Question

I use AG-DVC7 and a AG-DVC, my question is, the AG-DVC7 keeps shutting down if I keep it on pause to long. I use this as part of a 2 camera system recording on a deck (not on the camera tape) I do not see anything in the settings to stop this from happening, can you offer any advise?
Thank you.
