Casio 3D Glasses YA-G30 User Manual page 10

When viewing images in a room illuminated by fluorescent lighting, the frequency of the lighting
can cause flickering of overall light in the room. If this causes problems, dim the fluorescent
lighting, change to a different type of lighting, etc. (Projection in a totally darkened room is not
recommended, especially when small children are present.)
Be sure to wear the 3D glasses correctly. The 3D image will not appear normal if the glasses
are worn upside down or backwards.
Do not look at another type of monitor (computer monitor, digital timepiece, calculator, TV,
etc.) while wearing the 3D glasses. Take off the 3D glasses before viewing any other device
besides a CASIO 3D projector.
