1. OPERATION

[ TX Rate ]: Change pulse repetition rate. Nor-
mally, the highest rate (10) is used. When in
shallow waters second reflection echoes may
appear between the surface and actual bot-
tom echo. In this case, lower the TX rate level.
The setting [MAX] automatically adjusts the
frequency and pulse length with depth. The
[S] setting, which requires speed data, selects
the TX rate according to your boat’s speed. 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 [Yes].
This is because of the communications speed
limitation between this unit and Shimano’s re-
ceiver.
