Installation and Debugging
The DJI O3 Air Unit is integrated with a transmission module and a camera module. Compared with the last generation DJI Digital FPV System, the size of the DJI O3 Air Unit is reduced by 40%, while the power consumption is increased by 40%. Due to its heat dissipation requirements, ventilation and heat dissipation measures must be taken during installation and debugging in order to avoid the equipment overheating or abnormal use. The installation method will also affect the cooling effect of the device.

I. Installation and Debugging Instructions:
1. DJI O3 Air Unit standby time: 8 mins (in 25°C/77°F environments), 5 mins (in 35°C/95°F environments).
2. When installing the DJI O3 Air Unit, make sure that the RX and TX are properly connected to the flight control board.
3. The DJI O3 Air Unit has two sets of temperature control strategies for the standby state and the flight state. It can apply different temperature control strategies according to the current state.
a. In the standby state, the protection system will be activated to automatically shut down the air unit when the temperature threshold is exceeded.
b. In the flight state, there will be a prompt alert when the temperature threshold is exceeded, and the video recording will terminate. At this time, the video transmission will remain connected, and the aircraft will have approximately 30 seconds to return and land. If the internal temperature of the IC board continues to rise, the protection system will be activated to shut down the air unit automatically.

II. Installation Suggestions:
1. The basic principle is to facilitate heat dissipation.
2. It is recommended to install the air unit in a position close to the propellers (distance between the air unit and the propellers within 10 mm), so that the downwash airflow can be effectively utilized. Try to avoid an installation position far from the propellers.
3. It is recommended to use a heat-conductive material to connect the frame and the air unit. This will dissipate heat to the carbon plate and the other non-conductive metal components of the frame. Conducting heat will extend the operating time.
4. Do not install the air unit in an enclosed area.
5. After the air unit is powered on, its metal shell will become hot. Therefore, the air unit should not be installed in a position easily accessible or held by hand.
Mechanical vibration at certain frequencies may result in abnormal EIS performance of DJI O3 Air Unit. The principles are as follows:

I. IMU Resonance The usual ESC PWM control frequency is 24 kHz by default, and the camera IMU frequency is approximately 24-30 kHz. If there is no effective vibration absorbing measure, the motor vibration may be transmitted to the camera IMU, causing resonance because the frequencies coincide. The resonance will affect the IMU data accuracy and EIS performance of the video stabilization application.* As a result, the processed video image shakes, but the live view image is not affected. Usually, frames with TPU or vibration-absorbing rubber are not prone to IMU resonance.
* Video stabilization application refers to either the DJI O3 Air Unit EIS function or third-party video stabilization software.

II. Propeller Vibration
If the rolling shutter effect appears in both the live view and the video image, it is usually because the propeller vibration (frequency is approximately a few hundred Hz) is transmitted to the camera through the aircraft frame.

Follow the steps below to troubleshoot and fix the image stabilization issue:
Step 1: Rule out the IMU resonance issue.
1. Remove the propellers from the aircraft. Make sure that the camera is securely mounted and the aircraft is placed in a stationary position on the ground. Then, enable RockSteady and start recording.
2. Start the motors and slowly push the throttle to the full throttle position. Observe the live view in the goggles. If the live view is not shaking, stop the motors and stop recording. Otherwise, check the camera and make sure that it is securely mounted.
3. Export the recorded video and check it. If the video image shakes, the issue is most likely caused by the resonance between the frame and the camera IMU.
In this case, refer to the following solutions:
a. Change the ESC PWM control frequency to 48 kHz or 96 kHz and test again.
b. If the video image shakes after solution a is adopted, apply a softer vibration-absorbing structure between the camera and the aircraft frame. Repeat the above testing procedures until the video image does not shake.

Step 2: After ruling out the IMU resonance issue, check if the video image has the rolling shutter effect caused by propeller vibration.
1. Install the propellers back and make sure that the propellers are not damaged. Fly the aircraft and start recording with RockSteady enabled.
2. Check the video image after the flight. If the video image does not have a rolling effect, the debugging is completed.
3. If the video image has a rolling shutter effect, try the following solutions:
a. Adjust the vibration-absorbing structure between the camera and the aircraft frame again.
b. Adjust the tightness of the screws that fasten the camera to the aircraft frame.

If the issue still exists after all of the above methods are completed, contact DJI Support.
The camera module can be fixed using screws. There are M2.0 standard screw ports on both sides of the camera, which are compatible with standard M2.0 screws on the market. Users can purchase corresponding screws according to actual needs.
The purchase of a DJI O3 Air Unit camera module includes four 4mm M2.0 screws.
Users can purchase the DJI O3 Air Unit camera module through the DJI Store online and replace it by themselves, or contact DJI After-Sales Service for repair. The replacement steps are as follows:
1. Purchase a new DJI O3 Air Unit camera module. (Do not disassemble the camera modules from other transmission modules. Those camera modules are bound to their corresponding transmission modules which may cause problems such as abnormal activation and issues during use.)
2. Follow the instructions in the user manual to remove the damaged camera module, and then replace it with a new camera module.
3. Use an external power supply to power the DJI O3 Air Unit and connect it to a PC via the USB-C cable. Launch DJI Assistant 2, and the device interface will display a prompt for updating the camera calibration file. Click to confirm and wait for the calibration file update to complete. (If the camera module malfunctions, you can also try this method to restore the camera calibration file.)
4. After the calibration file is updated, restart the DJI O3 Air Unit. Click the device icon on the home page of DJI Assistant 2, and then follow the prompts to activate the device to complete the replacement.
