You will be prompted for acknowledgement.
WARNINGS
• The oxygen concentration delivered to the patient can be affected by
changes to the flow setting. Adjust the level of oxygen from the oxygen
source as necessary.
Check water The chamber has run out of water.
If using the HC360 reusable chamber: Remove the chamber and refill.
If using the MR290 auto-fill chamber: When a chamber runs dry, the chamber
float may be damaged. Replace the chamber and water bag.
To ensure continual humidification, always ensure that the water chamber
and/or water bag are not allowed to run out of water.

The most likely cause for this is that the unit is operating at a high flow rate in
low ambient conditions. Consider increasing ambient conditions to match the
recommended operating conditions or decreasing the target flow setting.
WARNINGS
• The oxygen concentration delivered to the patient can be affected by
changes to the flow setting. Adjust the level of oxygen from the oxygen
source as necessary.
[Power out] The unit has been disconnected from the mains/utility power socket.
No visual alarm. The auditory alarm will sound for 120 seconds. If power is

• A hazard can exist if different alarm presets are used on different units within any single area, eg. long term care facility
• Alarm limits set to extreme values can render the alarm system useless.
CHECKING ALARM SYSTEM FUNCTIONALITY
The functionality of the alarm system can be checked at any time when the unit is turned on.
Remove the heated breathing tube. You should see the "Check tube" visual alarm signal and hear the
auditory alarm signal. If either alarm signal is absent, do not use the unit. Contact your Fisher & Paykel
Healthcare representative.
