Garmin GPS 90, Руководство пользователя и справочник, Страница: 46 / 92

There are three main functions you can perform from
the Map page— zooming, pointing and panning. Each of
these functions has its own ‘field’, which may be selected
and activated for use.
Whenever the Map Page first appears, the zoom fie l d
(at the top left) is always selected. The Map Page has 12
map scales which are selected through the zoom function
field.
To select a zoom scale:
1. Press
L
or
R
to highlight the zoom field.
2. Press the
E
key to begin range selection.
3. Use the
U
or
D
keys to scroll through and find the
desired range scale.
4. Press
E
to confirm your selection.
The second function field on the Map page is the pan
field, located at the top right of the screen. The pan func-
tion allows you to move the map with the four arrow keys
to view areas outside the current map
To activate the pan function:
1. From the zoom field, use the
R
key to highlight the pan field.
2. Press the
E
key to activate the pan function.
3. Use the arrow keys to move the map in any direction.
As you begin to move the map, a crosshair will appear.
This crosshair will now serve as a target marker for the
moving map. The distance and bearing to destination (at
the bottom of the page) will now be replaced by the dis-
tance and bearing from your present position to the target
crosshair.
As you pan around the moving map display, you’ll
notice that the target crosshair will ‘snap’ to on-scre e n
waypoints and highlight the waypoint name. Once a way-
point name is highlighted, you can review its waypoint
d e finition page or execute a GOTO function right fro m
the Map page.
