I unlocked the machine by pressing two buttons and rebooting it and changed the ramping algorithm to less aggressive and increased the start pressure as it felt I was breathing from a straw when I tried to sleep. I use a nasal mask (not the pillows) since I am not a mouth breather - for me the Fisher & Paykel Eson 2 (L) was just the right fit - took about two different masks before I settled on it.
