5.10 Showing and hiding waypoints
This option lets you specify which waypoints are displayed on the
screen. You can show all waypoints, or display them by symbol or
group.
The latter options are useful if you have many waypoints placed in
a small area, which can clutter the chart.
Note: The show/hide status of a waypoint is a local setting and will
therefore only affect the individual display on which you are
working.
To show or hide waypoints by group or symbol
1. Press the PRESENTATION softkey.
2. Press SHOW/HIDE WAYPOINTS.
3. Toggle between SYM and GROUP on the SHOW BY softkey.
4. Select the relevant group and toggle its setting to SHOW or
HIDE on the ON CHART softkey.
To show or hide waypoint names
1. Press the PRESENTATION softkey.
2. Press SHOW/HIDE WAYPOINTS.
3. Toggle to the required setting with the WAYPOINT NAME
softkey.
To show or hide waypoint index numbers
1. Press the ROUTES softkey.
2. Press SHOW/HIDE ROUTES.
3. Toggle settings with the WAYPOINT INDEX softkey.
5.11 Chart layers
You can overlay data onto a chart window to give greater depth of
information. You can overlay radar, AIS or range rings.
Radar overlay
Overlaying the chart image with radar data allows for better distinc-
tion between stationary and moving objects. For best results,
switch on radar-chart synchronization.
You can customize the opacity setting for the overlaid image by
twisting the rotary controller.
If you have two radar scanners installed, select which one you want
to use for the overlay in the setup menu.
Note: A radar image cannot be overlaid onto a chart window if
dual-range is enabled in the radar application.
To switch radar overlay on or off
1. Press the PRESENTATION softkey.
2. Press CHART LAYERS.
3. Toggle radar overlay on or off with the RADAR OVERLAY
softkey.
To access radar and navigation options from the chart
application
1. Press OK twice.
2. Select RADAR options or NAVIGATION OPTIONS with the
appropriate softkey.
