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
S
,
T
,
W
, or
X
(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
S
and
W
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.
