Do not touch the rear surface of the screen or apply isopropyl alcohol, water or
acetone to it. These fluids will damage the diffusion coating, resulting in a
permanent deterioration in display quality.
After you turn off the projector, allow at least one minute to elapse before you
disconnect the 4000i's power cord from the power outlet. Don't touch or
replace the projector lamp (which will be very hot) for at least an hour.
