I found these instructions online:MrKinnaman wrote:I have been battling my cpap for 3 years and recently found out that my pressure needs to be increased, however I have not found a manual to do so and have been waiting over 3 weeks for info on how to fix.
I have a SleepStyle 234, would anyone know where I can get the info?
- Turn on the HC234.
- Enter programming mode by holding down the "RAMP" (top) button and the "Next" (Right arrow/bottom button) for three seconds.
- The first screen will allow you to set adjust altitude, which is indicated by a drawing of a mountain range on the screen. You can change this to "m" for meters or "ft" for feet by pressing the Up or Down keys. Press the Right Arrow key to allow changing the altitude setting.
- Press the "NEXT" (Right arrow/bottom button) to advance to pressure setting which will be indicated by the characters "cm h20 " on the screen. Use the Up and Down keys to change the pressure setting.
- Lastly, push that bottom button again to exit programming mode.
I don't have this machine, so I can't answer any specific questions, but I hope these instructions help.
