AUTO1, AUTO2, HARBOR
NOTE:
The AUTO function provides automated Gain, STC and FTC functions without the
need of operator’s control, giving an optimized radar picture while it is activated.
The
AUTO 1
is suited for coastal navigation. In this mode the picture is optimized for
short and mid ranges with reduced noise and weather clutters.
The
AUTO 2
is used for open sea navigation. In this mode the sea and weather
clutters are effectively reduced while the long-range performance is maintained.
The
HARBOR
mode is used for the navigation in a confined area such as a harbor,
inland waterway, canal, etc. where hard and tall objects give strong radar reflections
causing the picture to be saturated. Using this mode the Gain, STC and FTC are
effectively introduced to minimize such strong echoes while the picture definition is
maintained.
