My Phantom 3 Pro manual refers to a "link button" and points to the side of the aircraft in one of the diagrams on page 29 to indicate its supposed location.  My bird has no such button.  How can that be?

There is a LED and a small hole just below the CE 1313 decal on the camera usb port side of the P3. Inside the small hole is the LINK press button referred to in the manual. The LED will flash on power-up and will be RED until a link is established, when the LED will then turn GREEN:

Thanks again Terry for greatly helping on the forums.

Thanks.  I see it now.  I was looking for a button one can press with a finger, not a tiny thing recessed into a small hole.
