How to enter the Advanced Mode.

How to Enter the Advanced Mode:

To enter Advanced Mode, turn emWave on (page 12). Next, press and
hold the top of the Sensor Button for ten seconds. Your entrance into
Advanced Mode is confirmed by five distinctly fast beeps (low, low, low,
low, high). Now connect to emWave using the Ear Sensor or Thumb Sensor
Button and wait for pulse calibration to start an active session. After pulse calibration you will see the HRV Display.

Note: You can also enter the Advanced Mode from an active session in Basic
Mode the same way, by pressing and holding the top of the Sensor Button
for ten seconds. Entrance into Advanced Mode from an active session will be
indicated by the five fast beeps.

The Advanced Mode is used to display HRV and to go into the Stealth Mode.
Once you are in the Advanced Mode, Press the top button once (until it beeps once) to get into the HRV display. Press it once again (until it beeps once) to get into the Stealth Mode. Stealth Mode will make your emWave appear to be malfunctioning.
The only function available will be the Coherence indicator light at the top of the unit.
Press the top of the button once more (until it beeps once) to cycle back to the Breath Pacer mode.
