8. Right-click the Trial title bar, select [Trial Mode] then choose a trial mode, [Static]
or [Dynamic].
9. Click the Trial ON/OFF indication to show [ON].

11. Click the Trial speed indication. spin the scrollwheel or use the Control Unit to set
the trial speed.
12. Click the [DELAY] indication. Spin the scrollwheel to set the amount of 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 left button to set.
The time indication depends on trial mode:
Dynamic mode: The position of your ship and TTs is updated and displayed every 30
seconds.
Static mode: The position of your ship and TTs 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 indication. Put the cursor
in the Trial time indication 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 maneuver.
When the cursor is removed from the box the original positions of your ship and TTs
are restored. If a maneuver 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 position on the display. If any TT 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 tri-
al speed, course or delay time to obtain a safe maneuver.
Terminating a trial maneuver
The termination depends on the trial mode as follows:
Dynamic mode: The trial is terminated when 60 minutes is shown in the Trial time in-
dication.
Static mode: The trial is terminated when you terminate the trial maneuver manually.
To terminate the trial maneuver manually, click the Trial ON/OFF indication to show
[Off].
