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 following:
RNG/BRG (Range/Bearing): Range and bearing from own ship to the
COURSE/SPEED (Course/Speed): Course and speed are displayed for the
CPA (Closest Point of Approach): is the closest range a target will approach to own ship. Do not mix it with the operator preset CPA alarm limit.
TCPA: The time to CP A measured with present speeds of own ship and the targets. Both CPA and TCPA are automatically cal- culated. When a target ship has passed clear of own ship, the CP A is displayed and the TCPA appears as “**.*”. TCPA is counted up to 99.9 min. and beyond this it is indicated as TCPA>99.9 min.
