Attention
Leave a clearance of at least 50 cm so that the ventilation opening on the rear panel will not be blocked. •
Set up the projector so that air can flow freely around the rear of the projector without staying still. In addition, •
leave a space of 30 cm or more at the sides so that the hot air coming out from the air outlet vents does not get
drawn in through the air intake vents.
Set up the projector with a space of 40 cm or more at the front so that the air filter can be replaced.
•
When the projector is to be placed inside a box and used, ensure the structure has a duct or the like to •
discharge air from the box, leave the clearances shown in Fig. 2, and ensure the temperature during operation
remains within the 0 C to 35 C range.
