This tool helps the user to control the operating state of the four transponders. The control is
made via a frequency graph for each hydrophone. Such a display is shown below. For each

of this magnitude over time.
This tool is available with the appropriate version of Java and of
the Web browser. Compatible versions are available in the release note.
