Passage of time
•Dotted square symbol appears on the cursor.
•Target identification number, bearing, distance readout, course (CSE), speed (SPD), CPA and TCPA appear in the information screen.
•Timer starts to count the progressing time.
•The vector appears on the target, after the progressing time of 20 sec. has passed.
•It changes to the circle display of a solid line and a vec- tor display, and tracking operation is decided, after the progressing time of one min. has passed.
•When the target which is following disappears, a mark changes to a lozenge and is blinked. A mark disappears after one min..
•When a target advances within a setting value, a mark changes to a triangle, blinks and sounds alarm sound. Alarm sound will be cancelled if one of key is pushed.
•To cancel the target setting, move the cursor on the tar-
get, then push [TARGET]/[ 
] for 1 sec.
•[TARGET]/[ 
] is pushed for changing the display of EBL/VRM etc. to target information.
•In order to choose target which displays information,
cursor is united with target and [TARGET]/[ 
] is pushed.

There are 5 kinds of plotting marks.
: Selected, uncalculated mark.
: Selected, calculated mark.
: Normal, calculated mark.
:CPA/TCPA alarm mark. The target is close to within a minimum range and time. Alarm emit indicator. Push [TAR-
GET]/[ 
] to cancel the alarm.
:When the tracking of a target disap- pears.
The vector indicates the target’s predicted, true or rel- ative course and speed.
•Vector time may change depending on the TRAIL TIME set- ting. (see VIDEO menu, p. 6)
•The tip of the vector shows the target’s predicted position after a certain time, which has been selected in the “TRAIL TIME”.
