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.

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). 

5.

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.
