13. Now click the Process Firmware Update button to initiate the second stage of the procedure. The firmware

image that you just uploaded is being prepared for use by the sensor.

14. A second progress bar is shown.

Note: This step should take approximately 70 seconds. If it completes in less than 10 seconds an error occurred. Instead

of continuing, perform the
