electrical parts'life will be shortened .
●There are safety cord holes at the bottom of the base of a projector. In view of safety, please run the safety cord
supplied through the safety cord holes for safety support.
●Before any installation, maintenance and cleaning work, please ensure a projector is disconnected from power
mains.
● While running normally under normal ambient temperature, the temperature of the external surface of the
metal housing of a projector including that of the heat sink may reach
●While the lamp is stricken for the first time, there will be smoke and strange smell. It's normal and does not
mean a projector has some defects.
●While it running, don't touch the metal housing to avoid being burned!
●Do not mount a projector directly on inflammable surface.
●Do not project the beam straightly on combustible items and the minimum distance between a projector
and illuminated items is 18m.
●A projector should be installed with good ventilation and the minimum distance between a projector and a wall
is 50cm.At the same time, please ensure the fans and air inlets and outlets are workable.

INSTRUCTIONS
●CLEANINGAND MAINTENANCE
Under normal running, the protective units of a projector should be inspected regularly like power fuse. If it is burned, please
install a new one and ensure it is the same rating as the burned one. For a projector with an over-temperature protective unit,
please inspect cooling units regularly like cooling fans, heat sink and other cooling parts. Please check if the fans run normally or
fans and air inlets are blocked by dust. To keep air inlets /outlets clean, cooling fans should be cleaned every 15days.
For projectors with lens, reflectors and coated filters, the accumulation of oil, smoke and dust on them will compromise the light
output. Cleaning a projector is very necessary to ensure a reliable use. Internal and external lens, flat glass, reflector and coated
filters need to be cleaned periodically to optimize light output.
Cleaning frequency is to be decided by operations and its environment. Use soft cloth and normal detergent for glass for cleaning
work. It's advised external optical system be cleaned every 20days and internal optical systems every 30/60days. For a projector
with high IP rating, if no damage inside, it is advised to clean the surfaces of its housing in principle. Keep lens clean and do not
touch optical parts with bare hands.
SPECIALNOTE:
It's normal phenomena that there will be mild water mist on the lens while the waterproof product is in use.
●Before any maintenance and cleaning, please ensure a project is off the power.
●Only a qualified person is allowed to do maintenance.
75 ℃ at maximum.
