I bought a used PR System One REMstar Auto because I want ed to take it camping with a battery. I tried to reset the pressure to my usual 8 cm/H2O. It seemed to work but the auto-on initiation caused by inhalation was uncomfortable. I felt like I was on a respirator. I tried to adjust it and the programming went nuts on me and shut down - beeping. Now, it turns on - immediately turns off, beeps and says "Contact Service." Local CPAP dealer won't work with me because I don't have an MD Rx and they're afraid of the liability.
All I want the machine to do is blow a steady, flat 8 cm/H2O pressure - no ramp up, no auto-on, no programming - nothing else, like my ancient ResMed Sullivan V.
Can anyone help me.
