Below are a bunch of useful questions and answers:
Poly requires a charger that supports 2A or more. See Amazon for example chargers that support 2.4amps. Make sure you also have a decent USB Charging cable.
While charging, both the Poly and Mojo lights will light up white.
On firmware 1.06 both lights will turn off when charging is complete.
While charging, Poly is actually online and checking for updates.
It takes about 4 hours for both Poly and Mojo to charge fully for a total of 8 hours.
Pushing the configuration tool into the config hole for a second will have Poly play out the headphone port what mode it's in as well as its IP Address.
Holding the button in for a total of about 8 seconds will have Poly change modes and tell you what mode it's moving to.
