Maintaining the 4000i
Use this section of the manual to learn how to:
• clean the interactive whiteboard and other components (this page)
• clean the projector (page 28)
• replace the projector’s lamp (page 28)
• restore the projector’s settings (page 29)
• calibrate the cameras (page 29)
Cleaning the Screen and Other Components
Before you clean the interactive whiteboard, turn off the computer. If you touch the screen when
the computer is in any other state, you may activate program components or scramble desktop
icons. Switch the projector to Standby mode so you can see dirt and streaks on the screen.
Clean the screen’s external surface regularly so that dust buildup doesn’t disrupt the 4000i’s
operation. Don’t spray glass cleaner directly onto the screen surface. Instead, spray the cleaner
lightly on a soft cloth and then gently wipe the screen surface.
If there is permanent marker ink on the screen, you can remove it by completely covering it with
the ink from a high-odor dry-erase marker (not a low-odor marker), and then wiping the screen
with a soft cloth. If any trace of the original permanent ink remains, spray a soft cloth with standard,
alcohol-free glass or whiteboard cleaner, and gently wipe clean.
The back of the interactive whiteboard screen is well protected from handling because it’s located
inside the 4000i cabinet. However, if you must clean the rear of the interactive screen, dab it gently
with a soft cloth that’s been sprayed with standard, alcohol-free glass cleaner. Don’t apply the
cleaner directly to the rear surface.
The 4000i’s cameras are well protected from dust and dirt, so you should only have to clean the
lenses occasionally. When you do so, don’t spray glass cleaner directly onto the lens. Instead,
spray the cleaner on a cotton-tipped swab and gently rub it on the lens. If excess glass cleaner
flows into the crack between the frame and the screen, the fluid could damage the cameras.
Periodically dust the mirrors and unit components of the 4000i 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. These fluids damage the diffusion coating,
resulting in permanent deterioration of display quality.
