CHARACTERISTICS
This equipment is a presentation device that enables presentation materials such as slides to be shown on a monitor screen.
•
Auto focus function automatically adjusts and corrects focus as required.
•
The x 16 electric zoom lens enables materials of varying size from a 35mm slide to a lateral B4 size paper to be presented on a
•
screen.
OPERATIONAL PRECAUTIONS
Do not leave the equipment in direct sunshine or close to heating appliances.
•
During operation do not cover the lighting device with flammable materials such as fabric or paper.
•
When the main unit needs cleaning, wipe it first with a damp cloth that had been soaked in solution of neutral detergent and tightly
•
wrung; then dry it off with clean cloth. Never use volatile solvents such as paint thinner, benzine, insecticide, etc. on the unit as they
may deform, discolour and damage it. Also do not immerse the unit in water, as it will result in breakdown.

Note:
• Do not let go of the camera arm while the lock release button is depressed. The camera arm section
will drop down of its own weight and this could result
in breakdown and/or injury.
• When pulling up the camera arm, make sure to pull
it up by holding the arm section. If you try to pull up
by holding either the camera section or the lighting
section, it may cause breakdown.

Rotate the camera head towards the direction of3until
you hear a click and then let the lens section face towards
the stage which is located directly below.

Carry out one or the other of the following connections depending on the type of a TV monitor image input terminal in
use.
*We recommend the use of a S-image output because it
can reduce bleeding at color borders.
Note:
• Signals that entered the VIDEO INPUT terminal can
only come out of the VIDEO OUTPUT terminal. If
you would like to use the VIDEO INPUT terminal
make sure to connect the signals to the VIDEO OUTPUT terminal.

TROUBLE SHOOTING
IPlease check the following list of possible problems and their solutions first. If you cannot solve the problem(s) after consulting the list,
stop using the product at once and contact your retailer or the nearest JVC customer service.
Problem Check points
No images
Images are out of focus.
Images are hazy.
Dust is visible
Dark images
Stripe patterns appear on
images of printed text.
Abnormal tone
Check the power cord is properly plugged in.
•
Is the power switch ON?
•
Are all the cables correctly connected?
•
Is the camera head set at the correct position?
•
Is the setting value of IRIS LEVEL suitable?
•
Is the correct signal chosen by the INPUT SELECT button?
•
Is the close-up lens correctly attached?
•
Isn’t the text material too close to the lens; is it placed more than 90mm above the stage?
•
Is the slide in the slide film holder over-magnified?
•
Auto focusing may at times cause difficulty in focusing. (See page 9)
•
Check the close-up lens or camera lens for dirt. If so, clean them using commercially available
•
lens cleaning products.
Is the lighting device turned on?
•
Is the setting value for IRIS suitable?
•
The halftone dot of printed text and the pixel of the microelectronics devices of the filmed
•
images by the camera may interfere with each other to cause coloured stripes. In such a case,
change the image size slightly using the ZOOM button.
If AUTO WHITE BALANCE is used: in the case of single color materials it may be difficult to
•
obtain correct white balance. If so, use the AUTO WHITE SET button to correct the tone.
If MANUAL WHITE BALANCE is used: correct the tone by increasing the setting values of
•
‘RED LEVEL’ and ‘BLUE LEVEL’ on the ON SCREEN ADJUSTMENT screen.
ENGLISH
Gritty images
Beats appear in images
Pressing buttons will not
operate the equipment
Tinting around letter edges
If the surrounding area is dark, images may become gritty as the image signals are amplified
•
electronically by AGC. Use the lighting device.
If the equipment is used near any appliance that emits strong radio waves, beats may appear in
•
the images. In that case, move the equipment away from the offending appliance.
If two buttons are pressed at the same time or a button is tapped on continuously, they may not
•
operate correctly. Press buttons one at a time.
Depending on the materials you want to present, using the ZOOM function at its maximum or
•
near maximum capacity may cause coloring around the edges of letters and lines in the materials. In that case the problem can be minimized by reducing the image size using the ZOOM
WIDE button or changing the image to B/W. Use the ON SCREEN Adjustment function to
change the image to B/W (See pages 11 & 12).
