Note:
1. Before adjusting the balance, the camera needs to remove the lens cover and insert it into the memory
card to complete all the connections to ensure that the camera is ready to shoot.
2. During the balancing process, ensure that the camera power is turned off and the stabilizer motor is
turned off. It is possible to lock each axis of the stabilizer to the installation posture to facilitate balance
adjustment.
3. Tripods can be installed (refer to 20 pages for installation) for easy balance adjustment.
Unscrew the locking screw of the tilt axis motor and adjust the balance by
adjusting the sliding arm left and right (see Figure 7, Figure 8). When the cross
arm is kept horizontal, the camera lens is placed vertically upwards and stays
in a vertical state with the ground. The sliding arm adjustment is completed,
as shown in Figure 6.
（1）Adjust the position of the camera's tilting axis up and down: Place the
camera lens upright and keep the cross arm horizontal, as shown in Figure
