    INSTALLATION PREPARATION ALTERNATE TRANSDUCERS AND MOUNTING METHODS Inside the hull installations require no holes be drilled into the boat and through experimentation, high-speed operation comparable to transom mounting can be achieved. Two part, slow cure epoxy is required to glue the transducer in place.

  • Page 7: Transducer Exchange

    INSTALLATION PREPARATION TRANSDUCER EXCHANGE Thru-hull mounting may require the use of a fairing block to level the transducer with the waterline. Also, since special tools and knowledge may be required to perform this type of installation it is best to refer to a qualified marine technician.

  • Page 8: Using The 350Tx

    USING THE 350TX HOW SONAR WORKS HOW SONAR WORKS Your Humminbird unit uses sonar to locate and define underwater objects, define the bottom terrain, as well as determine distance. Sonar technology is based on sound waves. Your Humminbird unit sends out a sound wave signal.

  • Page 9: Simulator Operation

    USING THE 350TX SIMULATOR OPERATION Actual depth capability depends on factors such as bottom hardness, water conditions, and transducer installation. Units will typically read to deeper depths in fresh water than in salt water. SIMULATOR OPERATION The 350TX contains a simulator that allows you to use the unit as if you are on the water.

  • Page 10: What You See On Screen

    USING THE 350TX WHAT YOU SEE ON-SCREEN If you are using the 350TX in Simulator when no transducer is connected, any selected options are lost when the unit is powered off. The 350TX will return to Factory Settings, or options selected when last used with a transducer, if no transducer is connected.
  • Page 11 USING THE 350TX WHAT YOU SEE ON-SCREEN Bottom Depiction Zero Line When in Auto mode, the horizontal line at the top of the screen is the “zero line,” representing the surface of the water. Occasionally there is a gap in this line. This gap indicates the unit is updating the display even if the bottom is not visible on- screen, or if the bottom information...
  • Page 12 USING THE 350TX WHAT YOU SEE ON SCREEN Structure. Structure is defined as any object physically attached to the bottom. The sonar configuration of the 350TX is optimized to give the most accurate depiction of bottom structure possible. Grass, trees, stumps, wrecks or other debris are accurately displayed, however the depiction of these objects varies with boat speed and direction.

    USING THE 350TX CONTROL FUNCTIONS that a small fish close to the boat does Fish in Left Beam Fish in Right Beam not appear as a large fish symbol. ID + adds an additional piece of information to help the user locate fish. On selected fish symbols, the digital depth of the designated fish is drawn to help locate the fish vertically.
  • Page 14 USING THE 350TX CONTROL FUNCTIONS Power. The Power button powers the 350TX up for normal operation. When the unit is on, POWER turns the unit off. POWER can also be used to go directly into Simulator mode. To enter simulator, with the unit powered off, press and hold POWER for several seconds until a continuous chirp is heard.
  • Page 15 USING THE 350TX CONTROL FUNCTIONS corresponding ARROW button has no function. Pressing that button will result in no adjustment and the “error” audible will be heard. A solid ARROW symbol means the corresponding ARROW button can be used to affect the menu adjustment. The ARROW buttons often can be used when no menu is on-screen.

  • Page 16: Menu Functions

    USING THE 350TX MENU FUNCTIONS Menu Functions Sensitivity. The Sensitivity function controls the sensitivity of the sonar receiver. The 350TX automatically adjusts the level of receiver sensitivity based on a number of factors including the depth of the water and the level of noise present.
  • Page 17 USING THE 350TX MENU FUNCTIONS After an adjustment is made, the menu disappears and the new sensitivity setting is in affect. If additional time is needed to study a menu, press and hold the MENU button and the menu will remain on-screen indefinitely. If you need to make an additional adjustment, press the UP ARROW or DOWN ARROW button.
  • Page 18 USING THE 350TX MENU FUNCTIONS Using manual Depth Range control, you can view sonar information from the area near the surface in great detail. To return to automatic Depth Range control, press the MENU button until the Depth Range menu appears on-screen and use the UP ARROW to select AUTO.
  • Page 19 USING THE 350TX MENU FUNCTIONS which the Zoom range is constantly adjusted to show the bottom, or manually, in which the user controls the location of the Zoom range. Automatic Zoom is especially helpful when looking for structure or bottom detail. The Automatic Zoom keeps the bottom in view even in quickly changing terrain, but is most useful in flatter areas without considerable depth variation.
  • Page 20 USING THE 350TX MENU FUNCTIONS Fish Alarm. The Fish Alarm alerts you to the presence of fish, or other targets not connected to the bottom. The Fish Alarm three different settings that correspond to the three different size fish symbols shown on-screen. The default setting is “OFF.”...
  • Page 21 USING THE 350TX MENU FUNCTIONS Reset to zero time traveled, distance and average speed.The time, speed and distance calculations are useful for tracking your progress on a trip. The input voltage is useful for determining the condition of the charging system of the boat.
  • Page 22 USING THE 350TX MENU FUNCTIONS contrast can be achieved. Use the ARROW buttons to highlight the desired selection. The 350TX will remember the contrast setting if connected to a transducer, otherwise it resets to the factory setting when the unit is powered off.
  • Page 23 USING THE 350TX MENU FUNCTIONS determine the texture and relative Bottom Black View hardness of the bottom. Selecting Bottom Black “ON” causes the unit to blacken in the display below the bottom. This gives the user easiest recognition of the bottom location, even from a great distance.
  • Page 24 USING THE 350TX MENU FUNCTIONS Increasing the value to a number greater than zero shows more fish symbols on-screen. In this case smaller sonar returns will be depicted as fish symbols. This is useful for identifying many smaller sonar returns (such as baitfish) as fish symbols.
  • Page 25 USING THE 350TX MENU FUNCTIONS Often a transducer switch is used to connect two tri-beams transducers, or a tri- beam and a wide side to the 350TX. In AUTO the 350TX identifies the transducer as the switch is changed. Only if the transducer is faulty do you need to manually identify the transducer in the menu.
  • Page 26 ADVANCED FEATURES USING DIAGNOSTIC Speed Offset. The Speed Offset option allows the user to compensate for differences in hull design, and its effect on the accuracy of the speed measurement. If there is a discrepancy between the indicated speed and another speed measurement device on the boat, the speed measurement can be varied to improve accuracy.

The side-looking elements can be used independently, or together to locate targets near the surface of the water on either side of your boat. The Wide Side transducer can be connected directly to the 350TX or used in conjunction with the standard transducer through a transducer switch.

  • Page 30: Maintenance

    Repairs should be performed only by authorized Humminbird technicians. Many requests for repair received by Humminbird involve units that do not actually need repair. These units are returned “no problem found.” If you have a problem with your 350TX, use the following troubleshooting guide before sending your unit in for repair.
  • Page 31 MAINTENANCE TROUBLESHOOTING 1. Nothing happens when I turn the unit on. Check the power cable connection at both ends. Be sure the cable is connected correctly to a reliable power source—red lead to positive, black lead to negative or ground. Ensure the power available at the mount is between 10 and 20 VDC. If the unit is wired through a fuse panel, ensure the panel is powered.
  • Page 32 MAINTENANCE TROUBLESHOOTING If you are using a transducer switch to connect two transducers to the 350TX, ensure the switch is in the correct position to connect a transducer that is in water. (If a trolling motor transducer is selected and the trolling motor is out of water, no sonar information appears.) If none of the above solve the problem, inspect the transducer cable from end to end for breaks, kinks, or cuts in the outer casing of the cable.
