Noise Level

The Noise Level button is located on the Horizontal menu.

This button provides a read-out of the current noise in the waters

surrounding the vessel. It is only used for test purposes. This

noise is caused by water ﬂow, mechanical disturbances from hull

and engine, and even from other electric or electronic systems on

the vessel. In order to obtain the best possible sonar result, the

noise level read-out must be as low as possible, and you should

read a value close to 47 dB.
