MAINTENANCE

WARNING TEMP. INDICATOR

WARNING TEMP. Indicator flashes red when an internal temperature of a projector exceeds the normal temperature. This Indicator stops flashing when the temperature of a projector returns to normal.

When WARNING TEMP. Indicator continues to flash, check the items listed below.

1

Ventilation Slots of the projector may be blocked. In such an event, reposition the projector so that Ventilation Slots

are not obstructed.

2

Air Filters may be clogged with dust particles. Clean Air Filters by following the section AIR FILTER CARE AND

CLEANING below.

3

If WARNING TEMP. Indicator remains on after performing the above checks, Cooling Fans or the Internal Circuits may

be malfunctioning. In that case, call Boxlight.

AIR FILTER CARE AND CLEANING

Removable Air Filters prevent dust from accumulating on the surface of Projection Lens and Projection Mirror. Should Air Filters 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 Air Filters 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 two Air Filters

 

(Large and Small) by pulling the latches upward.

3

Clean Air Filters with a brush or wash out dust and particles.

4

Replace each Air Filter properly. Make sure that Air Filters are

 

fully inserted.

CAUTION

Do not operate the projector with Air Filter removed. Dust may accumulate on LCD Panel and Projection Mirror degrading picture quality.

Do not put small parts into Air Intake Vents. It may result in malfunction of the projector.

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 1-800-762-5757 or 360-779-7901 for cleaning.

CLEANING PROJECTION LENS

Follow these steps to clean Projection Lens:

1

Apply a non-abrasive camera lens cleaner to a soft, dry cleaning cloth. Avoid using an excessive amount of cleaner.

 

Abrasive cleaners, solvents or other harsh chemicals might scratch a surface.

2

3

Lightly wipe a cleaning cloth over Projection Lens.

When the projector is not in use, replace Lens Cover.
