Microraptor Pro Case - how to remove "O" ring

[Luckyguy]

I've read some threads on the Microraptor Pro Case and a few times people have mentioned that it is air tight and the case can collapse after pressurization and de-pressurization as a result of flying in planes while traveling. It's been mentioned that there is some kind of ring under a latch that can be removed to allow the air pressure to equalize from the outside to the inside.
I can't find any info in either the instructions, manufacturers website etc. Does anyone have a procedure for remiving this ring? And where on the case to find it? Thanks.

If this is the case that you have, it looks like the seal is in the top, see red dot.

It also appears that the case has no bleed valve.

My case has an automatic valve, where some have a manual valve that you twist to open and close.

Any sharp object like a dental tool should enough to remove it, but I'm not convinced that the case pressure ruined that guy's controller.

It looks exactly the same, even colors and compartment layout. But there is nothing by the red do in my case except the long gasket that runs al

Where is the automatic valve on yours?
Thanks

THE FEATURES SHEET THAT CAME WITH THE CASE HAD A YELLOW HIGHLIGHTED NOTE AND A PICTURE OF THE PURGE VALVE. THE O-RING IS RIGHT UNDER THE RIGHT FRONT LATCH. IT SAYS TO REMOVE THE SMALL BLACK O RING UNDER THE LATCH IF YOU CHECK IN FOR FLIGHT TO ALLOW THE EQUALIZATION OF PRESSURE, AND POP IT BACK IN AFTER THE FLIGHT TO ENSURE TO WATERTIGHT PROTECTION.

Thank you so much! On a black case, its easily overlooked.
