Warning

When updating from version r7.x (version lower than r8.0) to version e.g. r8.2, you must first update to version r8.0 (click here to download). Only then can you update freely to any version. This intermediate step is crucial!

  1. Upload the firmware file named device.upd to the USB drive.

  2. Connect the USB drive to the clock using the USB-C connector on the clock PCB.

  3. Open the clock menu and go to the SYSt system menu submenu.

  4. Setting item c2 to value 1 will activate the firmware update process.

    Hint

    First step of the Firmware update process is to load the USB device.

    The display will show a flashing FU:xx, where xx represents the result of the process:

    0:

    USB drive connected

    -1:

    USB drive not found

  5. If FU: 0 is displayed, the file transfer can be started by pressing OK button on IR remote controller or by pressing PB2L.

  6. If the file on the USB disc is OK, the message stops flashing and FU:xx is displayed with only flashing colons, where xx already repserents the percentage progress of the file transfer.

  7. If the file is invalid for the device, FU:-3 will flash or if the file is not found, FU:-2 will flash.

  8. When the file transfer is complete, the dONE message is displayed and the clock resets after 2 seconds to complete the update process.

    Note

    Until the file transfer starts, the menu can be exited by pressing ESC button on IR remote controller or by pressing PB1L.

    If the file transfer process fails and the copy process does not complete, the clock must be manually reset, as the clock control by the buttons or IR remote controller is ignored during the file transfer.
