installed. When the update is complete, the system will

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.
