4.1 Common setting
VECTOR REL/TRUE
The course and speed are indicated as vector after tracking is established.
Two types of display mode are available: relative display (REL) and true display (TRUE).
REL: This vector adds the course/speed of a target to the course/speed of own ship.
If the vector is directed towards own ship, possibility of collision exists.
It shows danger of collision at a glance and is useful to avoid collision.
TRUE: This vector shows the course/speed of a target only, regardless of own ship.
1 Press MENU key to display “Menu”.
Select [TARGET] => [VECT], and press ENT key after making selection.
2 In addition, there are [TIME], [TIME INCREMENT], [STAB INDICATOR] and [PATH INDICATOR]
setups.
[TIME]: It designates length of vector by time. When [TIME] is specified by 1 min, the vector is
displayed to the position that will be reached in 1 min by present target speed.
Selection values: OFF, 30sec, 1min, 3min, 6min, 12min, 30min, 60min
[TIME INCREMENT]: This vector displays the division number of time divider. When the setup
value is 2, vector is 1/2 and the parting line is displayed at a half-length
location of vector.
Selection values: OFF, 2, 3, 5, 10
Note: [TRUE / REL] and [TIME] can
be changed directly at the upper right
of the display, with trackball and ENT
key, without using menu.
