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 in a circular 
motion.

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. Replace the lamp when the 
brightness is no longer acceptable. You can order new lamp mod-
ules from Boxlight. See “Accessories” on page 38 for information.
Follow these steps to replace the projection lamp:
1
Turn off the projector by unplugging the power cord. 
2
Wait 30 minutes to allow the projector to cool thoroughly.
3
Invert the projector on a soft flat surface, then insert a small 
screwdriver or other flat object into the tab on the lamp mod-
ule door (Figure 20).
4
Pull the lamp door up and remove it.
