What does the Green light at the Bottom mean?Jun 07, 2018
When you plug in the emWave2 device to the USB cable, a Green light comes on in the lower left corner.
This indicates that power is now being applied to the device to charge the unit. Shortly afterwards the Blue lights in the Heart Action Strip will begin to cycle up and down. When the device is fully charged there will be 5 solid Blue lights. At that time the device can be unplugged and it's ready for mobile function.
