Your projector is setup and ready to display your presentation about 3 seconds after powering on, with the NEC quick start function. The quick power off function stops the cooling fan immediately after turning off the power to the projector, which makes it possible to remove the projector quickly. For a rapid shut down, the projector can be turned off without powering off the projector using the direct power off function and a power strip equipped with a switch and breaker.¤¤This projector employs the carbon meter indicating the reduced amount of CO2 emissions in eco mode. Visually confirm the numerical value indicating the reduction in CO2 emissions in comparison with normal mode operation.¤¤By using passwords, the projector cannot be used by unauthorized persons. It is impossible to project an image unless the proper password is entered. Since the main unit has a security chain opening, unauthorized removal of the projector is prevented by inserting the security cable or wire commercially available into the opening.
