If the projector is particularly di rty, moisten the cloth with water 
containing a small amount of neutral de tergent, and then firmly wring the 
cloth dry before using it to wipe th e projector case. Then wipe the case 
again with a soft, dry cloth.
Use a commercially-available air blower, or use a lens cleaning paper to 
gently wipe the lens. If the air filters become clogged with dus
t, or if the message The projector

temperature. appears on the screen, clean the air filters and the air intake 
vent.
If the air filters become clogged with  dust, it can cause overheating and 
damage the projector.

Brightness Control    p.61
 If you continue to use the lamp after this period, the possibility of the  lamp breaking becomes greater.  When the lamp replacement 
message appears, replace the lamp with a new one as soon as 
possible, even if it is still working.

ceiling, you should always assume that the lamp is broken and be 
extremely careful when removing the lamp cover.
 Wait until the lamp has cooled down sufficiently before removing the  lamp cover. It takes a further one hour after the  cool-down
 period 
has finished for the lamp to be cool enough.
