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 A
UTOSET CS2 is starting up. If the alarm is functioning
correctly it will beep twice.
LOW MASK PRESSURE ALARM
TRIGGERED BY:
• pressure sensor line is blocked or disconnected
• air pressure at the mask has fallen below a set level
• mask is removed and SmartStop has been disabled.
IF A LOW PRESSURE ALARM SOUNDS:
1. Check that the air tube and sensor tube are connected properly.
2. Turn the A
UTOSET CS2 off and on again at the power switch. If the alarm persists,
return the unit to ResMed for servicing.
