Key safety instructions

Design and testing of your projector have been carried out in compliance with the
latest safety standards for information technology (IT) devices. However, it is extremely
important for you to follow the instructions provided in this manual and product labels
during use to ensure user safety.
Safety Instructions
● Please read through this manual before using the projector. Save it for future
reference.
● Do not look straight at the projector lens during operation. The intense light
beam may damage your eyes.
● Refer servicing to qualified service personnel.
● Always open the lens shutter or remove the lens cap when the projector light
source has been switched on.
● In some areas there may be line voltage instability. This projector is designed to
operate safely within a mains voltage between 100 to 240 volts AC, but could fail if
power cuts or surges of ±10 volts occur. In areas where the mains voltage may
fluctuate or cut out, it is recommended that you connect your projector through
a power stabilizer, surge protector or uninterruptible power supply (UPS).
● Do not block the projection lens with any objects when the projector is under
operation as this could cause the objects to become heated and deformed or even
cause a fire.
● Do not place the projector on an unstable cart, stand, or cable. The product may fall
and sustain serious damages.
● Do not attempt to disassemble this projector. The projector contains high voltage
parts that may cause electrocution or death when it comes in contact with the human
body. Under no circumstances should you ever undo or remove any other covers.
Refer servicing to qualified service personnel.
● Do not place this projector in any of the following environments.
- Space that is poorly ventilated or confined. Allow at least 50 cm clearance from
walls and ensure free flow of air around the projector.
- Locations where temperatures may become excessively high, such as the inside of
a car with all windows rolled up.
- Locations that are too humid, dusty, or smoky may contaminate optical
components, shortening the projector's life span and darkening the image.
- Locations near fire alarms
- Locations where temperature exceed 35°C/95°F.
- Locations with altitudes greater than 3000 m (10000 feet).
