Safety Instructions  
1. Read this user’s guide before you operate your projector and save it for  
future reference.  
2. The lamp becomes extremely hot during operation. Allow the projector to  
cool for approximately 45 minutes prior to removing the lamp assembly for  
replacement. Do not operate lamps beyond the rated lamp life. Excessive  
operation of lamps beyond the rated life could cause them to explode on  
rare occasions.  
3. Never replace the lamp assembly or any electronic components unless the  
projector is unplugged.  
4. To reduce the risk of electric shock, do not disassemble this appliance.  
Take it to a qualified technician when service or repair is required. Incorrect  
reassembly can cause electric shock when the appliance is subsequently  
used.  
5. Do not place this product on an unstable cart, stand, or table. The product  
may fall, sustaining serious damage.  
6. This product is capable of displaying inverted images for ceiling mount  
installation. Please use suitable equipment for mounting the unit and  
ensure it is securely installed.  
Caution  
Always open the lens shutter or remove the lens cap when the projec-  
tor lamp is on.  
Do not look straight at the projector lens during operation. The  
intense light beam may damage your eyes.  
In some countries, the line voltage is NOT stable. This projector is  
designed to operate safely within a bandwidth of 110 to 230 volts, but  
could fail if power cuts or surges of more than10 volts occur. In these  
high-risk areas, it is recommended that a power stabilizer unit be used  
in conjuction with this projector.  
Do not place this projector on the top of cloth or carpet.
