TEMPERATURE WARNING INDICATOR
The TEMPERATURE WARNING Indicator flashes red when the internal temperature of the projector exceeds the normal temperature. The Indicator stops flashing when the temperature of the projector returns to normal. When the TEMPERATURE WARNING Indicator continues to flash, check the items listed below.
1 | The Ventilation slots of the projector may be blocked. In such an event, reposition the projector so that the ventilation |
slots are not obstructed. | |
2 | Air filters may be clogged with dust particles. Clean the air filters by following the section AIR FILTER CARE AND |
CLEANING below. | |
3 | If the TEMPERATURE WARNING Indicator remains on after performing the above checks, the Cooling Fans or the |
Internal Circuits may be malfunctioning. In that case, call Boxlight. |
AIR FILTER CARE AND CLEANING
The Removable Air Filters prevent dust from accumulating on the surface of the Projection Lens and the Projection Mirror. Should the Air Filters become clogged with dust particles, it will reduce the Cooling Fans' effectiveness and may result in internal heat build up and adversely affect the life of the projector.
Clean the Air Filters following the steps below:
1 | Turn the power off, and disconnect the AC power cord from the |
AC outlet. | |
2 | Turn the projector upside down and remove two Air Filters |
(Large and Small) by pulling the latches upward. | |
3 | Clean the Air Filters with brush or wash out the dust and |
particles. | |
4 | Replace each Air Filter properly. Make sure that the Air Filters |
are fully inserted. |
CAUTION
Do not operate the projector with the Air Filter removed. Dust may accumulate on the LCD Panel and the Mirror degrading picture quality.
Do not put small parts into the Air Intake Vents. It may result in malfunction of the projector.
The Air Filter is a small part. Ensure that children don’t eat or swallow it.
