Verify the following points
● Is the power plug connected to an AC outlet?
● Is the power switch turned on?
● Is this unit connected correctly to the projector or display?
● Is the brightness set to the optimum level?
● Are you sure that the pictures have been stored to memory? First store the
pictures to memory and then recall them.
● Is [EXT IN] or [SD CARD] of [SOURCE SELECTION] being selected? Select
[CAMERA].
● Is a XGA compatible projector or display used?
● Is the close-up lens attached?
● Is the object too close to the lens or is the top of the object at a height of more
than 50 mm from the stage surface?
● Did you shoot the surrounding objects with close-up lens attached? When shoot-
ing surrounding objects, remove the close-up lens.
● Did you enlarge the image size with the zoom after focusing was achieved?
Perform focusing after enlarging the image with zoom.
● With [FOCUS AUTO], focusing may be difficult depending on the object. Adjust
the focus using [FOCUS
,
● If the unit is connected to the projector, make sure that the projector is focused
correctly. Refer to the projector's instruction manual for focusing procedure.
● Is the close-up lens or camera lens dirty? Clean it with a commercially avail-
able cleaner.
● Are the side illuminations lighted?
● Is the brightness set appropriately?
● Dots in the printed matter may interfere with the pixels in the camera image
device resulting in colour stripes. In this case, change the image size slightly
with the [ZOOM] buttons.
● Have you adjusted the tone with the [WHITE BALANCE]?
● Make sure that the negative mode is not engaged.
● When this unit is used near equipment generating a strong electric wave, beats
may occur in the image. Keep this unit away from such equipment.
● In areas where the 50 Hz power frequency is used, flickering may occur on the
screen when a fluorescent light or mercury-vapour lamp is used. Use this unit
with the side illuminations lighted.
● When the [FREEZE], [PICTURE MEMORY], [EXT IN] or [SD CARD] is se-
lected, the camera image cannot be adjusted. Return to [CAMERA] image to
adjust.
● When brightness is insufficient, this unit may not work properly even if you
adjust the brightness. Press the [LIGHT] button to turn on the side illumina-
tions.
● When two buttons are pressed simultaneously, or a button is repeatedly pressed
without pauses, the unit may not operate correctly. When operating the but-
tons, do it one at a time with intervals between each press.
● Are there batteries in the remote control unit?
● Are the batteries exhausted?
The batteries provided are for operation check only. Install commercially avail-
able batteries for actual usage.
● Is the remote control unit being operated outside the effective range?
● Black or white spots may occasionally appear due to the characteristics of the
high-pixel CCD for graphics. If the image is enlarged with the digital zoom
function, spots may be particularly noticeable.
