Anyway, our CPAP machines have a clock inside. Some machines allow the user to reset the clock to adjust to time changes. Some do not.
We made a wiki page detailing how to change the time on the machines that allow it.
We only have the instructions for the Icon and ResMed's S9. Respironics does not allow the user to change the time. If you have another machine AND know how to set the clock, please let us know. Contact email address is near the bottom of the page linked above.
