Why does the XAG XMission indicate camera missing or SD card missing?

1. Check whether the firmware version is updated to the latest version, then restart the APP and the XMission.
2. Gently wipe the socket with a soft rubber eraser and replace with another camera or SD card (the XMission is a highly integrated device, so you MUST power it off before attempting to change the parts. Keeping the machine on while swapping parts is STRICTLY PROHIBITED, as it will lead to severe damages to the PCB).
3. Clean up the camera's cache and restart the XMission and its app.
(If you still cannot solve the problem after trying the above steps, please return the equipment to the factory for inspection and repair.)
