Buttons
The following buttons are included on the front panel of the device.

This button turns the airflow on or off, starting or stopping
therapy.

Alarm Indicator and Audio Pause Button
This button serves two purposes: it temporarily silences
the audible portion of an alarm, and it also acts as an alarm
indicator. When silencing an alarm, if the cause of the alarm is
not corrected, the alarm sounds again after two minutes. Each
time the button is pressed, the alarm silence period resets to two
minutes. See Chapter 6 for more information.

Front Panel Controls and
Display Screen
Note:
When you start therapy,
the display backlight and the
backlights on the buttons turn
on, the red and yellow alarm
LEDs turn on momentarily, and
an audible indicator sounds
to indicate that therapy has
started. The Startup screen
appears on the display.
WARNING
To make sure the device is operating
properly at start-up, always verify
that the audible tone sounds and
the alarm LEDs light red and then
yellow momentarily. Contact Philips
Respironics or an authorized service
center for service if these indications
do not occur at start-up.
