[. . . ] This view also reports the current position, local time and date, and other numeric information. The current GPS Fix Type is reported as No Fix, 2D Fix, 3D Fix, or Enhanced. An Enhanced fix has been augmented using information from WAAS, EGNOS, or MSAS. HDOP (the Horizontal Dilution of Precision) is a GPS system parameter which depends on the current satellite configuration. HDOP is used to calculate the Estimated Position Error. 1 GPS Diagnostic View 2 4 3 1 Sky Chart 2 Satellite Being Used Current Latitude and Longitude Satellite Being Monitored 3 4 68 Sonar X-PressTM Menu The Sonar X-PressTM Menu provides access to the settings most frequently used. Press the MENU key once while in any of the Sonar Views to access the Sonar X-PressTM Menu. NOTE: Menu choices will vary depending on system settings such as whether the unit is set for Advanced User mode. NOTE: Quad Layout only appears in Side Beam View when the optional-purchase QuadraBeam PLUSTM transducer is attached and selected. Active Side Active Side allows you to select which side of a Combo View will be active; key presses will only affect the active side of the screen. When a menu is displayed, the non-active side of the screen will be grayed out; at any other time, a green arrow will point to the active side. Combo Views usually display sonar on the left, with charts or Bird's Eye usually on the right. The Active Side menu choice is only available when a Combo View is active. Use the RIGHT 4-WAY Cursor Control key to change which side is active. (Left, Right, Default = Left, or Sonar). Sonar X-PressTM Menu 69 Split Position Split Position allows you to adjust what percentage of the screen is taken up by the left side of any Combo View; each view may be adjusted independently; you must be in a specific view to adjust the screen size for that view. The number setting indicates the percentage taken up by the left side of the Combo View; selecting Left sets the left side of the screen to its smallest setting. The Split Position menu choice is only available when a Combo View is active. Use the RIGHT 4-WAY Cursor Control key to change the size of the left side of a Combo View. (Left, 30, 40, 50, 60, 70, Right, Default varies) Sensitivity at Medium To adjust the Sensitivity: 1. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Sensitivity setting. (Low = 1, High = 20, Default = 10) Sensitivity at Low Sensitivity Sensitivity controls how much detail is shown on the display. Increasing the sensitivity shows more sonar returns from small baitfish and suspended debris in the water; however, the display may become too cluttered. When operating in very clear water or greater depths, increased sensitivity shows weaker returns that may be of interest. Decreasing the sensitivity eliminates the clutter from the display that is sometimes present in murky or muddy water. If Sensitivity is adjusted too low, the display may not show many sonar returns that could be fish. Sensitivity at High 70 Upper Range (Advanced: Sonar, Split Sonar and Active Sonar Side Views only) Lower Range Lower Range sets the deepest depth range that will be displayed. [. . . ] Tracks are a useful and quick method to see where you've been, and an easy guide to follow to get you back to the starting point. Generally, all GPS units have a limited number of Track Points that can be saved before the unit runs out of memory and begins erasing the first track points saved. Because of this, the user can adjust the Track Point Interval menu to increase the amount of time between when points are saved, and thus extend the distance covered by a track. Tracks can also be permanently saved to memory, and re-displayed at the user's option. [. . . ]
