Notes on AC Power Cord
ACPower Cordmustmeetrequirementof countrywhere youuse aprojector. Confirm
an AC plug type with graphics below and proper AC Power Cord must be used. If
supplied AC Power Cord does not match your AC outlet, contact your sales dealer.
This projector is equipped with a grounding type AC line plug. Make sure that your
outlet fits the plug. Do not defeat the safety purpose of this grounding type plug. We
highly recommend using a video source device also equipped with a grounding type
AC line plug to prevent from signal interference due to voltage fluctuation.
