The software update is complete. To restart the projector, type in the “reboot” command and press Enter. The projector will now restart with the updated System Software.

3.12 Cleaning Lenses, ILA® Assemblies and Mirrors

The projection lens is the only item that will require periodic cleaning. The other assemblies are covered to prevent dust from entering or finger smudges. Cleaning may be needed due to special circumstances such as replacing the assembly or an adjacent assembly. Cleaning should only require removing excessive dust (use canned compressed air such as “Office Duster” or Aero Duster) or removing fingerprint smudges (use “Kodak Lens paper”, or equivalent) from the projection lens. As much as possible, clean the optics only when absolutely necessary.
