2.16 Off-Centering
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 not available on ranges higher than 72 nm or in the true motion mode.
Note 1:
If the position of the CCRP results in a part of the bearing scale not being distinguishable, that part of the
bearing scale is indicated with appropriate reduced detail.
Note 2
: When the reference point is set for "conning position (CCRP) and the position of the antenna is more than
75% of the effective radius, offcenter is not cancelled on short ranges.
To off-center the radar picture, do the following:
From the control unit w/keyboard
1. Use the trackball to place the cursor at a position where you
wish to move the sweep origin.
2. Push
the
OFF CENTER
key. The sweep origin is off-
centered to the cursor position.
3. To cancel off-centering, push the
OFF CENTER
key again.
By trackball
1. With the cursor inside the effective display area, spin the
scrollwheel to display "TM Reset/Info/Ship Offcenter" in the
guidance area then push the scrollwheel or the right button.
2. Use the trackball to place the cursor where you want to locate
the screen center.
3. Push the right button to off center the sweep origin.
4. To cancel the off-center function, show "TM Reset/Info/Ship Offcenter" in the guidance area then push the right
button.
