I think grandparent comment means how to deactivate the recording indicator light: it seems it will not turn on if the camera starts recording and sees only black. Maybe to prevent light pollution for dark scenes/accidental recording? So the hack is to cover the camera, start recording, wait a few seconds, and then record normally, the indicator light will remain off (I write from memory, it could be more convoluted than this).

Or maybe the workaround is there like the simple workarounds on DVD players to bypass region-check: because the manufacturer knows info about it will spread and help sell the product.
