4Color gradation factor
for “echo level” display
( * )
(1 to 36)
(Note 1) Changes the threshold levels for coloring echoes
with different strengths. (The higher the value, the
lower the thresholds, and vice versa.)
A gradation factor of 1 to 7 is recommended. The
higher (lower) the value, the greater the amount of
red (blue) in echoes.
Notice that the threshold shift dose not change the
receiver gain nor performance of the equipment,
although it changes echo color.
