This chapter explains functions used when giving presentations and for using
the projector’s security functions.
Functions for Enhancing Projection
Muting the Image and Sound (A/V Mute)
For example, this can be used if you want to pause the projection for a
moment and focus the audience’s attention on what you are saying. Or if you
are making a computer presentation and you do not want to show details,
such as selecting different files.
You can temporarily turn off the image and sound in two ways:
When you close the lens cover, projection and sound are turned off. Open
the lens cover to restore projection and sound.
When you press the A/V Mute button on the remote control, projection and
sound are turned off. If you saved a user’s logo (see page 28
), you can set
it to display when you press the A/V Mute button (see page 35
). Press the
A/V Mute button again to restore projection and sound.
Using the remote control
Pressing the [A/V Mute] button
stops projection and sound.
Closing the lens cover stops
projection and sound.
Using the projector
p
If you’re watching a moving picture, the video source continues to play
while the screen is dark. You should pause the video if you wish to resume
playback where you stopped it.
The screen display in A/V mute can be chosen from black, blue, or a logo
by using "Extended" -"Display" - "A/V Mute" in the configuration menu.
