in the [TX/RX Setting] menu ([S] tab). The larger the value, the lower the reverberation
effect, which makes it easier to see the echo signal. The setting range is 0-3.

Setting between 1 and 3 : Echoes
are gradually displayed and afterglow remains on the screen longer as the setting is
increased.
Setting between 4 and 7 : Echoes are quickly displayed and afterglow re-
mains on the screen longer as the setting is increased.
