Refer also to the LoggerNet user’s manual for additional information. Many tests may be more
useful if something does not work as expected. Using port tests and flag tests are of particular
usefulness in troubleshooting problems.

5.3 Start a Profiling Sequence
Once you are satisfied with the results of your pre-deployment tests in Setup Mode, you are
ready to start a profiling sequence. Presumably your sonde is in a simulated depth profiling
environment, whether it outside in the water or on a test setup inside.
To begin set Flag 2 OFF and set Flag 5 ON. You may leave the Ports and Flags screen up to
monitor activity. When communication takes place, these screens will provide updates.
Remember that actual events and the communication of these events may not be at the same
