Occurrence Conditions
When the CF becomes full during writing
of photographed images to CF, writing is
repeatedly performed with the JPEG com-
pression ratio successively increased to re-
duce the size of the image file until it can
be successfully written to CF. This error
occurs when writing of the JPEG image file
fails after 10 retries at increasingly higher
compression ratios.
* The same applies in the case of the Mi-
cro Drive.
The power of the imaging circuit on the
MAIN PCB ASS'Y was not detected.
The power of the LCD PCB ASS'Y was not
detected.
Detection of the focus PI (photo-interrupter)
failed.
Writing of the photograph image to SDRAM
did not end within the specified time.
Free area could not be secured in the buffer
for the photograph image within the speci-
fied time in the continuous shooting mode.
The camera power was turned OFF while
the image was being recorded to the CF
Card/Micro Drive (while the green LED was
blinking). (The error code is displayed when
the camera is next turned ON.)
* This error may occur after E23.
The CF Card/Micro Drive could not be for-
matted properly.
Review of the photograph image failed.
