pressure settings

I have been using a cpap for about 5 years now. my pressure setting is 17. my dad died last may and I got his goodknight 318 cpap. the problem is that it is set at 5. I took it over to apria health care and they could not figure out how to adjust the pressure. I need to know how to do this so I can use this as a spare if needed.

Puritan Bennett GoodKnight 420 Series
To get into the clinician's setup mode in a 420 series CPAP machine follow these steps:

1. make sure the CPAP machine is plugged in
2. find the secret button beneath the two "o"s in the word GoodKnight which appears just above the LCD screen
3. press the secret button and the Information Access button simultaneously for 2 or 3 seconds.

The CPAP machine will now be in the provider setup mode. Press the Information Access button to cycle through the list of adjustable settings, and use the arrow buttons to make adjustments. Below is a list of settings you can cycle through on a Puritan Bennett 420G:

* CPAP Pressure (only in provider setup mode)
* Ramp Time
* Ramp Start Pressure
* Hour Meter Value (which cannot be adjusted)
* Compliance Meter Value (which can only be reset to 0)
* Offset of Pressure Sensor (used for calibration purposes) (only in provider setup mode)
* Machine ID Number (which cannot be adjusted)

This machine is different than you describe. On the top left side is a pressure bar graff. Above that the ramp button, above that the power button. On back there is two dime size buttons with up/down arrows. There is a small square hole with three small switches. The only place this has Goodknight on it is on the warning label on the bottom.

'There is a small screw underneath a sticker on the back of the machine
You simply turn the screw one way to raise and the other way to lower the air'

I doubt that the original poster is still looking for this information after 7 years.
