2Lightly wipe the cleaning cloth over the lens.

Replacing the Projection Lamp

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 brightness is no longer acceptable. You can order new lamp modules from Boxlight. See “Accessories” on page 45 for information.

Follow these steps to replace the projection lamp:

1Turn off the projector and unplug the power cord.

2Wait 30 minutes to allow it to cool thoroughly.

3Place the projector on its side, then insert a small screwdriver or other flat object into the tabs on the lamp module door (Fig- ure 24).

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.
