User manual HUMMINBIRD N825

[. . . ] Overview How the NS25 Works Congratulations on your purchase of the Hummingbird NS25. The NS25 uses GPS and sonar capability to determine your position, display it on a map, and provide detailed underwater information. The NS25 consists of four primary components; the control head, GPS receiver (SAT MAX), card reader and transducer. The control head contains the user controls and display. [. . . ] Buttons are used for navigation options and entering data. See the following illustration and descriptive table listing buttons and functionality. Power/Light: Turns on the unit initially. Pressing and holding the Power button for three seconds turns unit off. Pressing it briefly while the unit is operating displays the Adjust Backlight menu. View: Selects the six different views: North-Up, Course-Up, Combo, Sonar, Numeric, and System Status. Cursor: Used to move the cursor (cross-hair line visible in graphics area), pan the map, and select waypoints. Used to make selections when menus are displayed. Zoom +/-: Controls the range at which the map is drawn on the screen. The "+" button increases the map range. The "-" button decreases the map range. Menu: Displays the Main Menu Bar list and toggles through each of the five menu options. Go To: Initiates navigation to a destination. Info: Displays detailed information for highlighted waypoints. Controls information display settings for graphical and numeric information. P-Star: Instantly stores the location of your present position. If the cursor is on-screen, the cursor position is stored. Clear: Exits any current operation, clears screen of bird-notes, and mutes an active alarm. When no action has been initiated a menu provides options to clear course history, current route, and temporary waypoints. Views Six views in the NS25 display your position, maps, numeric information boxes, and sonar information. Press the VIEW button to toggle between each of the views in the sequence: North-Up, CourseUp, Combo, Sonar, Numeric, and System Status. This toggle function is a continuous loop, so if you miss a view, keep pressing the VIEW button to return to the view you would like to display. On views displaying a map, your present position is indicated by a square if you are stationary, or a boat icon if you are moving. The graphic course indicator always shows your course relative to north. A course history trail tracks where you have traveled. [. . . ] If "NONE" displays in the field (indicating that it is not receiving), try toggling between both baud rates and check connections. Refer to your DGPS manual for further instructions.
