This document provides instructions for updating the Rigol MSO8000 series digital oscilloscopes using the firmware package in the "MSO8000(ARM)_Firmware_Update" file.
 
[Notices]
    - Before updating, please review the "MSO8000 Release Notes.txt" file for details about the firmware update. 
    - This firmware does NOT support the MSO8000A models. For those models, visit the official website of Rigol.
    - Before powering on the oscilloscope, ensure that the HDMI interface is disconnected. 
    - Please make sure your USB drive can be read correctly. The MSO8000 series requires a USB flash drive formatted in FAT32 preferably less than 16G.
    - Please do not turn off the power or remove the USB drive during the update, as this may cause the instrument to malfunction.
 
[Updating Procedure]
    1. Copy the unzipped GEL file to the root directory of the USB drive. Please do not rename the file.

    2. Keep the instrument powered on, then insert the USB drive into the USB port (next to the Power button).

    3. Press the Menu button if menu is not shown on the screen, then select Utility -> System -> Help -> Local upgrade, then press OK to start updating.

    4. The update status will be shown on the screen of the instrument.

    5. After updating has been completed, the instrument will restart automatically.

    6. Verify that the firmware version has been updated by selecting Utility -> System -> About in the menu.

    7. Perform the self-calibration operation. Make sure that the instrument has been warmed up or has been operating for more than 30 minutes before the self-calibration.
        a. Disconnect all input channels.
        b. In the menu select Utility -> System -> SelfCal, then press Start to perform the self-calibration.
        c. This process may take some time. Please be patient. The notice will show when it's successfully done.
        d. After the calibration has been completed, restart the instrument.

[Troubleshooting]
    - If the instrument failed to read the update file from the USB drive,
      please try to replace the USB drive.

    - If the problem continues, 
      please try downloading the update file again and repeat the above steps.

    - If the problem still persists after performing the above two operations,
      please contact your regional support team for assistance.
