P837 Auto False Echo Suppression
Use P837 and P838 during start up, if possible. It works ideally if the tank is empty or at
low levels. Only use this function if there is a minimum 2m distance from the radar unit to
the material. The agitator should be running, if the vessel contains an agitator.
Use this feature to adjust the TVT Curve
height to ignore false echoes on the Echo Profile by placing the TVT above the current
signal. Use P838 to set the Auto TVT length.

P837 will be preset to 1 by the factory. This is done to accommodate internal
antenna reflections.
