- Press the auto focus button to focus.
- The covered area of the auto focus function is up to about 10cm above the stage surface.
Simple steps for viewing transparencies and x-rays:

- While observing the image on the TV monitor, adjust the zoom button to obtain the optimum size.
- When turning off the base light, press the [BASE] lighting button again.
- Use the upper lighting unit for viewing materials such as printer matter and 3-D objects. Use the base light for viewing slides, negative film transparencies and x-rays.
- When you press the lighting button, the indicator flashes, and after a few seconds, the fluorescent lamps illuminate.
- To turn the lamps off, press the lighting button again. It is not possible to simultaneously use both the upper lighting unit and the base light.
- It is advisable to use the upper lighting unit to obtain the clear image with better color rendering, especially when the stage is not sufficiently illuminated by room lights or where a 3-D object is to be viewed.
- Use this function to view negative film as positive images.
- Press the Neg/POs conversion button, so the indicator shows [N] (negative).
- Use this mode to view B&W materials such as documents.
- For normal use, set to [C] (color) mode.

- The Visual Presenter features a one-step auto focus function. Once focusing is completed, the auto focus function is released. Even if the object is moved, the focus remains unchanged.
- To focus the image with auto focus setting, set the zoom button at extreme telephoto position. This allows you to obtain a sharper image.
- It is difficult to automatically focus on an object under the following conditions. Select the manual focus mode for the following conditions:
- Objects containing little contrast
- Objects having a fine repeated pattern, such as lateral stripes, or a checkered pattern
- Bright object or one reflecting strong light

- Moving object
- Note: when using the manual focus during auto focusing, the auto focus function is canceled
- Press the focus button [N] or [F] for manual focusing.
- This function should be used to view 3-D objects. Any part of the object can then be brought into focus.
- Note: The coverage area of manual focusing is up to approximately 10cm above the stage surface.
