[. . . ] · Course-Up: The direction of motion of the boat is shown at the top of the display. Objects ahead of the boat are drawn above the boat. When the boat is stationary, it is drawn as a circle. When the boat is in motion, it takes on a boat shape, pointed in the direction of motion (always Up in the Course-Up orientation). Viewing Cartography In the Chart and Combo Views, there are several cartography-related functions that you can access using various keys. Panning: Use the 4-WAY Cursor Control key to move the chart around on the display in the direction of the key being pressed. When you do this, a bull's eye cursor is drawn at the center of the screen and is linked to the boat by a gray line, even if the boat is off the screen. At the same time, a cursor dialog box is displayed at the top of the screen with the distance and bearing from the boat to the cursor position and the latitude/longitude coordinates of the cursor. When the cursor is active on the display, you can also use the 4-WAY Cursor Control key to move the cursor diagonally. Chart View with Cursor Present Viewing Cartography 74 Zooming: Press the Plus (+) key to Zoom In and the Minus (-) key to Zoom Out to see the cartography at different magnification levels. The zoom level is indicated on the left side of the display. If you zoom in beyond the available chart data, the display will go into Overzoom mode whereby the last available chart data is amplified to reflect the level selected. If you zoom in so far that no cartography is available, a lat/long grid will be drawn instead. Screen Snapshots and Recording Icons: When a waypoint is created while Screen Snapshot and Recording is active, the waypoint will appear as a snapshot icon or recording icon in chart views. See Views: Snapshot and Recording View for more information. Chart Info: Press the INFO key to get detailed information about the chart. If the cursor is active, you will see information about the chart objects located near the cursor. If the cursor is not active, the Chart Info submenu will appear. Use the 4-WAY Cursor Control key to select the Nearest Port, the Nearest Tide Station, or the Nearest Current Station and see information about any of these objects. NOTE: The built-in UniMapTM does not contain any Port, Tide, or Current information. This information is only available from optionalpurchase MMC/SD cards. Nearest Port: The position and services information for the nearest port to your present position will be displayed. Press the EXIT key to remove the information box and the cursor bull's eye will be centered over the port position. The cursor information boxes will indicate the distance and bearing to the port from your present position. Nearest Tide Station: Tide information for the nearest tide station to your present position will be displayed. This includes the position of the station and the times of the high and low tides for today's date. [. . . ] Trolling Grid A Humminbird® feature that displays a precise reference grid around a waypoint. This grid is used as a guide pattern for trolling around a specific area to assure a more efficient and complete coverage of that area. UTC (Universal Time Constant) UTC is the "standard time" used in navigation and is the local time in Greenwich England. (UTC is equivalent to Greenwich Mean Time (GMT)). [. . . ]
