A:Answer We're sorry if we only have a Quick Start Guide available inside the box. The ONYX STUDIO 2's charging time is 5 hours. To turn it on while charging, just push the power button once. When the ONYX is charging with the power on, the power button will flash (1 sec interval), and would stop flashing when fully charged. Here are other LED indicators for the ONYX Studio 2:
For Power LED:
