Radar Overlay
• Position and heading data are provided so that vessel position and orienta-
tion can be determined.
• The vessel must be displayed on screen.
• The chartplotter must be in North Up or Course Up mode (see Section 7.5).
• The chartplotter range must be between 1/4nm and 48nm (equivalent to a
radar range of 1/8nm to 24nm).
• Custom range scales are disabled on the radar.
• The radar must be transmitting.
To ensure the vessel remains on the screen, you could use Find Ship (see Using
FIND SHIP on page 3-29) to home the cursor onto the vessel.
When Radar/Chart overlay is switched on, the status bar indicates OVL. If the
option is switched on but the overlay is not visible (because one of the above
criteria has failed), the status bar indication changes to (OVL).
When Radar/Chart overlay is switched on the soft key MORE... provides
access to the SCREEN soft key and to the radar controls TARGETS and MARPA.
The radar GAIN control is also active in overlay mode.
Radar/Chart overlay is displayed at the current chart range. You should be
aware that if radar is shown on any other display, its range will match that
displayed on Radar/Chart overlay. Conversely, if you change the radar range
on any display, the Radar/Chart overlay image will change to the new radar
range.
➤ To select radar/chart overlay:
1. Press the DISPLAY key to show the DISPLAY pop-up, then if necessary
press again to select Chart mode.
2. Press the OVERLAY OFF ON soft key to toggle the option on.
The two highest intensity radar returns are displayed in purple, over the chart
image. The radar image is translucent, so that chart text, contours and outlines
are visible beneath the radar targets.
