NOTE
To set the humidifier to non-heater wire mode, refer to the MR850
technical manual. (Rev. H or later).
If a heated breathing circuit is used while in non-heater wire mode
the humidifier automatically changes to heater wire mode. To use
non-heater wire mode again will require it to be manually set.
The airway probe out test does not work with non-heated breathing
circuits. A low humidity alarm will instead be given.
When there is no gas flow the humidifier will give a low humidity
alarm.
If the chamber runs dry either a water out alarm or a low humidity
alarm will occur.
