This is the only one I have and it is for the Pro which predates the Pro 2.

If that doesn't help check the link above that greatunclebill posted.
The combination for the cpap Pro2 and the BiPap Pro2 should work.
REMstar Pro 2 Setup
When in the Setup Menu, the humidifier ^ and ramp v buttons operate as up and down keys to change the settings, the left/right user buttons < > allow you to go to the previous/next question or setting, and the pressure start/stop button is used to exit the Setup Menu. Holding the humidifier or ramp buttons down will cause the values to change more quickly.
To enter the Therapy Setup Menu, hold the two top user buttons < > down while plugging in the power cord.
Continue holding the buttons down until the REMstar Pro 2 with C-Flex beeps twice.
Note: The word "setup" will appear on all of the screens indicating that you are in the Therapy Setup Menu.
If you press the Pressure start/stop button, you will exit the Setup Menu.
