Operation of Trial Maneuvering Function 
 
 Procedures   1  Open the Trial Maneuver menu by performing the following menu 
operation. 
 
       TT 
 → Trial Maneuver 
 
2  Left-click the item button of    Trial Function . 
 
The Trial Function will be set to on or off. 
 
  On      : The trial maneuvering function is turned on. 
  Off      : The trial maneuvering function is turned off. 
 
When Trial Function is set to on, the character " T " indicating trial maneuvering blinks in 
the own ship display field of the radar display.   
 
3  Set values for Course by turning the [EBL] dial, and for Speed by turning 
the [VRM] dial. 
 
4  Set other characteristics. 
 
  Vector Time    : Vector time (1 to 60 min) 
  Time to Maneuver    : Time until trial maneuvering is started (0 to 30 min) 
  Own Ship Dynamic Trait>     : Dynamic trait of the own ship 
→    Reach    : Range from when steered to when the ship 
  beings to turn (0 to 2000 m) 
→    Turn Radius    : Turning radius (0.10 to 2.00 nm) 
→ Acceleration   : Acceleration (0.0 to 100 knots/min) 
→ Deceleration   : Deceleration (0.0 to 100 knots/min) 
 
For inputs to the value input screen, refer to Section “3.3.6 Operation on Numeric Value, 
Latitude / Longitude and Character Input menu”. 
 
Dangerous target symbols are displayed in red and safe target symbols in white. 
 
*    Vector Time is valid only when Trial Function is set to on. If it is off, the vector time before trial 
maneuvering is displayed. 
  Time until the start of trial maneuvering is counted down directly after the input. 
  The acceleration and deceleration are influenced depending on the relationship between the current speed 
and the input speed for trial maneuvering. 
  If 0.0 kn/min is set for   Acceleration   when the speed for trial maneuvering is faster than the current 
speed, or for  Deceleration  when the speed for trial maneuvering is slower than the current speed, the 
system performs simulation on the assumption that the speed is changed directly after the time set for 
  Time to Maneuver . 
 
 
 Cancellation   1  Open the Trial Maneuver menu by performing the following menu 
operation.
