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-

: Indicates the tracking of a target disap-
pears.
The vector indicates the target's predicted, true or rela-
tive course and speed.
• The vector time may change, depending on the VECT TIME
setting. (see TARGET menu, pp. 7, 19)
• The tip of the vector shows the target's predicted position
after the time selected in the "VECT TIME."
The plot displays the target's past positions as 5 dots,
during each specified tracking interval.
• The target track may change, depending on the TARGET
TRACK setting. (see TARGET menu, pp. 7, 19)
q Target goes straight.
w Target turns right.
e Target reduces speed
(dots are closer together behind
