How long does it take to fully charge the Xstream, and what does the LED indicate during charging?
A full charge takes approximately 3 hours. During charging, the LED (A11) flashes green, and changes to solid green when the battery is fully charged. You should disconnect the charger cable once the headset is fully charged. (Page 6)
