Preliminary measures in the case of errors:

  • Refresh the browser:
    In the case of problems, reloading the page is often all that's required - the easiest way to do this is to press the F5 function key. Alternatively, you can close the window and then open it again.
    After pausing, it can sometimes happen that the sound can no longer be heard. This is a known issue that can only be resolved by refreshing the page.

  • Check the sound output:
    If the sound is only barely audible or cannot be heard at all, check your sound settings under Start -> Settings -> Control Panel -> Sounds and Audio Devices. In the "Volume" tab, ensure that the device volume is set to maximum and that "Mute" has not been activated. By right-clicking in the video window, make sure that the player has not been set to mute. Check whether there is a general problem with sound output by trying to run a different sound file. Also check the cabling and volume of your speakers.

  • Changes in bandwidth:
    As a user of DSL broadband, it is often possible to switch to ISDN quality. Fault-free reception is possible with bandwidths of 64 kbit/sec or higher.

  • Display problems when using full-screen mode:
    You can output a video in full-screen mode by right-clicking on the video image and selecting "Zoom" or "Full-screen". The Escape (Esc) key restores normal mode.
    In this case, the screen may occasionally remain black once full-screen mode has been activated if your computer processor or graphic card does not offer sufficient performance. In this case, avoid displaying in full-screen mode.

  • Switching dial-up access providers:
    When there is a lot of Internet traffic, particularly early in the evening, there may be considerable fluctuations in the bandwidth available from your provider. If you have several alternative dial-up access options, correct display can be achieved by switching providers.

  • Automatic system check:
    The Service section of the Online Congress website includes a system check. This section provides a video stream with sound and signals for switching slides. If the result of the system check is positive, your system meets the relevant requirements. Otherwise, information will be provided regarding possible problems.
