OK, if I understand H2Olover and NiclasG correctly, I've got to have the transmitter pointed at my head. In other words, a straight line drawn from the center of the HP port through the center of the top of the transmitter cover should intersect the back of my head (and out through my nose ), right?
 First stage #> Transmitter O} Head
I have an Aqualung Mikron. I'm not sure there is any way to orient the first stage so that the transmitter points that way.
I think you got it right. You can orient coils
The transmitter is like a tube and the coil is on top of the battery pointing in the same direction as the transmitter.
The coil in the computer is oriented along the long side. When you lift you your hands before you straight forward the coils align.
