NOTE

The relative exclusion zone is predominantly shown for sea clutter at close

range (approx. 3 nm).

However, as well as the sea clutter some targets will also be ignored. The

master must be aware of this situation.

This example (see Figure: 2−48) shows a ring centered on your own ship, which

may be useful when the sea conditions or observation of buoys near own ship

produces numerous false alarm echoes from waves. The exclusion zone will

inhibit the auto acquisition function. This function can be used temporarily or left

on to eliminate acquisition of false echo effects from the ship structure. The

alternative for preventing false echoes is sector blanking, which must be

commissioned by a service engineer with shipyard approval.

The range area can be individually adjusted using the editing marks.
