SAFETY
Do not block the light coming out of the projector lens when in operation. The light will heat the object and
cause it to melt, burn or start a re.
Please do not open or disassemble the projector as this may cause electric shock.
See projector enclosure for safety related markings.
The unit should only be repaired by authorized service personnel.
Only use attachments/accessories specied by the manufacturer.
Do not look straight into the projector lens during operation. The bright light may harm your eyes.
This projector will detect the life of the light source itself.
Turn off and unplug the power plug from the AC outlet before cleaning the product.
Use a soft dry cloth with mild detergent to clean the display housing. Do not use abrasive cleaners, waxes
or solvents to clean the unit.
Disconnect the power plug from the AC outlet if the product will not be used for a long period of time.
Do not setup the projector in places where it might be subjected to vibration or shock.
Do not touch the lens with bare hands.
Remove battery/batteries from remote control before storage. If the battery/batteries are left in the remote
for long periods, they may leak.
Do not use or store the projector in places where smoke from oil or cigarettes may be present, as it can
adversely affect the quality of the projector performance.
Please follow the correct projector orientation installation as non standard installation may affect the projec-
tor performance.
Use a power strip and/or surge protector. As power outages and brown-outs can KILL devices.
Cleaning the Lens
Before cleaning the lens, be sure to turn off the projector and unplug the power cord to allow it to complete-
ly 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 ngers.
Do not use alkaline/acid detergents or volatile solvents such as alcohol for cleaning lens. If the lens is dam-
aged 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.
Warning: Do not clean the lens if the projector is warming up as this may cause the lens’ surface film to
peel off.
Warning: Do not wipe or tap the lens with a hard object.
To avoid electric shock, the unit and its peripherals must be properly grounded (earthed).
This equipment is equipped with a three-pin grounding-type power plug. Do not remove the grounding pin
on the power plug. This is a safety feature. If you are unable to insert the plug into the outlet, contact an
electrician. Do not defeat the purpose of the grounding plug.
