Setting up Your Projector
Your MultiSync LT156/LT155/LT154 Projector is simple to set up and use. But before you get started, you must first: 1. Determine the image size. 2. Set up a screen or select a non-glossy white wall onto which you can project your image. Ensure that the power cable and any other cables connecting to video sources are disconnected before moving the projector. When moving the projector or when it is not in use, cover the lens with the lens cap. Selecting a Location The further your projector is from the screen or wall, the larger the image. The minimum size the image can be is approximately 25" (0.6 m) measured diagonally when the projector is roughly 3.7 feet (1.1 m) from the wall or screen. The largest the image can be is 300" (7.6 m) when the projector is about 40.1 feet (12.2 m) from the wall or screen. Screen and Projection Distance The following shows the proper relative positions of the projector and screen. Refer to the table to determine the position of installation.

Basic Operation of the PC Card Viewer Software
PC Card Viewer Utility is an application for editing documents, converting them into slides and storing them on CompactFlash cards as playback data (indexes) for presentations using projectors.
Operating the PC Card Viewer Function from the Projector (playback)
This section describes the operation for showing slides of presentation documents created using the PC Card Viewer function with the projector. It is also possible to make slides directly from the images projected with the projector.
Delete. Deletes a captured slide(s) or all the captured slides in the Capture specific folder. View.. Hides the tool bar while you are playing back. Pressing the MENU button or clicking with the right button of a mouse shows it again.
NOTE: If no CompactFlash card is inserted in the PC CARD slot, there is no signal, and a black, blue or logo background is displayed, depending on the setting.
Playback is stopped when SLIDE +/ on the remote control or button on the cabinet is pressed in Auto Play mode.

Projecting slides

1. Insert a CompactFlash card into the card slot. Insert the CompactFlash card with the side with the insertion direction arrow on the top.
* Press the eject button to eject the card.
2. Select the PC Card Viewer from the Source Select menu.
NOTE: Up to 12 indexes can be displayed on the list of folders. The folder in the right bottom is always a folder exclusively for captured images, but is only displayed when images have been captured. To display the list of folders when there are 13 or more indexes stored on the CompactFlash card, select "Edit index" from the PC Card Viewer software's "File" menu and move the index you want to display to within 12 indexes from the top of the folder index. For details on indexes, refer to the PC Card Viewer software's help folder.

3. Project slides.

Checking Show Folder List, means that selecting PC Card Viewer input displays a list of the folders in the CompactFlash card and if Auto Play is checked the projector automatically starts to play slides at the first slide of the folder you have selected. A tool bar will appear when you press the MENU button on the remote control or the projector cabinet or clicking with the right button of a mouse. Prev Drag Next Stop Select Delete Play Jump Setup View
The tool bar includes the following buttons: Drag.. Drags to move the tool bar (for USB mouse operation only). Prev.. Returns to the previous slide or folder. Or this lets you play slides back in reverse. Next.. Advances to the next slide or folder. Or this lets you play slides back. Play. Plays back automatically or manually depending on the setting on PC Card Viewer Options of the menu. This allows you to move on to the next slide when Manual Play is selected. Stop.. This allows you to stop Auto Play while you are playing back and to resume playing from the selected slide or folder when Auto Play is selected. Jump. Displays a list of slides while you are playing back. Select. Displays a list of folders while you are playing back. Setup. Displays the PC Card Viewer Options dialog box on Page 2 of the Setup dialog box.

Viewing Digital Images

Digital images can be played with the PC Card Viewer if the following conditions are met: If the image can be stored on an MS-DOS format CompactFlash card If the image can be stored in a format supported by the PC Card Viewer. With the PC Card Viewer, images on the card are searched for in directories and images in JPEG or BMP format are recognized as slides. Searchable directories are directories within two steps from the root directory, and searchable images are images within the first 12 files in the directory. Only file and slide switching are possible.
3. A tool bar will appear.
The tool bar includes the following buttons: Drag. Drags to move the tool bar (for USB mouse operation only). Capture. Captures an image and save it as a JPEG file in a CompactFlash card. Freeze.. Freezes and unfreezes images. Exit.. Exits the Capture function. Another option to exit the Capture function is to press MENU or CANCEL button on the remote control or projector cabinet.
NOTE: The maximum number of images recognized as slides within one directory is 128.
NOTE: You can compress a captured file (JPEG) using the Capture Options in the Setup dialog. See page E-37. NOTE: Captured images with higher resolution than the projector's native resolution cannot be displayed correctly. NOTE: File size of the captured image varies depending on the resolution of an input signal. Since an image data is compressed with the JPEG format, the image is slightly degraded. NOTE: An hourglass indicating that an image is being captured appears on the projector's display. Do not eject the CompactFlash card or turn off the projector's power while this icon is displayed. Doing so will damage the CompactFlash card data. If the CompactFlash card data is damaged, use a computer to repair the data. NOTE: The folder in the right bottom is always a folder exclusively for captured images. To display the list of folders when there are 13 or more indexes stored on the CompactFlash card, select "Edit index" from the PC Card Viewer software's "File" menu and move the index you want to display to within 12 indexes from the top of the folder index. For details on indexes, refer to the PC Card Viewer software's help file.
Uninstalling the PC Card Viewer Software
Even if you do now know the PC Card Viewer software's file names or where they are stored, the PC Card Viewer software files can be easily removed from the system using the "Install/Uninstall Applications" control panel in Windows. (Normally there is no need to perform this operation.)
