JRC JMR-7230-S Instruction Manual page 132

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].
To finish trial operation:
1
Clear the [Trial Function] checkbox.
