[TX Power]: Interference may appear on the screen when an
echo sounder having the same frequency as your own is being
operated in the vicinity of your vessel. In this case, lower your
TX power and contact the vessel to request them to reduce
their TX power. The higher the numeric the greater the TX
power. For the Setting tab, the TX power for high and low frequency can be set indi-
vidually. The [Auto] setting automatically adjusts TX power to display the bottom echo
optimally. The [Auto] setting is not shown for the [External fish finder] tab and when
the transmission mode is [Std] mode.
[TX Rate]: Change pulse repetition rate. Normally, the highest rate (20) is used. When
in shallow waters second reflection echoes may appear between the surface and ac-
tual bottom echo. In this case, lower the TX rate level. A high rate for fast speed; a
slow rate for slow speed.
Note: The TX rate may not change when [Pic. Sync] in the [Tankenmaru] menu is set
to [On]. This is because of the communications speed limitation between this unit and
Shimano's receiver.
[Freq Control]: Adjust the transducer frequency. When change the setting, keep in
mind these considerations.
• Set frequency which is suitable for detecting targeted fish.
• Shift frequency so as to reduce interference.
• Lower frequency to increase detection range.
• Raise frequency to improve resolution.
