The projector is equipped with a three wire plug having a third (grounding) prong. This is a
safety feature. If you are unable to insert the plug into the outlet, contact an electrician to have
the outlet replaced. Do not defeat the safety purpose of the grounding-type plug.
Ventilation!
Before unplugging the power cord, make sure the internal lamp cooling fans have shut off. The
fans automatically shut off when the projector has adequately cooled down.
