Starting the device
1. Ensure power is supplied to the device. The first screen to display will be the Philips
logo, Respironics logo, followed by the device model screen, and then a screen that
contains a summary of your therapy. See the “Therapy off display” section later in this
manual for a description of the User Interface (UI) screens.
Note: The device may prompt you to set the language and time. These settings
can always be adjusted from the device settings screen.
2. Put on your mask assembly. Refer to the instructions supplied with the mask.
A small amount of mask leak is normal and acceptable. Correct large amount of mask
leaks or eye irritation by adjusting your mask headgear.
Note: If you are using the device in a bed with a headboard, try placing the
tubing over the headboard. This may reduce tension on the mask.
3. Press the Therapy button on top of the device to turn on airflow and begin therapy. The
Therapy button ring will illuminate blue.
Note: If your home care provider has enabled the Automatic On feature, the
device will automatically turn the airflow on when you put on your mask.
4. Press the Therapy button again to turn off the therapy. The Therapy button ring will
illuminate white.
Note: If your home care provider has enabled the Automatic Off feature, the
device will automatically turn the airflow off when you take off your mask.
