How to Use the Cursor

The cursor functions to select position for marks and waypoints, find position of an ob-
ject, etc. You can select the cursor shape from crossing line and cross-hair.
To use the cursor, do the following:
1. Press the CURSOR ON/OFF key to turn on the cursor. Each press of this key
turns the cursor on and off.
Note: You can change the shape or color for the cursor in the [DISPLAY FOR-
MAT] - [CURSOR SHAPE] or [CURSOR COLOR] menus (see page 9-13).
2. Do one of the following to move the cursor.
• Rotate the trackball. The cursor moves in the direction of trackball rotation.
• Press , , , or  (CursorPad). The cursor moves in the direction of the ar-
row operated. You can hold down an arrow pad to move the cursor faster. To
move the cursor at a slant angle, press the appropriate arrow pads together. For
example, to move the cursor in the left-up direction (approx. 315°), press  and
 together.
The procedures in this manual, for sake of brevity, replace the "rotate" and "press"
actions with "move the cursor".
When the cursor reaches an edge of the screen, the display is scrolled in the op-
posite direction. When the cursor is turned on, the cursor position is displayed in
the NAV information box when [CURSOR LATITUDE, LONGITUDE] is set as the
navigation/destination information (see section 1.4.4).
3. To put the cursor at the center of the screen, press the CENTER key.
2.3 How to Change the Chart Scale (Zoom In, Zoom
Out)
It can be useful to change the chart scale to
• show destination on the display (when it is currently off the screen)
• find how close you are to your destination
• view ship's tracks around a fishing ground
Press the ZOOM IN key to increase the chart scale, or the ZOOM OUT key to de-
crease the chart scale.
When the cursor is OFF: The range scale is enlarged or shrunk with own ship position
as center. When own ship mark is not displayed on the screen, the range scale is en-
larged or shrunk with the middle of the screen as center.
