You only hear soft rhythmic noises?

There are two reasons for this: Either the contents of the memory card have got mixed up, or the remains of leaking batteries affect the electronics. (In this case: Problems with leaking batteries?)

• To compare problems with the memory card, you can use another suitable memory card, for example, or you can first back up all the contents of your hörbert card with the on-board resources of your computer: Simply copy all the contents of the memory card into a folder on your computer. You can use this backup later. Tip: The hörbert software can create a table of contents on page “2”, which you can save on your computer with the files on the memory card.
• The easiest way to”repair” a messed up memory card is to format it and reload it.
  • Start the hörbert software on the computer, and check if you have the latest version (at the left of the bottom of page “1”: “Search for newer hörbert software”). If necessary, install the latest software while you’re at it.
  • If you now insert your memory card into the computer and select it in the hörbert software, you can format the card with the “memory card tools”. Attention: By formatting all data on the memory card will be deleted irretrievably! Be especially careful not to select another drive of your computer or that may be plugged into your computer.
  • After formatting, you can reload the card with the hörbert software as usual. As a test, it is enough to play 2-3 songs on each playlist to test the card. If you want to try again with your previous content, simply copy your backup copy from your computer back to the card.
