A thoughtful Apnea Board member (Greggers In Toronto) posted the following instructions for entering the Setup Menu of the Philips-Respironics REMstar SE CPAP machine [pictured above]:
Remove the adapter power cord from the back of the machine, wait a couple of seconds, then plug it back in. The unit should power up.
Press the power on button, let the unit blow for a couple seconds, then press the power button again. The blower will shut off.
Press the farthermost button on the left (the Ramp button) and the left-arrow button right beside it, simultaneously, and hold them both down (around 5 seconds) until P-1 shows up on the display. This will indicate you are in the Setup Mode.
At this point, you will be allowed to cycle through the setup menu. As you depress either the left or right arrow key, you will land on several icons on the display that indicate which setting you can adjust. You want to get to the cm H2O icon. Depress either left or right until you reach that icon.
Press the power button once, and your pressure setting will blink. You may then use the left or right buttons to change your pressure setting.
When you are done, simply press Ramp and the left-arrow button simultaneously, and hold until P-0 flashes briefly. You are then back in the standard operating mode.
Please note that the left and right arrow keys may stick. You must be SURE you are pressing the left-arrow key independently. I found this was easiest to achieve by using my index finger to depress the Ramp button, and my pointer finger to depress the leftmost edge of the left-arrow button.
I hope this helps others.
