Follow the steps below to download and install (or reinstall) the latest operating software for the MediaMaster® MM100s:

  1. Download Update (ver: 4.0.25b5f85)
  2. Extract the files and review the included PDF license agreement (MM100s_OS_EULA.pdf).
  3. Save the three remaining files (highlighted below) to a USB thumb drive. (Thumb drive should be empty and formatted to FAT32 or ExFAT.)

    Note, these three files should be saved to the root directory (top level) of the thumb drive (not placed in a folder).
  4. Disconnect +12VDC power from the MM100s. This can be accomplished by removing its fuse, unplugging the 4-pin Power Connector plug, or by turning off the vessel’s main battery disconnect switch, if equipped.
  5. Insert the USB thumb drive into the USB port of the MM100s.
  6. Reconnect +12VDC power to the MM100s to begin its startup.
  7. In the following moments (about 2 minutes total), these three messages will appear in succession, just above the yellow line on the display screen:
    "Updating system files", "Running update script", and "Updating bootloader"
  8. When “Update Complete. Remove USB media” appears on the display screen, unplug/remove the USB thumb drive from the MM100s and disconnect +12VDC power from the MM100s (see step 4 above).
  9. Reconnect +12VDC and turn on the MM100s. Update complete.
