Problem / possible cause
No display
Power failure. The device stops delivering
air pressure.
Power not connected or device is not
switched on.
Treatment pressure seems low
Ramp time is in use.
Air filter is dirty.
Air tubing is kinked or punctured.
Air tubing is not connected properly.
Mask and headgear not positioned
correctly.
Plug(s) missing from access port(s) on
mask.
Pressure required for treatment may have
changed.
There is a large impedance (eg,
bacterial/viral filter) in the air circuit.
Humidifier control dial set too high,
resulting in accumulation of water in the
air tubing.
Treatment pressure seems high
Pressure required for treatment may have
changed.
There is a change in the impedance in the
circuit configuration.
The device does not start when you breathe into the mask
SmartStart/Stop not on.
Breath is not deep enough to trigger
SmartStart.
There is excessive leak.

Solution
•
Remove the mask or the catheter mount from the
tracheostomy tube until power is restored.
•
Check the power cable connection between the mains
power or external battery and the device.
•
As the internal battery ages, the available capacity
decreases. When the remaining battery capacity is low, it
can affect the battery charge level indication and lead to
power failure without activating Low or Empty battery
alarms. ResMed recommends the battery be tested after
two years to assess the remaining battery life (refer to
Internal battery (see page 3)).
Ensure the power cord is connected and press the switch at
the back of the device once.
Wait for air pressure to build up.
Replace air filter.
Straighten or replace tubing.
Connect the air tubing firmly at both ends.
Adjust position of mask and headgear.
Replace plug(s).
See your clinician to adjust the pressure.
Perfom the Learn Circuit function.
Turn humidifier control down and empty the water from the air
tubing.
Consult your clinician.
Perform the Learn Circuit function.
Consult your clinician.
Take a deep breath in and out through the mask.
Adjust position of mask and headgear.
Replace plug(s).
Connect firmly at both ends.
Straighten or replace tubing.
Perform the Learn Circuit function.
