Cleaning the Lens
Follow these steps to clean the projection lens:

•
Avoid using an excessive amount of cleaner.
•
Abrasive cleaners, solvents or other harsh chemicals might
scratch the lens.
2 Lightly wipe the cleaning cloth over the lens.
3 If you don’t intend to use the projector immediately, replace the lens
cap.
Replacing the Projection Lamp
WARNING: To avoid burns,
allow the projector to cool for at
least 30 minutes before you
open the lamp module door.
Never extract the lamp module
while the lamp is operating.
The lamp hour counter in the Status menu counts the number of hours
the lamp has been in use. The projectors use a metal halide bulb. These
types of bulbs deteriorate over time. Replace the lamp when the bright-
ness is no longer acceptable. You can order new lamp modules from
your TOSHIBA dealer. See “Accessories” on page 45 for information.
Follow these steps to replace the projection lamp:
1 Turn off the projector and unplug the power cord.
2 Wait 30 minutes to allow it to cool thoroughly.
3 Place the projector on its side, then insert a small screwdriver or
other flat object into the tabs on the lamp module door (Figure 24).
4 Pull the lamp door up and remove it.
