  If you're getting error messages when downloading data to your PC from the Olympus Digital Camera, first, ensure the USB 2.0 cable is properly connected. Then, check that the main switch of the control box is set to the ON position. If you're using a hub, remove it.

  If the control box buttons of your Olympus Digital Camera aren't working, first ensure that the main switch of the control box is set to the ON position. Check that the AC adapter is correctly connected to both the control box and the power outlet. If the camera system is set for PC control via a USB 2.0 cable, operate it from the utility software on your PC. Alternatively, to operate from the control box, set the main switch to OFF, unplug the USB 2.0 cable, and then set the main switch to ON again. Finally, verify that the display resolution is set appropriately.

Why can't I record a picture when pressing the EXPOSE button on my Olympus DP20?
- C
  Cynthia MoyerSep 3, 2025
  If you cannot record a picture by pressing the EXPOSE button on your Olympus Digital Camera, release the EXPOSE button and wait for more than one second before pressing it again, especially if data is being written to the CF card. If the memory gauge bar indicates a full condition (4 bars), wait until the indication becomes 0. If the CF card is full, use another CF card, erase unwanted pictures, or download existing pictures to your PC and then erase all pictures from the CF card. Ensure the CF card is fully inserted.
