Hi. I have a Respironics REM-star System One Auto A-flex unit. The unit has the mask leak indicator set to the "on" position. There are multiple occasions when I am preparing for sleep, have the mask on, the mask is partially removed from my face, and yet, the mask leak indicator never beeps.
There is a silent mode on this unit, but if the mask leak indicator is on (which it is) I believe there is supposed to be some type of beep even if the unit is in silent mode.
I move around a lot during my sleep, so I think it would be helpful for the mask leak indicator to work. The unit is fairly new, I received it in January 2013.
Do you have any idea why the mask leak indicator is not working?
You have to enable a "alarm when leak" submenu as well, if it is the same model as I have. But it only gives the alarm when there is a significant sustained leak - you may not be getting that great a sustained leak - also it knows what is a leak and what is a full removal of the mask, etc. the alarm will only kick in if there is also some feedback from your breathing as well, since the auto stop is achieved by simply removing the mask altogether, and if the leak alarm system kicked in under those circumstances you'd never hear the end of it....
