[. . . ] Operations Manual 531369-1_A Matrix 12 Matrix 10 Matrix 17 Matrix 20 Matrix 27 Matrix 37 Thank You! Thank you for choosing Humminbird®, America's #1 name in fishfinders. Humminbird® has built its reputation by designing and manufacturing top-quality, thoroughly reliable marine equipment. Your Humminbird® is designed for trouble-free use in even the harshest marine environment. In the unlikely event that your Humminbird® does require repairs, we offer an exclusive Service Policy - free of charge during the first year after purchase, and available at a reasonable rate after the one-year period. [. . . ] 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. 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 790/990/1490 feet or 0 to 257/327/497 meters [International Models Only], Default = 0) NOTE: Settings are dependent on the depth capability of your particular Fishing System model. Sensitivity at Low Sensitivity at Medium Sensitivity at High 23 24 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. NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower Range regardless of the manual settings entered. 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. 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) To adjust the Lower Range: 1. Highlight Lower Range on the Sonar X-PressTM Menu. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Lower Range setting. (AUTO, 10 to 800/1000/1500 feet, 3 to 260/330/500 meters [International Models Only], Default = AUTO) NOTE: Settings are dependent on the depth capability of your particular Fishing System model. Bottom View Bottom View selects the method used to represent bottom and structure on the display. [. . . ] When an accessory is connected to the Matrix Fishing System, additional menus and readouts are added automatically to the Main Menu System. Accessories available today that are supported by your Fishing System include: Temperature/Speed: purchase and plug in the Temperature/Speed accessory to your Matrix control head to get real time speed and temperature readouts, as well as a valuable Triplog function. NOTE: If an external Temperature/Speed (TS-W) or Temperature (TG-W) accessory is connected AND a transducer with temperature built in is connected at the same time, the TS-W or TG-W accessory will override the temperature which is built in to the transducer. Isolation Turn off any nearby electronic devices to see if the problem goes away, then turn them on one at a time to see if the noise re-appears. To determine whether the boat's engine is the source of the noise, increase the RPMs while the boat is in neutral and stationary to see if the noise increases proportionately; if noise appears when you rev the engine, the problem could be the spark plugs, alternator, or tachometer wiring. Replace the spark plugs with resistor plugs, install an alternator filter, or route the control head power and transducer cables away from the engine wiring. [. . . ]
