OSD joystick is 5-way. Means you can move it into 4 directions + press down. To enter into settings OSD, you need to press down the OSD joystick ?? then navigate to the language settings and set the English language. See video of OSD example in the review.

Thank you so much!
I finally got it working ??
You are the man!
My next problem is how do you get the osd to work? :’D
Really sucks that it ships with no instructions

Usually you connect GND wire the device, which provide +5V power for the camera. It can be VTX, PDB, FC. Any ground plane fits. BUT! If you experience interference lines (diagonal, horizontal) then you could try to connect GND wire as closer to the lipo battery leads as possible. But even in this case do not connect camera red wire (+) to the lipo directly, only black ground wire (GND).

Thank you so much for a quick response!
The black wire to the ground.. is this to the vtx or lipo? Sorry a lil bit of a noob ??

Camera comes with 3 pin servo plug. Just connect yellow wire to the video signal inpot on TX, red to +5V source and black to the ground. I recommend to use +5V pover source. Yeah, the voltage range 5-15V is not enough for 4S battery, do not connect to the battery directly.
