About monitoring routes
14.2 How to Stop Monitoring a Route
In the Voyage navigation mode, click the [Route] and [Unselect] buttons.
14.3 How to Select What Parts of a Route to Display
You can specify what parts of the monitored route to display. Click the [DISP], [SET]
and [Symbol DISP] buttons on the InstantAccess bar.
z When you choose a route for monitoring, the messages shown below appear, on the
[Select Route] dialog box or in a message window, when a route cannot be opened
for monitoring.
• "Impossible turn at waypoint XX" (XX=waypoint no.). Geometry of the route makes
it impossible for the ship to accomplish a turn. Modify the route to make the turn
possible.
• "Unchecked / Check condition differs". The route has not been checked. Check the
route, on the [Alert Parameters] page.
• "Monitored in the NAVI mode". The route is currently being monitored.
• "More than one WPT needed". The route has only one waypoint. Add more way-
points to the route.
• "Route monitoring cannot be started. Please check ship’s position and conditions."
Click the [OK] button to close the message. Check ship’s position and conditions
of the route.
z If you have small-scale chart(s) on display that have the whole eastern/western (0-
180°E/0-180°W) hemisphere and a part of the other hemisphere on display, there is
a limitation to display a route. To avoid this, set chart center so that the whole eastern/
western hemisphere is not on the screen.
z Six routes, one active and five plan, can be shown simultaneously in the Voyage nav-
igation mode.
z If, in the radar mode, route monitoring is stopped, the alert 691 "RM Stop - Exceed
Max XTE", 692 "RM Stop - Disconnect Sensors", or 693 "RM Stop - Other Causes"
appears. If this occurs, switch to the Chart for Radar mode. The pop-up shown below
appears. Click the OK button. Find the reason why route monitoring was stopped and
then restart route monitoring.
z Route monitoring is stopped and an alert is displayed when the GPS position is lost.
Restore GPS position then restart route monitoring.
