The controller for my M600 Pro unfortunately had to be replaced; and I am trying to Link the new remote I purchased.  Looking at the Manual the instructions for linking say to press the Link button on the Lightbridge 2 system, and has a line drawing of what it would look like.  I am looking around the M600 and do not see anything that looks like the diagram.  Could anyone point me in the right direction as to where that piece is located? I'm sure it's a simple thing and I'm just looking right past it, so apologies for the question but I couldn't find an answer on Google or YouTube either.
Thanks in advance!

good day mcharron32. Just want to find out. Did you manage to find the link button on the dji matrice 600 pro?
