How to Pair DJI Air Unit O3 with Goggles 2

I. Principles

The DJI AIR UNIT O3 video transmission requires pairing (binding) with DJI Goggles 2 before it can properly receive and display the FPV image.

II. Equipment Preparation

1) Flight Controller: Any of the SpeedyBee F405 WING APP / SpeedyBee F405 WING MINI / CoreWing F405 WING V2 flight controllers is applicable to this tutorial.
2) FPV Goggles: DJI Goggles 2
3) Video Transmission Device: DJI AIR UNIT O3
4) Power Source: Use a battery to power the flight controller or FPV goggles.

III. Procedure

1. Wiring the Video Transmission and Flight Controller

2. Pairing the Video Transmission and Goggles

1. Turn on the devices. Open DJI Goggles 2 and wait for the system to boot up. Turn on the DJI AIR UNIT O3 and ensure a stable power supply.
2. Enter pairing mode. Long-press the pairing button on the DJI Goggles 2 body; after hearing the "beep-beep" prompt sound, the goggles enter pairing mode. Short-press the pairing button on the DJI AIR UNIT O3 body and wait for the pairing to complete.
3. Confirm successful pairing. When the AIR UNIT O3 indicator light changes from green to red, it indicates that it has entered pairing mode. After successful pairing, the AIR UNIT O3 indicator light turns solid green, and you can see the O3 video transmission in the Goggles 2 display.
