Projector Installation Notice 
 Place the projector in a horizontal position 
The tilt angle of the projector should not exceed 15 degrees, nor should the projector be installed in 
any way other than the desktop and ceiling mount, otherwise lamp life could decrease dramatically. 
   
PPPrrreeefffaaaccceee   
 Allow at least 50 cm clearance around the exhaust vent. 
  
 
 
 
 
 
 
 
 
 
 
 Ensure that the intake vents do not recycle hot air from the exhaust vent. 
 When operating the projector in an enclosed space, ensure that the surrounding air temperature 
within the enclosure does not exceed 5 – 35°C while the projector is running, and the air intake and 
exhaust vents are unobstructed. 
 All enclosures should pass a certified thermal evaluation to ensure that the projector does not 
recycle exhaust air, as this may cause the device to shutdown even if the enclosure temperature is 
with the acceptable 5 – 35°C range. 
Power Safety 
 Only use the supplied power cord. 
 Do not place anything on the power cord. Place the power cord where it will not be in the way of 
foot traffic. 
 Remove the batteries from the remote control when storing or not in use for a prolonged period.
