Olympus DS 30 Handheld Digital Voice Recorder: screen problem

Hi. I just purchased my Olympus DS 30 and find the LCD screen virtually impossible to read. All the choices and icons appear (dimly) in see-through layers, so I'm basically seeing everything at once, with no ability to look at any one thing at one time. The manual is no help, and not just because it directs the reader to pages where the required information is nonexistent. Help??
