What do the different light colors mean on my E4L hand scanner?

The colors on the scanner indicate the following:

Red flashing - your hand scanner is charging

Red solid - your hand scanner is fully charged

Green (when not plugged into a computer) - ready to pair (via Bluetooth low energy) directly in the NES Health app not via the phone's Bluetooth settings (only available for clients of BWS practitioners)

Blue (when not plugged in) - paired/connected to the NES Health app and ready to be used for scanning
