This projector uses a high-pressure lamp which must be handled carefully and properly.  Improper
handling may result in accidents, injury, or create a fire hazard.
Lamp lifetime may differ from lamp to lamp and according to the environment of use.  There is no
guarantee of the same lifetime for each lamp.  Some lamps may fail or terminate their lifetime in a
shorter period of time than other similar lamps.
If the projector indicates that the lamp should be replaced, i.e., if the LAMP REPLACE INDICATOR
lights up, replace the lamp with a new one IMMEDIATELY after the projector has cooled down.  
( Follow carefully the instructions in the LAMP REPLACEMENT section of this manual.  )  Continuous
use of the lamp with the LAMP REPLACE INDICATOR lighted may increase the risk of lamp explosion.  
A Lamp may explode as a result of vibration, shock or degradation as a result of hours of use as its
lifetime draws to an end.  Risk of explosion may differ according to the environment or conditions in
which the projector and lamp are being used.
IF A LAMP EXPLODES, THE FOLLOWING SAFETY PRECAUTIONS SHOULD BE TAKEN.
If a lamp explodes, disconnect the projector’s AC plug from the AC outlet immediately.  Contact an
authorized service station for a checkup of the unit and replacement of the lamp.  Additionally, check
carefully to ensure that there are no broken shards or pieces of glass around the projector or coming out
from the cooling air circulation holes.  Any broken shards found should be cleaned up carefully.  No one
should check the inside of the projector except those who are authorized trained technicians and who are
familiar with projector service.  Inappropriate attempts to service the unit by anyone, especially those who
are not appropriately trained to do so, may result in an accident or injury caused by pieces of broken
glass.

Removable Air Filter prevents dust from accumulating on the surface of Projection Lens and Projection  Mirror.  Should 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 Air Filter following the steps below: 
Clean Air Filter with a brush or wash out dust and particles.3
Replace Air Filter properly. Make sure that Air Filter is fully
inserted.4
CAUTION
Do not operate the projector with Air Filter removed.  Dust

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.
