To measure the noise level, observe the value presented on the
dialog box.
We recommend that you do this test twice. First, do the test with all other hydroacoustic
systems (echo sounders, ADCP, sonars) turned off. Second, do the test with normal
operating conditions. This allows you to see how the other hydroacoustic systems affect
the operation and performance of your SU90 system.
