Luna 2, Need to adjust pressure. Can't find manual

I lost my cpap because of a fire in my apartment building. I received a very old resperonics machine and was able to change pressures easily. Worked great until it died..My niece sent me her Luna 2. I found a YouTube video , I was able to change from apap to cpap but I somehow went back to patient mode and can't get back in to change the pressure. She was at 6, I'm 17 so this is not going to work
I have an appointment with a sleep doctor September 20 , I'd like to get some decent sleep before then
The stress is bad enough, I have no idea when I can get back into my place and I've been living in a motel room. Have mercy on me, Cpap gurus..

Never mind, I figured it out on my own. The prospect of a decent night's sleep is a wonderful motivator.
