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
TVT setup (2.8.7.)
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.
