Only replace the projector lamp with the NEC VT75LPE lamp. These lamps are
available from NEC or SMART. Don't use any other lamps.
Never touch the rear of the interactive screen. If you do smudge this surface, lightly
spray alcohol-free glass cleaner onto a soft cloth and dab the affected area to
remove the marks. Never apply isopropyl alcohol, water or acetone, as these fluids
will damage the diffusion coating and permanently reduce the display quality.
After you shut down the projector, wait at least one minute before you unplug it.
Do not touch or replace the projector lamp (which will be very hot) for at least
an hour after turning off the projector.
