2.4 Color Rejection of Weak
Echo
Color Rejection
The color of weak echo can be rejected.
Rejecting noise on the entire image and weak

to see the school of fish. It is the convenient
function when displaying the echo stronger
than the specific signal. (Setting: 0 ~ 50 %)

Noise Rejection
The influence of noise can be reduced.
Due to echo reflected from plankton and trash,
the speck-like noise may appear on the entire
image. Setting the [Noise rejection] reduces the
speck-like noise and makes it easier to see the
image of school of fish. (Setting: 0 ~ 10)
The greater the set value becomes, the
stronger the effect of noise rejection becomes.
