Ship Position Box
The Ship Position Box displayed in the upper right hand portion of the screen displays the name, latitude, longitude, depth, horizontal range, error codes, bearing and other information for the ship. The entire list of parameters that may be displayed in the position box is given below. The user may set which if any parameters will be displayed in the position box using the INPUT -> Ship Settings menu option. In the Target Settings dialog box click the position box items tab and check the position box items that should be displayed. If the most recent ships position received was an error then a question mark will be displayed instead of the number of satellites used to determine the ships position.
The ship position box may be moved to a more convenient location by dragging the box with the mouse. The position box can be expanded by dragging the borders of the box.
The following table lists the text displayed in the ship position box and their descriptions:
