sired target.
w Push [TARGET]/[ ] for 1 sec. to select the tar-
get for tracking.
• 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.
■ Plotting marks
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.
■ Course and speed vector
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”.
