Joystick locked in brand new Herelink

Hi,
I had bought a brand new herelink radio from a distributor. While checking it, the second joystick ( Right side) is not moving down ( Pitch down ). Will there be any lock inside the joystick, that I have to remove?

Sadly no it’s a Hw issue.

ok.

There is a screw inside which is loose not allowing free movement of the joystick. Had the same issue in one of our new herelink. Had to open and tighten it.
