The Upper Range menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode) and can only be accessed from the Sonar, Split Sonar, Big Digits and Circular Flasher views. Upper Range is often used with Lower Range. For example, if you are only interested in the area between 20 and 50 feet deep, you should set the Upper Depth Range to 20 and the Lower Depth Range to 50. The Sonar View will then show the 30 foot area between 20 and 50, and will not show the surface or the bottom (assuming the bottom is deeper than 50 feet), and will show greater detail for that area between 20 and 50 feet. NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower Range regardless of the manual settings entered. To adjust the Upper Range: 1. Make sure you are in Advanced Mode, then highlight Upper Range on the Sonar X-PressTM Menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Upper Range setting. (0 to 990 feet or 0 to 327 meters [International Models only], Default = 0) 27 Lower Range Lower Range sets the deepest depth range that will be displayed. Automatic is the default setting. When in automatic mode, the lower range will be adjusted by the unit to follow the bottom. Selecting a specific setting locks the depth range into Manual mode. Use both Upper and Lower Range together to view a specific depth range manually when looking for fish or bottom structure. M will be displayed in the lower right corner of the screen when you start manually adjusting the Lower Range to indicate that you are in Manual mode. For example, if you are fishing in 60 feet of water but are only interested in the first 30 feet (surface to a depth of 30 feet) you should set the Lower Depth Range limit to 30. The display will show the 0 to 30 foot range, allowing you to see a more detailed view than you would see if the display went all the way to the bottom. NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower Range regardless of the manual settings entered. To adjust the Lower Range: 1. Highlight Lower Range on the Sonar X-PressTM Menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Lower Range setting. (AUTO, 10 to 1000 feet, 3 to 330 meters [International Models only], Default = AUTO) 28 531447-1_A_343c_Eng.qxd 11/11/2005 9:18 PM Page 34 Chart Speed Chart Speed determines the speed at which the sonar information moves across the display, and consequently the amount of detail shown. A faster speed shows more information and is preferred by most anglers; however, the sonar information moves across the display quickly. A slower speed keeps the information on the display longer, but the bottom and fish details become compressed and may be difficult to interpret. Regardless of the Chart Speed setting, the RTS® Window will update at the maximum rate possible for the depth conditions. Adjust Chart Speed to your personal preference. To adjust the Chart Speed: 1. Highlight Chart Speed on the Sonar X-PressTM Menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Chart Speed setting. (1-9, Ultra, where 1 = Slow, 9 = Fast, Ultra = Fastest, Default = 5) Zoom Level (Sonar Zoom View only) Zoom Level sets the magnification level for the Sonar Zoom View, and is only available on the X-PressTM Menu when the Sonar Zoom View is active. Use Zoom to increase the display resolution to separate sonar returns that are very close together. To adjust the Zoom Level: 1. Highlight Zoom Level on the Sonar X-PressTM Menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Zoom Level setting for the Sonar Zoom View. (2x, 4x, 6x, 8x, Default = 2x) NOTE: The Zoom Preview Box tracks the bottom and cannot be moved by the user. 29 Bottom Lock (Sonar Zoom View only) Bottom Lock changes the mode of the Zoomed view in the Sonar Zoom View. Bottom Lock continuously graphs the bottom at a constant point on the display regardless of changes in depth. This "flattens" out the bottom contour, but is effective at showing fish on or near the bottom. To turn on Bottom Lock: 1. In the Sonar Zoom View, highlight Bottom Lock on the Sonar X-Press™ Menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Bottom Lock setting to on. (Off, On, Default = Off) Bottom Range (Sonar Zoom View only, when Bottom Lock is On) Bottom Range allows you to control how much of the water column, measured up from the bottom, is shown in the Sonar Zoom View. Choose a small value to see low- lying bottom structure or details of the bottom return. Choose a larger value to see large structure in deeper water. It is possible to set the Bottom Range to be greater than the depth. In this case, you may see surface clutter in a wavy band that mirrors changes in the depth. To adjust the Bottom Range: 1. In the Sonar Zoom View, highlight Bottom Lock on the Sonar X-Press™ Menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys ...
