important that you follow the instructions mentioned in this manual and marked on the 
product.
Caution
•To prevent shock, do not open the 
cabinet. There are no user serviceable 
parts inside. 
•Please read this user’s manual before 
you operate your projector. Save this 
user’s manual for future reference.   
•Do not look straight at the projector

it is recommended that you connect 
your projector through a power 
stabilizer, surge protector or 
uninterruptible power supply (UPS).
