Possible Cause and Recommended Action
The image may not be focused properly. When composing the
image, make sure the subject is located inside the focus frame.
1)If ? (Flash Off) is selected as the flash mode, change to
another mode (page 33).
2)If the battery is dead, charge it (page 15).
3)If a BEST SHOT scene that uses ? (Flash Off) is selected,
change to a different flash mode (page 33) or select a
different BEST SHOT scene (page 53).
The flash unit may be malfunctioning. Contact a CASIO service
center or your original retailer. Note that though the flash will not
fire, you still can use the camera for non-flash shots.
The battery may be dead. Charge the battery (page 15).
1)You may be using Manual Focus and have not focused the
image. Focus the image (page 64).
2)You may be using ´ (Macro) for scenery or portraits. Use
Auto Focus for scenery and portrait shots (page 64).
3)You may be trying to use Auto Focus or ) (Infinity) when
shooting a close-up shot. Use the ´ (Macro) for close ups
(page 64).
Shooting a very brightly lit subject can cause a vertical band to
appear in the monitor screen image. This is a CCD
phenomenon known as "vertical smear", and does not indicate
malfunction of the camera. Note that vertical smear is not
recorded with the image in the case of a snapshot, but it is
recorded in the case of a movie.
1)Sensitivity may have been increased automatically for a dark
subject, which increases the chance of digital noise. Use a
light or some other means to illuminate the subject.
2)You may be attempting to shoot in a dark location with ?
(Flash Off) selected, which can increase digital noise and
make images appear coarse. In this case, turn on flash (page
33) or use lights for illumination.
3)Shooting with a high ISO sensitivity setting or with the
Lighting feature can cause an increase in digital noise. Use a
light or some other means to illuminate the subject.
