THE ALARMS

The AUTOSET CS2 unit is fitted with alarms to alert you to changes that will affect your treatment. The most common reason for an alarm to sound is because the system has not been properly assembled. Check that the air tubing and pressure sensor tube have been properly attached to the flow generator and mask (and humidifier if used).

You can mute an alarm by pressing the Alarm Mute key once. Unless the alarm requires you to turn the power off, you can press any key again to remove the alarm message from the LCD screen. If the problem is still present, the alarm will sound and display again after one minute. The Alarm LED will remain lit for as long as the problem is present.

All menus remain available during an alarm.

We recommend that you test the audible alarm once a week. To do this, hold down the Mute key while the AUTOSET CS2 is starting up. If the alarm is functioning correctly it will beep twice.
