Display item Description
Parameter
setting area
by operation
mode
The setting contents that are displayed in this area vary according to the selected
operation mode. Set parameters in each operation mode.
Refer to "4.6.3 Setting all the parallel index lines concurrently (All mode)", "4.6.4
Setting parallel index lines individually (Individual mode)", "4.6.5 Displaying lines at
equal interval on the left and right sides of the own ship’s position (Track mode)" and
"4.6.6 Displaying two intersecting lines (Equiangular mode)".
Floating Move the centre of the parallel index line. Select the Floating mode from the list.
[Off]: Sets the starting point of the parallel index line to the CCRP position.
[Screen Fix]: Moves the centre of the parallel index line and fixes it on the screen.
[L/L Fix]: Moves the centre of the parallel index line and fixes it based on the latitude
and longitude. (Connection of a navigation unit is required.)
Heading Link
(Heading link
setting)
Set whether the parallel index line is linked to the ship’s heading.
When this item is checked, the parallel index line is linked to the ship’s heading.
When this item is unchecked, the parallel index line is not linked to the ship’s
heading.
Different values can be set for the angle of the parallel index lines when this item is
checked and the angle of the parallel index lines when the item is unchecked.
Reference
Bearing
(Reference
bearing
selection)
Set a reference bearing of the bearing value display of the parallel index line.
This item is not displayed when the mode is [Equiangular].
[True]: Displays the bearing value in true bearing (based on the North).
[HL]: Displays the bearing value in the heading line reference.
Index Line 1 to Index Line 8: Displays the bearing value by using the Index Line as
the reference. (Only when the operation mode is [Individual])
Group 1 to Group 4: Displays the bearing value by using the Group as the
reference. (Only when the operation mode is [Track])
Switching the Floating mode
When [Screen Fix] or [L/L Fix] is selected in switching the Floating mode, the cursor mode changes.
Memo
When the operation mode is [All] and the reference point that is set in [L/L Fix] moves to the
position outside of the PPI circle, the floating mode is set to Off and the own ship’s position
becomes the reference point.
• When the screen is clicked on, the fixed position or the coordinates on the screen are
determined, and the cursor is changed to the normal cursor.
• When [Screen Fix] or [L/L Fix] is re-selected after the determination, the cursor changes to the
centre selection cursor for parallel index lines.
