Warning
You cannot stop the upgrade once it has started. To avoid potential permanent
damage, do not turn off the instrument or remove the USB memory device during
the firmware update.
Note
If the instrument turns off and does not restart on its own, remove the USB memory
device and turn on the instrument by holding down the System (8) key, then
pressing the Power button. Keep pressing System (8) until the Anritsu splash
screen is displayed.
Be sure to use this key combination in order to perform a Master Reset while
turning on the instrument. Pressing the Power button alone may put the instrument
in an unrecoverable error state.
