Plugging the Projector In
Connect the power cord to the projector and plug it in.
Connect the ground terminal on the power plug to ground. Not doing so
could result in an electric shock. Additionally, it may cause computers to
be affected by electromagnetic interference and impair TV and radio
reception.
• Fully insert the power cord plug into the socket.
• After turning off the projector, wait at least 5 minutes before turning it on again. It may
shorten the lamp life if you turn on the projector immediately after turning it off.
Unplug the power cord when the projector is not in use.
