[. . . ] Highlight Chart Speed on the Sonar X-PressTM menu. 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 = 4) Upper Range sets the shallowest depth range that will be displayed on the Sonar and Big Digits Views. The Upper Range menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). 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. To adjust the Upper Range: 1. Make sure you are in Advanced Mode, then highlight Upper Range on the Sonar X-PressTM menu. 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) Bottom View Bottom View selects the method used to represent bottom and structure on the display. Structure ID® represents weak returns in blue and strong returns in red. WhiteLine® highlights the strongest sonar returns in white resulting in a distinctive outline. This has the benefit of clearly defining the bottom on the display. (See Bottom Presentation for more information. ) To adjust the Bottom View: 1. Highlight Bottom View on the Sonar X-PressTM menu. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Bottom View setting. (Structure ID, WhiteLine, Default = Structure ID) Lower Range Lower Range sets the deepest depth range that will be displayed. 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. To adjust the Lower Range: 1. Highlight Lower Range on the Sonar X-PressTM menu. [. . . ] · Replace the transducer with a known good transducer if available and power up the control head again. · Check the transducer cable and connector. Replace the transducer if the cable is damaged or corroded. There are no fish detected, even when you know they are in the water under the boat, or sonar readings seem weak or faulty. Sonar readings may be affected if the transducer is not positioned correctly (i. e. mounted at an angle, not straight down), or there is some kind of mechanical interference, either because it is mounted inside a hull that is too thick for proper sonar transmission, the bond between the transducer and the hull is not airtight, or because the transducer is dirty.
