[Transmission Power] Set the TX power level manually. Inter-
ference may appear on your display

nearby. When this occurs, lower the

ceived in sequence are seabed echoes.
If the depth indication is not stable in the
default setting, adjust the bottom level

near the seabed from the seabed echo,
increase the bottom level. [-40] to [40]
