15Zooming, Panning and PointingThere 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 pressingthe IN and OUT zoom keys. The current map scale is indicated in the bottom left corner of themap 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. Thisindicates the current scale exceeds the optimum resolution of available map detail. Extra caution shouldbe used in ‘overzoom’ since some detail, such as roads, are drawn using widely spaced points and theactual 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 finished with panning, you can quickly remove the panning arrow and re-centerthe 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 markerfor the map. If you change the scale, the map is redrawn with the pointer at the center. When thepointer is placed on an object, the name of that object will be highlighted. (If the name wasn’t originallydisplayed, it will appear when the pointer is placed on the object.) This feature applies to everythingdisplayed on the map except route lines and track log data. When a waypoint name is highlighted, youcan review information about the waypoint, list waypoint options, or execute a ‘Route to It’ directlyfrom the Map Page.ReferenceThe Map PageThe Map Page showing the panning arrow and ahighlighted map feature or point of interest.The Information Page for the park highlighted in thescreen above.
