I have determined that the instructions for operating the deflate function are wrong by careful experimentation on implant. I have run preliminary experiments on the lockout procedure and have not formed a firm conclusion yet, but indications are that the advice to give the inflation pump a squeeze to "lock" the valve is so much nonsense.
I leave the valve in the deflate position after deflating and do not have any problem at all with auto-inflation. If I follow the "squeeze the bulb after deflation to re-set the valve", I do get autoinflation. I plan to repeat the experiment, and if the results are consistent, I will report back.
I assumed this from day one. I have on numerous occasions, fallen asleep after pumping up and then waking up overnight realizing I was still inflated, so I press the deflate button and make an attempt to squeeze out the saline before falling asleep again.
What I have found though, is that upon waking up the next morning, I can continue to squeeze out saline from the cylinders *WITHOUT* pressing the deflate button again, and the check-valve in the pump squeals as the more saline is squeezed out.
The DEFLATE button activates a check-valve (on the AMS MS pump, at least). That's why the pump squeals as fluid is transferred back to the reservoir.
Does the valve "click" at the point where I have indicated by bold-facing and underlining your description?
