About the Alice NightOne device icons
The top of the Alice NightOne device has 4 icons that light up to give you information.
•
Figure 1. The effort belt, nasal cannula, and pulse oximeter icons
The effort belt, nasal cannula, and pulse oximeter icons (see Figure 1) tell you
about the sensors.
o If these icons are green, it means the sensors are connected and working
properly.
o If one of these icons is flashing yellow, it means that sensor needs to be
connected or adjusted. It may take a few seconds for the icon to change
from yellow to green after you connect or adjust a sensor.

Figure 2. The good study indicator
The good study indicator (see Figure 2) can tell you how how much of the data
from your HST is good quality. It also tells you when the Alice NightOne device is
turning on or off. The 4 parts of the good study indicator can light up separately.
About the user button
The user button is the round button on the front of the Alice NightOne device. You don’t
need to use it during your HST if you don’t want to.
If you want, you can use the user button to:
• Make the sensors icons light up. You can do this during your HST to check if the
sensors are connected and working properly.
• End your HST and show the good study indicator. You can do this in the morning
to check how much good quality data was collected. For more information about
this, read the section “Checking the data quality” near the end of this resource.
