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.
