* Updating the Camera Software

 1. Download the file MX_preinstalled_apps-2021-02-24.app to your computer.

 2. Make sure that the file has been transferred completely. Please find the SHA256
    checksums in the "Checksums_*.sha256" files.

 3. Make sure that the camera fulfills the requirements listed above. Check
    the information under "Admin Menu > Hardware and Release Information" on the
    camera.

 4. Make sure that you are connected directly to the camera, without any proxy
    server in-between. Disable any proxy servers. Microsoft Internet Explorer:
    "Tools > Internet Options > Connections (tab) > Settings (in LAN Settings) >
    Proxy Server".

 5. Restart the camera.

 6. Log onto the camera as administrator, open "Admin Menu > Upload system
    Software" and read the Important Notes. Select the file
    MX_preinstalled_apps-2021-02-24.app and start the upload.

    CAUTION:
       - Never disrupt the procedure while the camera is uploading or
         rewriting its flash memory. If this has happened anyhow, the camera
         will automatically boot the backup system (the title bar in the browser
         interface is red). The backup system only allows updating the system
         software.

       - The upload procedure may take several minutes, depending on the quality
         of the internet connection.

       - The camera LEDs will show a specific pattern while uploading.
         Please read the manual for the meaning.

       - During the procedure, the browser windows may not be updated
         properly.

 7. Upon completion of the upload, the camera will display a message. Read
    this message carefully.

 8. If the upload has finished successfully, restart the camera. If the upload
    was not successful, do not reboot the camera. Restart the upload process and
    wait until the upload has finished successfully.

    If the camera detects a faulty operating system, it will boot its backup
    operating system (the title bar in the browser interface is red); in this
    case, you should update the system software again.
