3.4 BASIC OPERATIONS
……Move Cross Cursor Mark [ + ] by Trackball ………………………
The cross cursor mark [ + ] is used for position designation and other purposes in various operating
procedures. The cross cursor mark [ + ] moves in coupling with the trackball. If the trackball is rotated
up and down or left and right, the cross cursor mark follows the move of the trackball. The distance and
bearing between own ship and the cross cursor mark [ + ] are indicated on the upper right of the radar
display. Before operating other controls and switches, the operator must be familiar with manipulation
of the trackball and the move of the cross cursor mark. When rotating the trackball, the cross cursor
mark [ + ] will not move if the palm is apart from the hand sensor section. Approach the palm to the
hand sensor section and operate the trackball.
