These are the installation instructions for replacing the firmware in a
TDS 3000C family oscilloscope with the firmware in this "zip" package.

Contents of this zip package:

    README.TXT       - this text file
    tds3000c.img     - binary firmware file
    version.dat      - ASCII text file containing new firmware version number


Instructions:

    1. You will need USB flash drive media with enough empty space for 
       TDS3000C.IMG (approximately 2.5 MB).

    2. Determine the version number of the firmware currently loaded into
       your TDS 3000C oscilloscope. You can determine which version you 
       have by turning on your oscilloscope and noting the version listed at 
       the turn-on screen.

    3. Determine the version number of the firmware in this zip package. If
       you do not already know this, you can open and read any one of the
       "version.dat" files included in this package.

    4. Copy TDS3000C.IMG to your media.

    5. Turn off the oscilloscope power.

    6. Insert your media into the oscilloscope USB port labeled
       "USB FlashDrive" and turn on the power.

    7. When prompted, start the firmware loading process by pushing the "OK
       Load New Firmware" menu button. 

    8. Wait for the new firmware to be loaded.  The process takes less than
       five minutes. At the end of the firmware load process the instrument 
       will reboot itself.

    9. Remove your media when prompted. The new firmware should 
       now be loaded into your oscilloscope.



Problems?

    If something goes wrong during the installation process, it may be
    necessary to start over by going to step 5 above. Here are some common
    reasons why the installation may fail:

    1. Incompatible media. Some older USB flash drives cannot be used with 
       the TDS 3000C family oscilloscope.  In this case please use different
       media.
    2. Improperly formatted media. Format your USB flash drive on a PC and 
       re-try the firmware update procedure.
    3. Removing the media too soon, before being prompted.

    If you are still unable to load the new firmware, please contact the
