Buttons

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

1. Start/Stop Button ­

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

2. 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 one minute. Each time the button is pressed, the alarm silence period resets to one minute. See Chapter 6 for more information.

3. Up/Down Button

This button allows you to navigate the display menu and edit device settings.

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.
