Terminating Tracking of Targets
When the Auto Plotter has acquired 10 tar- gets, no more acquisition occurs unless tar- gets are lost. Should this happen, cancel tracking of individual targets or all targets by the procedure described below.
Individual Targets
Place the cursor (+) on a target which you do not want to be tracked any longer by operat- ing the omnipad and press and hold down the [SELECT/CANCEL] key.

To turn ARP data on;
1.Press the [MENU] key.
2.Select the "DISP DATA".
3.Press the [ACQ/ENTER] key to select the message for "ARP" or "NAV and ARP ".

CAUTION
At the speed under 5 kts the target data is displayed with a delay because of filtration.
Place the cursor on a wanted target and press the [SELECT/CANCEL] key. Data on the se- lected target is displayed at the bottom of the screen. The symbol of the selected target gets twice as large as the normal circle. The data includes the follows;
RNG/BRG (Range/Bearing): Range and bearing from own ship to the
COURSE/SPEED (Course/Speed): Course and speed are displayed for the last- plotted or selected target with suffix "T" (True) or "M" (Magnetic). For true bearings suffix "T" is used in case of gyrocompass input and suffix "M" is used in case of magnetic com- pass input.
CPA (Closest Point of Approach) is the clos- est range a target will approach to own ship. Do not mix it with the operator preset CPA alarm limit.
