newbie

I was diagnosed with apnea some time ago, and just decided to try cpap. I was given a nearly unused DeVilbiss intellipap DV 55 D with no manual and after examining it and reading up on it have decided the company did not intend for the owner to set air pressure or delay or anything else on it. Is there a way around this, or do I need to moveon to another machine?
