Working with alarms

The S9 VPAP Tx is fitted with an alarm module that continuously monitors both therapy and device conditions. Alarms are only activated when therapy is running. An alarm condition can be indicated by an audible sound, a flashing yellow LED or a message on the screen.

Note: The alarms should be tested after final system setup to ensure the alarms work as required.
