Zooming, Panning and Pointing
There are three main actions you can perform on the Map Page: zooming, panning, and pointing.
The map display has 24 map scales (from 120 feet to 800 miles) which are selected by pressing
the IN and OUT zoom keys. The current map scale is indicated in the bottom left corner of the
map display.
To change the map scale:
1. Press the IN zoom key to see a smaller area with more detail.
2. Press the OUT zoom key to see a larger area with less detail.
When zoomed in to smaller map areas, ‘overzoom’ appears directly below the map scale. This
indicates the current scale exceeds the optimum resolution of available map detail. Extra caution should
be used in ‘overzoom’ since some detail, such as roads, are drawn using widely spaced points and the
actual layout of these details may differ from the map presentation.
Panning allows you to move the map in order to view areas beyond the current map area.
This provides a ‘look ahead’ capability which is particularly useful with smaller map areas.
To pan, use the ROCKER KEYPAD to move the map in any direction, including diagonally.
Once you are fi nished with panning, you can quickly remove the panning arrow and re-center
the map on your present position by pressing the QUIT key.
As you begin to pan the map, a pointer appears. This map pointer will serve as a target marker
for the map. If you change the scale, the map is redrawn with the pointer at the center. When the
pointer is placed on an object, the name of that object will be highlighted. (If the name wasn’t originally
displayed, it will appear when the pointer is placed on the object.) This feature applies to everything
displayed on the map except route lines and track log data. When a waypoint name is highlighted, you
can review information about the waypoint, list waypoint options, or execute a ‘Route to It’ directly
from the Map Page.
