Important safety instructions
Your projector is designed and tested to meet the latest standards for safety of information
technology equipment. However, to ensure safe use of this product, it is important that you
follow the instructions mentioned in this manual and marked on the product.
Safety Instructions
1.
Please read this manual before you operate your projector.
Save it for future
reference.
2.
Do not look straight at the projector lens during operation.
The intense light beam
may damage your eyes.
3.
Refer servicing to qualified service personnel.
4.
Always open the lens shutter or remove the lens cap when the projector lamp is
on.
5.
In some countries, the line voltage is NOT stable. 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).
6.
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. To temporarily turn off the lamp, press BLANK on the projector or
remote control.
7.
The lamp becomes extremely hot during operation. Allow the projector to cool for
approximately 45 minutes prior to removing the lamp assembly for replacement.
8.
Do not operate lamps beyond the rated lamp life. Excessive operation of lamps
beyond the rated life could cause them to break on rare occasions.
9.
Never replace the lamp assembly or any electronic components unless the projector is
unplugged.
10. Do not place this product on an unstable cart, stand, or table. The product may fall,
sustaining serious damage.
11.
Do not attempt to disassemble this projector. There are dangerous high voltages inside
which may cause death if you should come into contact with live parts. The only user
serviceable part is the lamp which has its own removable cover.
Under no circumstances should you ever undo or remove any other covers. Refer
servicing only to suitably qualified professional service personnel.
12. 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 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 where excessive humidity, dust, or cigarette smoke may contaminate optical
components, shortening the projector's life span and darkening the picture.
- Locations near fire alarms
- Locations with an ambient temperature above 40°C / 104°F
- Locations where the altitudes are higher than 3000 m (10000 feet).
