Why is the shutter not working and the film icon blinking on the LCD panel?
If the frame count is not displayed and the film icon is blinking on the LCD panel, the film has not been loaded correctly. Remove the film and reload it properly, ensuring the film leader edge is aligned with the mark on the camera. If the film is not loaded properly, the shutter will not work. (Page 49)
