Works with Samsung UE46C7700!

After I returned the first glasses as allegedly defective, I had concerns, once again to order these glasses.
I have it but ordered again.
After more than 30 minutes to try in about 1 m distance without success and uncomfortable, I sat down in the normal viewing position at a distance of about 2.5 to 3 meters, turned the glasses again and lo and behold, it worked at once immediately. Why I can not say.
Perhaps the distance from the TV was just too low at the beginning, although it is in the instructions so. One must also not press the button 20 seconds, but only until the LED starts flashing, then that takes about 20 seconds.
When they stop and no synchronization carried out, just once about 3 -. 4 seconds until it flashes possibly repeated several times and maybe change the location.
After synchronization once done, you have to see 3D only briefly press the power button.
