POWERING UP
THE MIO
If there is a remote-control signal, changing modes or turning motors
on/off by other methods will not take effect because the remote-control
signal has the highest priority and will override the command.
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 the 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.
Read “LED STATUS INDICATOR” in next section for more information.
NOTE

SINGLE OPERATOR: using FOLLOW mode.
DUAL OPERATOR: a second operator can use a Remote Controller (SBUS,
PPM) to control gimbal’s movement.
OPERATION MODES
LOCK MODE: is a stabilization mode where the camera maintains orientation
independently of the rest of the gimbal and the orientation can be changed by an
external control signal from remote control.
FOLLOW MODE: in this mode, the camera will mimic the operator’s movement
and allows one person to control camera tilt and pan without using an external
device like a remote control.
