Notice is given to the user to avoid the use of optical aids such as binoculars or telescopes inside the
beam.
When turning on the projector, make sure no one within projection range is looking at the lens.
Keep any items (magnifying glass etc.) out of the light path of the projector. The light path being
projected from the lens is extensive, therefore any kind of abnormal objects that can redirect light
coming out of the lens, can cause an unpredictable outcome such as a fire or injury to the eyes.
Any operation or adjustment not specifically instructed by the user's guide creates the risk of
hazardous laser radiation exposure.
Do not open or disassemble the projector as this may cause damage by the exposure of laser
radiation.
Do not stare into beam when the projector is on. The bright light may result in permanent eye damage.
Without following the control, adjustment or operation procedure may cause damage by the exposure of
laser radiation

Cleaning the Lens

Before cleaning the lens, be sure to turn off the projector and unplug the power cord to allow it to
completely cool down.
Use a compressed air tank to remove the dust.
Use a special cloth for cleaning lens and gently wipe the lens. Do not touch the lens with your fingers.
Do not use alkaline/acid detergents or volatile solvents such as alcohol for cleaning lens. If the lens is
damaged due to the cleaning process, it is not covered by the warranty.
Warning: Do not use a spray containing flammable gases to remove dust or dirt from the lens. This
may cause a fire due to excessive heat inside the projector.
