How to connect boscam ts5830 transmitter to boscam fpv galaxy d2?

I have a dji phatom 2 and as it takes a gopro hero 4 for the camera I am trying to get a signal from the boscam TS5830 transmitter on the drone to the boscam fpv galaxy d2 but cant seem to find the right setting to recieve a picture?

P.s not the most tech savvy guy.

Thanks!
