4.Place the document whose image you want to project onto the document 
camera’s document stage.
 Be sure to place the document in the center of the 
stage, and do not let any part of the document 
extend off the edges of the stage.
 When placing a landscap e orientation document 
onto the document stage,  the top of the page 
should face towards the camera stand.
 Initially the monitor image will be projected, and so 
the image will appear a bit fuzzy.
 When the document camera senses that the document on the stage is not being moved, it will 
record its image and switch from the fuzzy monitor image to a high-resolution image (recorded 
image) automatically.
5.Now you can replace the document currently on the stage with another one.
This will switch to the recorded im age of the next document automatically.
NoteStep 5 above is what happens wh ile the Data Projector’s YC Camera application is configured 
with its initial default settings. The recorded image will not switch automatically if you have 
changed the “Operation Mode” se tting of the YC Camera application to “Manual Capture”. For 
more information, see “YC Camera Applic ation Setup Menu Contents” on page 48.

This section explains the various types of projection operations you can perform with the YC Camera 
application and how to configure YC Camera application settings.
Important!The procedures in this section assume that you have already connected the Document Camera 
to the Data Projector as explained under “Connecting the Document Camera to the Data 
Projector” (page 39), and that the Data Proj ector’s YC Camera application is running.
YC Camera Application  Projection Operations
The operations in this section are performed using the YC Camera function menu, which appears

To perform white enhancement on the currently projected image
NoteWhite enhancement causes the background of the projected image to be white enhanced, 
which helps to make  the text on a document easier to read.

produced the next time  you release the shutter will be projected in accordance with the 
settings on the YC Camera A pplication Setup Menu (page 46).
Important!You can perform white enhancement only on a projected image that has been skew corrected. 
For more information, see the note under “To perform manual skew correction on the currently

To perform manual skew correction on the currently projected image
NoteSkew correction automatically straightens the image of a document that is misaligned on the 
document stage of the document camera. Under its initial defaults, the YC Camera application 
is configured to perform skew correction automatically. You can also turn off auto skew 
correction. If you do, you can  use the following procedure to adjust image alignment manually.
 This operation will affect only the image that is  currently being projected. The projection image 
produced the next time  you release the shutter will be projected in accordance with the 
settings on the YC Camera A pplication Setup Menu (page 46).

Projecting the Screen Image of a Graphing Calculator
You can connect a CASIO graphing calculator to the Data Projector using a USB cable and project the 
calculator’s screen image with the Data Projector. USB connection of the following CASIO graphing 
calculators is supported.
fx-9860G Series
To project the screen image  of a graphing calculator
1.Set the graphing calculator up for data communication.
Enter the LINK Mode, and configure the “Wak eup” and “Capture” settings as shown below.
 Be sure to configure these communication settings before you connect the calculator to the 
Data Projector.
 See the user documentation that comes with your calculator for details about configuring 
these settings.
2.Turn on the Data Projector.
3.Use the USB cable that came with the grap hing calculator to connect it to the 
Data Projector as illustrated below.
 This will project an image of the graphing calculator from the Data Projector.
Important!If an hourglass figure appears in the image projected from the Data Projector when you 
connect the calculator, perform some operation on the calculator. This should cause the 
hourglass to disappear and enable normal projection.
 If the calculator does not operate properly af ter you connect it to the Data Projector, try 
disconnecting the USB cable from the calculator  and then reconnecting it. If this does not 
correct the problem, disconnect the USB cab le from both the Data Projector and the 
calculator. Turn the Data Projector off and then back on again, and then re-connect the 
calculator.
