Cleaning the Intake and Exhaust Vents
This Vision 10/12 is equipped with intake and exhaust vents to allow the flow of cool air through the projector and maintain the proper operating temperature.
You should periodically clean the vents by vacuuming them with a vacuum cleaner. Vidikron recommends doing this after every 100 hours of use, or more often if the projector is used in a dirty or smoky location.
To clean the intake and exhaust vents:
1.Press OFF on the remote control to turn off the power. Wait until the cooling fan stops.
2.Unplug the power cord.
3.Remove dust by placing the cleaner hose on the intake and exhaust vents.
