These are the installation instructions for updating the firmware
in a 5 Series MSO oscilloscope using your downloaded 5SeriesMSO 
firmware update zip file.

Contents of this zip package:

    install.txt       - this text file
    releaseNotes.txt  - describes differences between firmware versions
    firmware.img      - oscilloscope firmware file readable by 5 Series MSO

    Applicable open source licensing references.

Instructions:

    1.  Unzip the 5SeriesMSO_v_x_xx_x.zip file and copy the file 'firmware.img'
	to suitable USB media in the root or topmost folder. Most brands of 
	USB flash drives and USB hard drives are suitable media.

    2.  Check to make sure there are no other files in that folder that
        have a file suffix of ".img". For example, there must not be any
        files named firmware.img. If you have multiple .img files, the
        oscilloscope may not load the correct one.

    3.  Insert the USB media into any of the USB Host ports on the
        front of the oscilloscope. (The host ports on the rear of the
        oscilloscope may also be used.)

    4.  Wait for a dialog to appear and once it does, follow the
        instructions. There are multiple confirmation screens to
        click through and you must accept the license agreement.

        After a few seconds, the screen should display a message stating
        that the firmware upgrade procedure is in progress.

        Do not turn off the oscilloscope or remove the USB media
        until prompted to do so!

    5.  When the screen says that the upgrade is complete, turn off
        the oscilloscope.

    6.  Remove the USB media.

    7.  Turn on the oscilloscope.

Currently Installed Version:

    The firmware version currently installed in the oscilloscope is shown
    in the About menu, accessible from the Utility menu.

Troubleshooting:

    - If the firmware does not load, verify that the USB media is
      supported by the oscilloscope. Click the File menu and
      attempt to save a setup to the USB media. If you cannot save
      and recall .set files, the USB media may not be supported.
      Try another brand of USB media. If other brands do not work,
      try one of the other USB host ports on the oscilloscope. There
      are three host ports on the front and two on the back of the
      oscilloscope.

    - If the firmware does not load and the USB media otherwise works
      fine, then the firmware file may be corrupted. Try downloading
      the firmware again.
