As you practice increasing your coherence and reducing your stress
levels, your HRV range may start to increase. As your HRV range
increases, you'll see fewer lights at the top and bottom on the Heart
Action Strip. In simple terms, the fewer lights, the wider the range of
your HRV. The more lights that display on the Heart Action Strip, the
narrower the range of your HRV. For more information on HRV go to:

Cycling through Advanced Mode Displays
During an active session in Advanced Mode, you can cycle through
three display options: HRV Display, Breath Pacer Display and
Stealth Display. To cycle to each display, you must perform a medium
press (two seconds) on the top of the Sensor Button. Changing into a
different display is indicated by one distinct tone.
Breath Pacer Display
The Breath Pacer is the same as when you are in the Basic Mode.
Watch your Coherence Score fill up the Heart Action Strip.
