button. Once cancelled the power fail alarm will not re-activate.
Low Internal Battery

operate when the battery is almost depleted
The user cannot replace this battery. Refer to qualified technical personnel for battery
replacement.
Low External Battery
When running on an external battery, the alarm will operate
when the battery is almost depleted. Machines fitted with an internal battery will
automatically switch to internal battery power without alarming.

A pre-set low pressure alarm is provided. If the control pressure falls
to below 50% of the set IPAP level for 10 seconds an audible and visual alarm will
operate.
High Pressure
A pre-set high-pressure alarm is provided. If the pressure rises above
120% of the working pressure, an audible and visual alarm will operate after a 2
second delay.
Breathing Circuit Disconnect
A disconnect alarm is provided. This is
activated by analysis of the inspiratory and expiratory flow waveform. An audible
and visual alarm will operate.
Fault
The alarm may also be operated by an internal fault. In this case the fault will
be displayed on screen.
These alarms may be muted for approximately 2 minutes to allow for setting up of
the ventilator.
Low Alarm Battery

indicates a depleted mains fail alarm battery. If the ventilator has been stored for more
than a few weeks the internal battery will self discharge. In this case the alarm will stop
after the battery has recharged.
The user cannot replace this battery. Refer to qualified technical personnel if the alarm
operates when the ventilator is in daily use.
