Other troubleshooting
Problem / possible cause
Solution
No display
Power failure. The device stops delivering
air pressure.
•
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 2)).
