treatment screen will give you the option to start warming up the humidifier prior to

Starting your treatment
1Turn the humidity control dial to three ( ). You can adjust the control dial up or down
at any time to find the setting that is most comfortable for you. The setting
switches heated humidification off and delivers minimum humidification while a
setting of six ( ) delivers maximum humidification.
Note: The ResMed Tubing Wrap is designed to enhance comfort by maximising
heat retention along the air tube.
2Start treatment as described in your device user guide.
Note: The H4i is thermostatically controlled to maintain a constant temperature. The
indicator light will brighten to indicate when the device is actively heating and dim
when it has reached its set temperature.
3Lie down and arrange the tubing so that it moves freely when you turn in your sleep.
