WARNING TEMP. INDICATOR
The WARNING TEMP. indicator flashes red when an internal temperature of the projector exceeds the normal temperature. The projector cannot be turned on while the WARNING TEMP. indicator is flashing with the READY indicator off. When the temperature inside the projector returns to normal, the READY indicator lights green. Then you can turn the projector back on. The WARNING TEMP indicator stops flashing after turning the projector on. If the WARNING TEMP indicator continues to flash after turning the projector back on, check the items listed below.

AIR FILTER CARE AND CLEANING
Removable Air Filter prevents dust from accumulating on the surface of the Projection Lens and Projection Mirror. Should the Air Filter become clogged with dust particles, it will reduce Cooling Fans’ effectiveness and may result in internal heat build up and adversely affect the life of the projector. Clean the Air Filter following the steps below:
1 | Turn off the projector, and disconnect AC power cord from the |
AC outlet. | |
2 | Turn the projector upside down and remove the Air Filter by |
pulling the latches upward. | |
3 | Clean the Air Filter with a brush or wash out dust and particles. |
4 | Replace the Air Filter properly. Make sure that the Air Filter is |
fully inserted. |
CAUTION
Do not operate the projector with the Air Filter removed. Dust may accumulate on the LCD Panel and the Projection Mirror degrading picture quality.
Do not put small parts into the Air Intake Vents. It may result in malfunction of the projector.

Pull up and remove.
RECOMMENDATION
We recommend avoiding dusty/smoky environments when operating a projector. Usage in these environments may cause poor image quality.
When using under dusty or smoky conditions, dust may accumulate on a lens, liquid crystal panels, or optical elements inside the projector. This condition may degrade the quality of a projected image.
When the above symptoms are noticed, contact Boxlight at
