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.

securely locked by trying to move it up and down slightly.
Note:
• Do not let go of the camera arm if it is not locked.
Also hold the arm securely when pushing down the
camera arm. Otherwise, the camera arm section will
drop down of its own weight and this could result in
breakdown and/or injury.

• If the camera arm is locked, do not apply extra force
on the camera arm. This may result in breakdown.
• When storing, do not leave the equipment leaning
against, for instance, a wall. The equipment may fall
down causing breakdown and/or injury.
5
• When carrying around the equipment, make sure to
hold it by the base section
. Holding it by the cam-
5
era arm or the lighting device will put too much strain
on these parts. As a result the main unit may drop to
the floor and cause breakdown or injury.

• If VIDEO is selected on the INPUT SELECT button, the ON SCREEN ADJUSTMENT cannot be used.
• Under normal circumstances, it is recommended to use the lighting device and keep the AGC turned off. The images on the
monitor will be less gritty than those from the image signals that are electronically amplified.
• When the power is turned off, all settings go back to the initial values.
• When presenting negative film, please use a commercially available light box.

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
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?
No images
•
•
•
•
•
•
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?
Images are out of focus.
•
•
•
•
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.
Images are hazy.
Dust is visible
•
Is the lighting device turned on?
Is the setting value for IRIS suitable?
Dark images
•
•
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.
Stripe patterns appear on
images of printed text.
•
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.
Abnormal tone
•
•
If the surrounding area is dark, images may become gritty as the image signals are amplified
electronically by AGC. Use the lighting device.
Gritty images
•
•
•
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.
Beats appear in images
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.
Pressing buttons will not
operate the equipment
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 mate-
rials. 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).
