Connecting the <DC OUT> terminal with the external recording start/stop switch

It is possible to retrieve 1.5 A current from the <DC OUT> terminal of the camera.

Recording start/stop can be controlled by connecting an external switch to this terminal.

An LED connected to this terminal can also be used as a tally lamp. This is useful for shooting video when fixing the camera on a crane.
