Friday night, after getting to Mehama, we eventually settled in to go to bed, and as usual, I set up my CPAP machine. Which refused to start. It made beeping noises and said "E-015" on the display. I tried various things, but nothing helped. The next day, examining the manufacturer's web site, I got nothing more than "call tech support." This morning, I called them and they said, "Take it back to the vendor who sold it to you; they'll have to service it." I called the vendor and left a message. At best, the earliest I could take it to them is next Monday. I hope the repair isn't too expensive, as I'm all out of HCSA money for this year. Meanwhile, I'm resigned to a week of less-good sleep -- and Lisa will have to put up with my snoring, which disturbs her sleep as well -- while I'm here.
