Device Alert Alarm—System Error
The Device Alert alarm is activated when the microprocessor detects a functional problem with
the ventilator. When this occurs, an alternate means of ventilation should be used. The ventilator
must be powered down by pressing the on/off button on the back of the unit.
If the cause of the device alert does not allow the ventilator to display the alarm message and the
device alert indicator to light, the ventilator will shut down, and the Shut Down Alert alarm will
activate.

WARNING:
If a device alert alarm occurs, immediately disconnect the patient from the ventilator and provide
an alternate method of ventilation until the cause of the alert has been determined and corrected.

in for service.
