If the power supply stops or the serial communication
cable comes off during the firmware uploading, this may
lead to destruction of the Flash Memory. Do not perform
any other operations until "Complete" is indicated.


When the firmware uploading is performed, Hyper
function, Direct Print function, and Print mark function are
erased at the same time. Therefore, after completing the
uploading, these three functions have to be re-installed by
using the Uploader, which should be included in the same
package as the camera.
Be careful not to take the first beep sound (indication of the
operational change from "Reading" to "Writing to the Flash
Memory") as the ending of the whole operation.
When the operation is completed, the second beep sound is
emitted and a message "Complete" is indicated on the
screen. Make sure that the message "Complete" is
indicated on the screen before getting off the program.
