  Charging the 3D Glasses

  When the status light on the glasses flashes red to indicate a low battery, it is time to charge the glasses.
  1. Connect the smaller end of the charging cable to the port on the bridge of the glasses.
     
     

     Note: Make sure you connect the cable in the correct orientation or you may damage the glasses or cable.

  2. Do one of the following:
     • Plug the other end of the charging cable into a powered USB port on a computer or other device.
     • Plug the other end of the charging cable into a USB-to-AC adapter with the following specifications:

       Input: 100-240V, ~0.15A, 50-60Hz

       Output: 5V=1A

  The glasses are fully charged when the status light on the glasses stays green.
