Maintenance and Troubleshooting

Cleaning the Interactive Whiteboard and other Components

Clean the interactive whiteboard surface regularly. Otherwise, dust may build up, diminishing the
performance of the 2000i.
Do not spray glass cleaner directly onto the screen surface. Instead, spray the cleaner lightly on a
cloth and then gently wipe the screen surface. The 2000i uses digital cameras located inside the
frame. If you allow excess glass cleaner to flow into the crack between the frame and the writing
surface, the fluid could damage the cameras.
Before you clean the interactive whiteboard, log off the computer. If you touch the screen when the
computer is in any other state (e.g., with a program open or at the desktop), you may activate
program components or scramble desktop icons. After you log off, put the projector into standby
mode so you can easily see dirt and streaks.
Remove marks made with a permanent marker by completely covering them with the ink from a
dry-erase marker (not a low-odor marker). Then wipe with a soft cloth. Dry-erase ink contains
solvents that work to remove permanent ink. If any trace of the original permanent ink remains,
spray standard glass or whiteboard cleaner lightly on a cloth and then gently wipe the screen.
The back of the interactive whiteboard screen is well protected from handling by its location on the
inside of the unit. However, if it must be dusted, or if a mark has been made on its surface, dab it
gently with a soft cloth that's sprayed with standard, alcohol-free glass cleaner. Do not apply the
cleaner directly to the surface.
Periodically dust the mirrors and unit components using a soft cloth. To clean the mirrors, use a
standard, alcohol-free glass cleaner.
CAUTION
Do not, under any circumstances, apply isopropyl alcohol, water or acetone to the
rear surface of the interactive screen. Any of these fluids could damage the
diffusion coating, resulting in a permanent deterioration in display quality.

Cleaning the Projector

Unplug the projector before you clean it.
Periodically clean the projector casing with a damp cloth. If it is heavily soiled, you can use a mild
detergent. 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.
Cleaning the Filter and Clearing the Filter-Cleaning Message
Clean the air-filter sponge with a vacuum after every 100 hours of operation (more often in dusty
conditions), as described on page 51 of the NEC VT470/570/670 User's Manual.
A "Please Clean Filter" message from the projector will appear on the bottom of the screen after
every 100 hours of operation. However, this message doesn't disappear automatically after you've
cleaned the filter. You must use the projector remote control to clear the filter usage meter, as
follows:
