[. . . ] Press the MENU key once while in any of the Sonar Views to access the Sonar X-PressTM menu. NOTE: Upper Range only appears in Advanced User Mode when in Sonar or Big Digits View. NOTE: Zoom Level only appears in Sonar Zoom View. 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. Sonar X-PressTM Menu Sensitivity at Low Sensitivity at Medium Sensitivity at High To adjust the Sensitivity: 1. Use the LEFT or RIGHT 4-Way Cursor Control keys to increase or decrease the Sensitivity setting.

A faster speed shows more information in the Sonar View 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. 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. (See Bottom Presentation for more information. ) To adjust the Bottom View: 1. [. . . ] Reconnect if necessary, and power up the FishFinder again to see if this fixes the problem. · Replace the transducer with a known good transducer if available and power up the control head again. 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.
