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 projector 
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.
