by a red color
indicator.
If the status LED is solid red, something is wrong with the gimbal and
motors can not start. Connect to the software/apps to check details of
the error message.
Make sure the Hyper Quick Release is mounted to the drone and its power port is
already connected to the power supply correctly. Next, let’s mount the gimbal to
the Hyper Quick Release, it will be automatically powered up.
Wait about 2 seconds, do not touch the gimbal or camera.
If the status LED is blinking green, the gimbal is ready for use. By default, the
gimbal is in Follow mode if the motors are turned ON by the Function Button.
Read “LED STATUS INDICATOR” in next section for more information.
