1.27 Electronic Plotting (E-plot)
10 operator-selected targets can be plotted elec-
tronically to assess their motion trends. Five past
positions are marked for each plotted target.
A vector appears as you enter a second plot for a
target and is updated each time a new plot is en-
tered for the target. The vector shows the target
motion trend based on its latest two plots.
Alphanumeric readouts for last-plotted or selected
target appear at the bottom of the display.
It should be noted that the vector and alphanu-
meric target data are not updated in real time, but
only when you enter a new plot.
E-plot requires ship's speed input (automatic or
manual) and a compass signal.
When speed is input by a navigator, own ship
moves in accordance with course; not heading.
Plotting a target
Before plotting a target, select PLOT or ALL on
the MARK & DATA DSP menu.
1) Place the cursor on the target you want to plot,
and press the PLOT SYMBOL key.
2) Watching the E-plot timer on the PLOT mode,
wait at least 30 seconds. Place the cursor on
the plot symbol and press the ENTER/SE-
LECT key. The plot symbol of the target
flashes.
3) While the plot symbol of the target is flash-
ing, place the cursor on the target again and
press the PLOT SYMBOL key. The plot sym-
bol shifts to the new target position and the
previous position is marked by a small dot.

Figure 1-23 Plotting
Note: If a certain target once plotted is not plot-
ted again within 12 minutes, the plot symbol of
the target flashes. If you want to continue plot-
ting this target, reacquire it within one minute,
otherwise, the target will be regarded as a "lost
target" and its plot symbol and target data will be
erased. The larger the plotting interval, the less
accurate the plotted target data. Plotting of each
target should normally be made every 3 or 6 min-
utes as far as possible.
