Make sure that the stage surface is not exposed to strong light from the outside of the equipment.

Carry the equipment with care.

Please carry the equipment by holding the sides of the body. Also take care not to give strong shocks to the body.

Do not touch the camera lens directly with your hand. Also, do not use this equipment in a place containing much dust or cigarette smoke.

Fingerprints or smear on the camera lens will make normal image shooting impossible.

When the camera lens has become dirty, clean it with a commercially available camera lens cleaner. In doing so, take care not to damage the lens.

Stage surface

Clean images cannot be obtained if the stage surface is smeared, damaged or discolored. Take care to protect the stage surface from a splash of any volatile substance, damage or dirt.

Do not leave the equipment in places where the equipment may be exposed to direct sunshine or any heating equipment.

When the body becomes dirty, wipe the dirt off with a well-wrung cloth wetted with a neutral detergent or suchlike and then wipe with a dry cloth. Do not splash thinner, benzine, insecticide or other volatile substance on it. Otherwise the equipment may deform, discolor or develop trouble. Also never wash the equipment in water, which will lead to a failure.

Disposal

Preparations before Use

Connecting the Cable and Setting the Output Mode

Connect the cable to the equipment that displays the image from this equipment. A selection can be made from the RGB output and the video output. However, it is necessary to set the output method with the dip switch on the back panel before turning on the power to this equipment.

■ For RGB output

Set the dip switch 4 to OFF.

Connect the RGB monitor output terminal 1 (RGB-OUT 1) to the RGB input terminal of a projector, display or other image equipment.

RD-230C MONITOR USB RGB-FN VSSD 1 RGB-OUT 1 Set dip switch 4 to OFF. Supplied RGB signal cable Display Projector

With dip switch 5 set to ON, the same signal can be outputted from two systems by connecting a projector or display to the RGB monitor output terminal 2 (RGB-OUT 2).

NOTE:

- In the case of RGB output only, the RGB output signals from a PC, for instance, may be outputted via this equipment. For such an application, connect the RGB input terminal to the RGB output terminal on a PC or suchlike.

Set dip switch 4 to ON. Commercially available video cable or S-video cable TV or the like

NOTE:

- With dip switch 4 set to ON, the source selection 'EXTERNAL' cannot be selected.

■ Connection of a simple monitor

A simple monitor may be connected to the Monitor output terminal for use with RGB output or video signal output.

RS-232C MONITOR USD RSD-IN VIDEO 2 NGB-CUT 1 SIMPLE MONITOR Commercially available video cable

Camera image is always being displayed, so that when replacing data, it is possible to see in advance whether the next data, larger in size, will be within the display range or not.

NOTE:

• The display image on a simple monitor may be slightly wider in the horizontal direction than that of a projector or a display.
• The display range may sometimes vary depending on the performance characteristics of a simple monitor or the type

Setting the Camera Arm

As illustrated, raise the camera arm gently in the indicated direction while holding the body down with your hand.

When the angle between the stage and the camera arm is 60 degrees, there is a click with which the camera arm gets fixed momentarily. Normally use the equipment in this 60-degree position. Though the camera arm may be raised to a position of 80 degrees, do not attempt to raise it any further.

CAUTION

Be sure to hold the body down with your hand when raising the camera arm. Otherwise, the body may lift up to cause injury.

How to Use

Turning Power On

Set the power switch on the back panel to ON (I).

All the indicators on the control panel light up for about ten seconds.

Shooting the Material (Data)

①Place your material on the stage.

②Turn on the main light or turn on the base light, depending on the lighting in the room or the condition of the material to be shot.

Shooting the Surroundings

Turn the camera head toward the object you want to shoot.

Horizontal direction B A Vertical direction Normal position

NOTE:

• The camera head does not turn vertically in your direction (A). Forcible turning may cause trouble.
• For turning in the horizontal direction, do so by holding the part B of the camera head.

NOTE:

- When the material reflects light, turn off the main light. Also, try shooting obliquely by adjusting the camera arm angle.

Lighting Guidelines

	Main light *	Base light
Printed matter	ON	OFF
Three-dimensional object	ON	OFF
OHP film and other see-through material	OFF	ON
Reflective material, such as glossy paper	OFF	OFF

* When the room is full of light, better images may be obtained by turning off the main light.

- Adjust the brightness by using both the ON/OFF of the main light and the 'BRIGHTNESS' button.

Correcting Trapezoidal Distortion at Oblique Shooting

The trapezoidal correction function can be used to correct trapezoidal distortion that occurs when the camera arm is moved from the normal position (60°) to a higher position (80°) and material is shot from an oblique direction.

The wider base is adjusted to the narrower base to obtain an image with reduced distortion.

Use this function when showing a material of A4 vertical size within a screen or when avoiding the reflection of external light or light from the main light on the material to be shot.

60° (normal position)

The indicator of the 'ON/OFF' button of KEYSTONE lights up when the trapezoidal correction function is working. To turn off the trapezoidal correction function, press the 'ON/OFF' button (indicator going out).

If the trapezoidal correction function has not corrected distortion completely, make fine adjustment with '+' / '-'button of KEYSTONE.

Indicator Control Panel Data Input Data Output Control Panel Data Input Data Output

NOTE:

• The trapezoidal correction function does not work when the camera arm is lower than the normal position and material is shot from an oblique direction.
• Turn off the trapezoidal correction function when shooting a solid body from an oblique direction.
• If you adjust the input signal using an auto-adjusting function of a projector or display during the operation of the trapezoidal correction function, the image may not sometimes be displayed properly when the camera arm is returned to the normal position. In such a case, please carry out the automatic adjustment again.

During the use of trapezoidal correction function:

Using Image Memory

You can store images (up to 8 images) in advance and output them later.

■ Storing images

① Select the image memory to be used by operating 'UP' or 'DOWN'.

The No. of the image memory selected is displayed by the indicator.

② Press the 'CAPTURE' button.

The image is stored in the image memory.

LOG 17 SOLVENTATION SOURCE ① Indicator ②

NOTE:

• Image cannot be stored when EXTERNAL or MEMORY has been selected in source selection.
• Capturing during the use of digital zoom will result in the storage of image before the use of digital zoom.

■ Outputting images stored in image memory

① Press the 'MEMORY' button in source selection.

The contents of the image memory currently selected are outputted.

Select the image memory by pressing the 'UP' or 'DOWN' button.

Transferring Image Memory Contents to PC

By the use of a USB cable, the contents of image memory can be transferred to a PC in the form of a JPEG file.

■ How to transfer

This equipment will be recognized as the drive by "My Computer" on the PC and the contents of image memory are displayed as a JPEG file. Copy the JPEG file and transfer it to your PC.

NOTE:

• “U” will be displayed by the indicator for an applicable image memory No. during communication with a PC, such as when the contents of an image memory are being transferred to the PC.
  During the display of "U," you cannot operate this equipment. Please wait.
• The date and time captured is not stored as data for JPEG file.
• Images captured during the use of the trapezoidal correction function are displayed in the state before correction on a PC display.

Turning Power Off
