I have a big problem.
3 sets purchased Herelink HD.
Of the 3 purchased, 2 work well. (no complaints).
There is one set with a defect. (manufacturing defects)
The air part does not turn on.
No LED indication.
No connection land + air part.
The kit is new, just out of the box. (never been used).
Below I attach a video where you can see what the problem is.
