Getting StartedMap CursorUsing the Map CursorWorking from the Map Page is a simple process that centers around the use of the cursor. Controlledby the ARROW KEYPAD, the cursor is an important tool that can be used to pan to other map locations,mark and edit waypoints and routes, and review position data of on-screen map items and waypoints.To get a feel for using the Map Page and using the cursor, try the following exercise:1. Use the IN/OUT keys to set the map scale to the 50 nm setting. Your boat should be near the centerof the map, at the receiver’s last known position. (If your boat isn’t where it should be, make sure thatyou have initialized the receiver and acquired a position as described on pages 4-5.)2. Use the ARROW KEYPAD to move the cursor. Notice how another data field appears, showing thebearing and distance from your boat to the cursor, along with the latitude/longitude of the cursor.3. Press the QUIT key to remove the cursor and re-center your boat on the map display.As you become more familiar with the cursor, you’ll see that the map display actively scrolls or ‘pans’,letting you explore areas around the world and create waypoints and routes. Wherever you move thecursor, pressing the QUIT key centers the map on your current position.Now that you’ve seen how the Map Page can be used to monitor your present location, let’s take aminute to learn how to mark and store your present position as a “waypoint”. Since you’re in simula-tor mode, the present position displayed is the last position calculated by the receiver, which should bethe spot where you’ve initialized the unit. This also gives you an opportunity to see how the GPSMAP178/178C Sounder’s keypad and ENTER/MARK key are used for data entry and changing the waypointname and symbol.Current position Map ScaleMap CursorCursorCoordinatesDistance/Bearing
