I recently dug out my IUXS X-1 and managed to take a few photos on it until it decided to stop working. On the screen in a box on the bottom right there is a capital H flashing and along with it there is a dashed line across the top of the screen, also flashing. I have no idea what these symbols mean and can't find an answer in my manual. I can turn all the dials and the shutter will not go. Can you tell me what the symbols mean and what i should do to rectify this issue?
