It says my machine wasn't used last night, but I know I used it.

Check that:

  • Your CPAP machine is turned on and plugged into power.
  • You have a good wireless signal on your machine.
    The more bars you see on the wireless signal icon on your machine, the better the signal strength. If you do not see many bars, try moving the machine to a better location.
  • Your machine is not set to airplane mode.
    For more information about turning off airplane mode, see your machine's user guide.
  • The serial and device numbers in myAir match what is on the back of your machine.
