Auto False Echo Suppression
If you have a vessel with known obstructions, we recommend using Auto False Echo
Suppression to prevent false echo detection. See
(2.5.10.) TVT setup
for instructions.
This feature can also be used if the display shows a false high level, or the reading is fluctuating
between the correct level and a false high level.
