8. Use the scrollwheel to select delay time at DELAY. This is the time after which own ship takes a new situation,
not the time the simulation begins. Change the delay time according to own ship loading condition, etc. Spin the
scrollwheel to select numeric; push the scrollwheel to set.
9. Use the trackball to select the course-setting box. Use the scrollwheel to set the course: Spin the scrollwheel to
select location; push the scrollwheel to set.
10. Use the trackball to select the speed-setting box. Use the scrollwheel to set the speed: Spin the scrollwheel to
select location; push the scrollwheel to set.
Note: Course and speed may also be set with the EBL and VRM, respectively. Put the cursor in any one of the
four trial maneuver related boxes and operate applicable control.
11. Select TRIAL SET. Push the left button or the scrollwheel. The TRIAL box shows "TRAIL 00:00" (00:00 is trial
maneuver time).
The time indication depends on trial mode:
Dynamic mode: The position of your ship and tracked targets is updated and displayed every 30 seconds.
Static mode: The position of your ship and tracked targets when set course and speed are reached are displayed.
The progress time until the position is reached is indicated on the display. The trial time can be changed from the
Trial Time box. Put the cursor in the Trial Time box and roll the scrollwheel. The position of targets at the end of
selected time is shown. Increase or decrease the time to get a safe manuever. When the cursor is removed from the
box the original positions of your ship and tracked targets are restored. If a manuever is unsafe, change speed,
course and delay until it is safe.
The trial maneuver takes place with the letter "T" displayed at the bottom of the screen. The time appears at the top
right side of the display. If any tracked target is predicted to be on a collision course with own ship (that is, the
target ship comes within preset CPA/TCPA limits), the target plotting symbol flashes. If this happens, change own
ship's trial speed, course or delay time to obtain a safe maneuver.
