When you turn the zero line (transmission line) rejection
on, the line is not shown, which allows you to see fish
echoes near the surface. The width of the line changes
with the transducer used and installation characteristics. If
the width of the line is 1.4 m or more, select [ON].
Adjust the width of the zero line

Select on to synchronize with external sounder's keying

The default bottom level setting (0) determines that two
strong echoes received in sequence are bottom echoes. If
the depth indication is not stable in the default setting,
adjust the bottom level here. If vertical lines appear from
the bottom echo in the bottom lock display, lower the
bottom level to erase the vertical lines.
If you can not identify the fish near the bottom from the
bottom echo, increase the bottom level.
If the gain setting is wrong, or there is a difference in the
gain between the low and high frequencies, you can
balance the gain for the two frequencies here.
