I just got my N2 today and I'm excited!
But there's some confusement:
I was trying to charge it after registering and testing out. First I connected it to the PC usb port, the LED became purple.
I then tried it with my android phone charger, and the light turned red. Does that mean it's being charged? I cannot find any info in the manual guide....
And how do I know when it's fully charged?
