Depth
Displays (in Cm) when Doppler cursor is present.
Doppler Angle
(AC ##)
Indicates angle in degrees between the Doppler mode cursor and the angle
correction indicator. Displays when Doppler cursor is present. The Doppler
Angledisplays in red when the angle exceeds 60°. Velocities obtained when the
angle is greater than 80° are displayed as asterisks (***).
