Hey! I'm new! (Dances around in Christmas Tree gear.)
I'm doing some research into putting together my first kit. As part of that research I have visited several manufacturer's websites and downloaded manuals for various gear. When reviewing the manual for an AquaLung regulator I stumbled upon this fabulous phraseology:
There are two things I'm confused about in this particular nugget of information.
1.) It comes on the tail end of several pages discussing the use of exotic gases (specifically EANx up to 40% oxygen). Why would the manufacturer go to such lengths to discuss the capacity to use this regulator with exotic gas and then turn around to offer the above warning.
2.) Are there connections that aren't yoke or DIN? It is my (relatively inexperienced) impression that yoke and DIN are the only two regulator first stages available. If this is the case, how could one expect to use exotic gas with any regulator, given this warning?
Please enlighten me. I love to learn!
Thanks!

DANGER: If the regulator that you use is fitted with a yoke or DIN connection, it is designed for use only with compressed breathing air (21% oxygen and 79% nitrogen) which meets the EN 12021 standard. DO NOT USE this equipment with other mixtures or with gases containing more than 21% oxygen. Disregarding this rule could result in serious accident or death caused by fire or by an explosion.
