C-20 User Manual Installation O3 Version 1. Remove the housing fixing screws of the camera (one on each side) and separate the front and rear housings of the camera. Do not separate the housings too far or may damage the camera. 2. - Page 9 C-20 User Manual 4. Install the lens protection ring on the front of the lens mount. 5. Fix the lens into the lens mount with four M1.4 x L3mm screws. The mounting direction of the lens in the lens mount is unique. Please note the correspondence between the lens locating posts and the locating holes inside the lens mount.

- Page 13 C-20 User Manual Controlling the C-20D The C-20D supports Headertracker direct control, S.BUS / CRSF control, PWM control and MAVLink control, with the priority of the four control methods above decreasing in order. The gimbal automatically switches upward / downward mode according to its attitude at power-up.
- Page 14 C-20 User Manual Gimbal Modes There are three operating modes of the C-20D as below: FPV Mode (Mode 0) All three axes follow the movement of the carrier with eliminating slight shaking. Horizon Mode (Mode 1/2) Only the yaw axis follows the movement of the carrier with eliminating slight shaking.
- Page 15 C-20 User Manual Configuring, Calibrating & Firmware Updating Configure the gimbal and update firmware of the gimbal with the GimbalConfig software. Ensure the driver of the Config Module is installed on the computer before configuring, calibrating or updating. Connect the Gimbal 1.
- Page 16 Click "Save Param To Flash" to finalize the configuration into the gimbal. Parameter Tuning For cameras with larger moment of inertia, mounting them on the C-20D may result in gimbal shaking. In such cases, increasing the gain value can enhance stabilization effects.
