Remote paging operations

Connect the projector to your PC or notebook with a USB cable prior to using the paging function. See "Connection" on page 15 for details.

You can operate your display software program (on a connected PC) which responds to page up/down commands (like Microsoft PowerPoint) by pressing PAGE UP/PAGE DOWN on the remote control.

If remote paging function doesn't work, check if the USB connection is correctly made and the mouse driver on your computer is updated to the latest version.

The remote paging function cannot work with Microsoft® Windows®98 operating system. Windows®XP or higher operating systems are recommended.

Freezing the image

Press Freeze on the remote control to freeze the image. The word “FREEZE” will display in the upper left corner of the screen. To release the function, press any key on the projector or remote control.

If your remote control has the following keys, please note that they cannot be pressed to release the function: LASER, #1, #4, PAGE UP/PAGE DOWN.

Even if an image is frozen on the screen, the pictures are running on the video or other device. If the connected devices have active audio output, you will still hear the audio even though the image is frozen onscreen.

Hiding the image

In order to draw the audience's full attention to the presenter, you can use ECO BLANK on the projector or remote control to hide the screen image. When this function is activated with an audio input connected, the audio can still be heard.

You can set the blank time in the SYSTEM SETUP: Basic > Operation Settings > Blank Timer menu to let the projector return the image automatically after a period of time when there is no action taken on the blank screen. The length of time can be set from 5 to 30 minutes in 5-minute increments.

If the preset time spans are not suitable for your presentation, select Disable.

No matter Blank Timer is activated or not, you can press most of the keys on the projector or remote control to restore the picture.

Do not block the projection lens from projecting as this could cause the blocking object to become heated and deformed or even cause a fire.

Locking control keys

With the control keys on the projector locked, you can prevent your projector settings from being changed accidentally (by children, for example). When the Panel Key Lock is

on, no control keys on the projector will operate except POWER.
