Reset pressure on Resmed 7 help please!!!!

I have a Resmed 7 here I want to set up for travel and I need to reset the pressure. I have a set of instructions but they don't work I can get into ramping, altitude, etc. but cannot get into clinicians menu. Now I'm frustrated, can anybody give a guy a hand. I am traveling in the morning, Kansas city to Memphis to Tupelo and I will need my life support. If anybody knows and does not want to post puiblicly, how about sending me a private message. Thanks!!!!!
