2.20 How to Off-center the Display
Own ship position, or sweep origin, can be displaced to expand the view field without
switching to a larger range scale. The sweep origin can be off-centered to the cursor
position, but not more than 75% of the range in use; if the cursor is set beyond 75%
of the range scale, the sweep origin will be off-centered to the point of 75% of the limit.
This feature is available on the ranges between 0.125 and 48 NM and any presenta-
tion mode other than true motion.
If the position of the CCRP results in a part of the bearing scale not being distinguish-
able, that part of the bearing scale is indicated with appropriate reduced detail.
How to off-center the display from the Control Unit
1. Put the cursor on the position within the display area where you want to move the
sweep origin.
2. Press the OFF CENTER key to move the sweep origin to the cursor position.
To cancel off-centering, press the OFF CENTER key again.
How to off-center the display from the context-sensitive menu
1. Put the cursor where you want to off-center the display then right click to show the
context-sensitive menu.
2. Select [Off Center].
3. Push the left button. Then, the sweep origin is off-centered to the cursor position.
To cancel the off-center display, put the cursor on the sweep origin and right-click.
If you cannot cancel off-center…
When the conditions shown below are met, offcenter cannot be cancelled. This is be-
cause the radar antenna position is located at a position greater than 75% of the ef-
fective radar display.
• Own ship marker is large.
• The distance between the antenna position and the conning position is large.
• Short-distance display range.
To cancel the off-center in the above-mentioned conditions, first select a larger range,
then cancel the off-center.
