Functions for Enhancing ProjectionHiding the Image Temporarily (Shutter)
You can use this when you want to focus the audience's attention on what 
you are saying, or if you do not want to show details such as when you are 
changing between files during presentations from a computer.
Make sure that the Shutter Button is set to Electric Shutter from 
Operation in the Extended menu.
Procedure
Each time you press the buttons, the electric shutter closes or opens.
q
•When the shutter is closed and no operations are performed for about 30 
minutes, the projector enters Sleep Mode and turns off automatically. If 
you do not want Sleep Mode to activate, change the Shutter Timer setting 
to Off from Operation in the Extended menu. sp.67

Freezing the Image (Freeze)
When the freeze function is activated on moving images, the frozen 
image continues to be projected on the screen, so you can project a 
moving image one frame at a time like a still photo. Also, you can 
perform operations such as changing between files during presentations 
from a computer without projecting any images if the freeze function is 
activated beforehand.
