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.) (Page 115) for
instructions.
This feature can also be used if SITRANS LR200 displays a false high level, or the reading is
fluctuating between the correct level and a false high level.
