This firmware update is very important and must be installed immediately if your hörbert was manufactured before the 7th of February 2022. Without this update, the processor module of your hörbert may irreparably damage itself!

This firmware contains:

  • Protection against a processor module error. In collaboration with the manufacturer, we were able to include a protection that must be installed BEFORE the processor module spontaneously destroys itself.
    This protection will be included in all future firmware updates.

  • Extended playtime through more precise measurement of the shutdown voltage of the batteries

  • 100x longer standby time!

  • More stable card recognition without considering the card contact

  • Additional commands for the PlaylistLanguage for controlling hörbert with external buttons

  • … as well as many very technical detail improvements.
