Reference Manual Part 2

139 Chapter 11: Radar
If heading and position data become unavailable when true motion
is selected: a warning message is shown; the display reverts to rel-
ative motion; the status bar indicates that True Motion is selected
but suspended by showing it in parentheses (TM).
It is not possible to select True Motion when the orientation is set to
Head Up.
To set the motion mode
1. Press the PRESENTATION softkey.
2. Press RADAR MODE AND ORIENTATION.
3. Toggle between True and Relative Motion on the MOTION
MODE key.
To change the vessel offset
1. Press the PRESENTATION softkey.
2. Press RADAR MODE & ORIENTATION.
3. Toggle to your desired offset using the VESSEL OFFSET
softkey.
Changing the bearing mode for EBLs
The default bearing mode for EBLs is relative to your vessel’s
heading. If heading data is available, you can set the bearing mode
to be relative (REL) or magnetic/true (M/T).
When M/T is selected, the EBL bearings will be expressed as either
true or magnetic, depending on the equipment connected. The cur-
rent EBL bearing is given on the EBL label and on the ADJUST
EBL softkey label.
To change the EBL reference
1. Press the PRESENTATION softkey.
2. Toggle between M/T and REL on the EBL REFERENCE key.
Dual range
The G-Series system allows you to view either a short- or a long-
range image in separate radar windows. To allow this, dual range
must be enabled in the Radar Setup Menu (see Radar setup on
page 128).
To set the range
1. Press the PRESENTATION softkey.
2. Press RADAR MODE & ORIENTATION.
3. Toggle between LONG and SHORT on the DUAL RANGE
softkey.
The default setting is long, which provides a standard scanner
range. The short setting provides a maximum range of six or twelve
nautical miles.
Note: If chart-radar sync is turned on in the chart application, you
cannot enable dual range in the radar application. If dual
range is on, you cannot turn on chart-radar synchronization.
