Positioning Your Document on the Stage
Place your document with the top near the rear of the stage. If you need to change the orientation of the document, rotate the camera head 90° to the right or 90°/180° to the left.
Some documents can pass through the rear of the document camera.
Use the paper pass-through slot to position these documents as needed.

Adjusting the Lighting
For presenting printed material or 3-D objects, the two lamps will provide ample light. If the ambient lighting in the room is sufficient, however, you may obtain a better image with the lamps off. Press the

Adjusting the Image
Once you see your image, you may need to make certain adjustments:
To zoom or focus your image, see the next section.
To freeze the image on screen, see page 16.
Zooming and Focusing Your Image
When you turn on the document camera, the Auto Focus feature is turned on and the indicator light is lit.
Use the Tele button on the control panel to enlarge the image, and use the Wide button to reduce it. The document camera will automatically focus the image. Once the zoom or focus is set for a flat document, you probably won’t have to adjust it again for subsequent documents.

Freezing the Image
If you need to change documents during a presentation, you can freeze your image by pressing the Freeze button. This way, your audience will have an image to view until the next document is ready.
Press the Freeze button again to display your next document. You can also use the Freeze feature to capture a single frame of a moving object.

Using the Camera Head as a
Conventional Video Camera
By adjusting the camera head to a horizontal position, you can use the document camera like a conventional video camera. And since the camera output is NTSC, you can present true motion video.
To view walls or distant objects, remove the close-up lens by unscrewing it counterclockwise.

Once the camera head has been placed in a horizontal position, rotate the camera head 180° to the left to present objects right-side up. You can also rotate the camera head 90° to the left or right to change the orientation of the image.
