3.2 Stopping/Restarting
Plotting of Track
When your boat is at anchor or returning to
port you probably won’t need to record its track.
You can stop recording the track, to conserve
the track memory, as follows:
1. Press the [MENU] key followed by the
CHART SETUP OPTIONS and TRACK
CONTROL soft keys.
2. Press the STOP TRACK soft key. The
indication “TRACKING” in the TRACK
STATUS window changes to “NOT
TRACKING”.
To restart recording the track, press the START
TRACK soft key at step 2 in the above
procedure.
When the fishing mode is selected, you can
stop or restart plotting the track with the soft
key only on the plotter display. Press the
[HIDE/SHOW] key several times to show the
STOP TRACK soft key. Press the STOP
TRACK soft key on the plotter display to stop
plotting of track. HOLD TRACK PLOTTING
appears approx. 2 seconds and own ship mark
changes to hollow circle. To restart plotting the
track, press the START TRACK soft key.
START TRACK PLOTTING appears approx. 2
seconds and the plotting restarts.
3.3 Track Plotting Method,
Interval
In drawing the track, first the ship’s position
(fed from the GPS receiver) is stored into the
unit’s memory at an interval of time or distance.
A shorter interval provides better
reconstruction of the track, but the storage time
of the track is reduced. When the track
memory becomes full, the oldest track is
erased to make room for the latest.
