The manual is not available in English but I summarize here once the key points to:
Power-Button 3 sec. press - goggles on and active (the blue LED starts blinking and the to establish a connection with the 3D TV on)
Power button for 5 seconds. press - glasses are made
There is a second button on the glasses but I know not for what is this ...
The charge of the spectacle takes place via the included USB cable that can be angschlossen to the PC, TV or laptop. Flashing red glasses, she is in the boot state. If the LED is solid red, the glasses are fully charged.
According to the description is the battery life sufficient for about 50 hours..
