Mask Type This setting allows you to select the appropriate Mask Type
resistance setting (also known as System One Resistance
Control) for your Philips Respironics mask. This feature allows
the device to adjust the level of pressure compensation to
match your mask. Refer to the packaging of your mask to
identify the resistance setting for your mask.
Note: It is important to use the appropriate "Mask Type"
resistance setting to ensure proper pressure delivery to the
patient.
Mask Type Lock This enables you to lock the Mask Type resistance setting if
you do not want the patient to change it.
Check Mask Fit You can enable or disable the check mask fit setting. This
feature allows the patient to check the fit of their mask prior to
starting therapy. This is done by measuring the amount of leak
in the patient circuit.
