how annoying!!! If it helps at all, the humidifier is optional. When you go into the settings, you can simply turn the humidifier off and skip that feature until you can find someone to help you. But make sure you do, in fact, turn it off, because if you don't, and you run PAP without water in the chamber, the bottom plate that warms it could burn. Here's some info on humidifier use that might be helpful.
