Important Information iii
WARNING: Do not, under any circumstances, apply isopropyl alcohol, water or acetone to the
rear surface of the interactive whiteboard screen. If any of these fluids come into contact with this
surface, the diffusion coating could be damaged, resulting in a permanent deterioration in display
quality.
Cleaning the Projector
Before you clean the projector, make sure it's been unplugged.
CAUTION: Don't unplug the power cable while the hourglass icon or the message "Please Wait a
Moment" appears on the screen, or while the POWER or STATUS indicators are alternately
flashing.
Periodically clean the projector with a damp cloth. If it has become heavily soiled you may use a
mild detergent, but don't use strong detergent or a solvent, such as alcohol or thinner. Use a
blower or lens paper to clean the lens, being careful not to scratch or mar the lens.
Clean the air-filter sponge with a vacuum after every 100 hours of operation (more often in dusty
conditions) as described on page E-54 of the NEC MT1065/MT1060 User's Manual. To access
the air-filter sponge, face the front of the cabinet, open the front doors, and loosen the front
projector strap.
Replacing the Projector Lamp and Filter
Replace the lamp when you see the message "The lamp has reached the end of its usable life.
Please replace the lamp." To do this, order a replacement standard lamp (MT60LP) or extended
life lamp (MT60LPS) from your NEC or SMART dealer.
In order to replace the lamp, you must first remove the projector from the cabinet. See page 40
of this manual and page E-53 in the NEC MT1065/1060 User's Manual for instructions on
replacing the lamp.
You should replace your projector lamp after 2000 hours (normal mode). The projector will turn off
automatically and go into standby mode after 2100 hours (normal mode). To find out how many
hours of lamp use remain, go to the projector menu and select Help > Information > Page 4 tab.
Replacing the used lamp with a new lamp automatically clears the lamp usage hours. When you
replace the projector lamp, you should also replace the projector filter. This filter is automatically
shipped with the replacement lamp.
CAUTIONS
• Do not remove any screws except the two lamp case screws. You could receive an electric
shock.
• Do not replace the projector lamp with any lamp but the NEC MT60LP standard lamp or the
NEC MT60LPS extended life lamp available from NEC or SMART.
• After you turn off the projector, allow at least one minute to elapse before you unplug it. Do
not touch or replace the projector lamp (which will be very hot) for at least an hour.
