Notes on the AC Power Cord

Please confirm your AC plug type with the graphics below and ensure that the proper
AC Power Cord is used. If the supplied AC Power Cord does not match your AC outlet,
please contact your sales dealer. This projector is equipped with a grounding type AC

of this grounding type plug. We highly recommend using a video source device also
equipped with a grounding type AC line plug to prevent signal interference due to
voltage fluctuations.
