These accessories are designed with the same high standards. The Humminbird Accessory catalog included with your unit contains descriptions of the many accessories available and ordering information.

  • Page 5: Installation Preparation

    INSTALLATION PREPARATION The transducer converts electrical energy from the transmitter into mechanical pulses or sound waves. The transducer also receives the reflected sound waves and converts them back into electrical signals for display on the control head. It should be installed in contact with the surface of the water in an area that has smooth water flow - usually on the transom of the boat.

  • Page 6: Alternative Transducers And Mounting Methods

    INSTALLATION PREPARATION ALTERNATE TRANSDUCERS AND MOUNTING METHODS Inside the hull installations require no holes to 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: Beginning Installation

    INSTALLATION PREPARATION BEGINNING INSTALLATION Now that you have determined the transducer mounting method, you can begin installation of the 405SX. The fold out installation guide included provides detailed step by step instructions for installation of the control head and transducer. For transom mount transducer installations, you will need the mounting template at the back of this manual.

    USING THE 405SX 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.

    USING THE 405SX WHAT YOU SEE ON-SCREEN Temperature/Speed. The initial screen layout takes one of two basic forms depending on whether the optional Temp/Speed accessory is installed. Figure A shows the default view when the Temp/Speed accessory is installed. Figure B shows the default view when the Temp/Speed accessory is not installed.
  • Page 11 USING THE 405SX WHAT YOU SEE ON-SCREEN This range is selected so the bottom representation is typically shown about down the display. Bottom. The graphic depiction of the bottom provides the user with an effective tool for understanding the composition of the bottom. The FSTN type display uses 4 discrete levels of gray to indicate the intensity of the returned sonar signal.

These are easily identified by the continuous nature of the return. Second Returns. When a sonar signal is reflected off the bottom back to the transducer, there is often enough energy left in the signal to be reflected off the...

  • Page 14: Control Functions

    USING THE 405SX CONTROL FUNCTIONS CONTROL FUNCTIONS The 405SX uses a simple six button keypad for all user input. Press any button and an audible “chirp” confirms the control input. If a button has no function or is inappropriate for the situation, an audible “error” is heard. The unit sounds multiple chirps.
  • Page 15 USING THE 405SX CONTROL FUNCTIONS When using the standard 2D View transducer, with the optional speed/temp sensor connected, the VIEW button toggles the display between the full-screen 2D View, the Chart View and the Large Digital Readout View. The Chart View, shows only the digital depth readout, leaving more screen area for fish location and bottom depiction.
  • Page 16 USING THE 405SX MENU FUNCTIONS DOWN ARROW symbols. The symbols indicate which ARROW button has a function in a particular situation. Either one or both ARROW buttons can be used to adjust the menu function. A hollow ARROW symbol means the corresponding ARROW button has no function.

  • Page 17: Menu Functions

    USING THE 405SX MENU FUNCTIONS Several of the menus are multi-step. In some situations if an adjustment is made, additional options become available for further adjustment. Examples of these multi-step menus are Depth Range, Depth Alarm and Zoom. See the detailed description of each function for further explanation.
  • Page 18 USING THE 405SX 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 19 USING THE 405SX MENU FUNCTIONS range setting. The unit no longer adjusts the Depth Range to the most appropriate range for bottom display. Often, the bottom may not be visible on-screen. The digital depth readout always determines the depth of the bottom, even if it is not visible on-screen.
  • Page 20 USING THE 405SX MENU FUNCTIONS “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. “Manual” Zoom provides detailed information of any area from the surface to the bottom. In “Manual”...
  • Page 21 USING THE 405SX MENU FUNCTIONS Depth Alarm. The 405SX contains an audible alarm to warn you of shallow water depths. The alarm is adjustable to depths of 2' to 99'. When the alarm is enabled, an audible alarm sounds if the water beneath the boat is equal to or less than the selected alarm depth.
  • Page 22 USING THE 405SX MENU FUNCTIONS Triplog. Triplog provides a running log of information based on input from the Temp/Speed sensor. Since Triplog requires information from the Temp/Speed sensor to operate, if this sensor is not detected by the 405SX, the Triplog menu will not appear as an option.
  • Page 23 USING THE 405SX MENU FUNCTIONS Contrast. The Contrast function allows the user to control the level of contrast of the LCD display. The 405SX will automatically adjust the display contrast to compensate for changing ambient temperatures; however, some situations may occur where manual adjustment will provide a higher level of contrast.
  • Page 24 USING THE 405SX MENU FUNCTIONS Bottom Black. There are two selections available: Off and On. The factory setting is Off. With this setting, the 405SX displays the bottom using 4 level grayscale. This allows you to determine the texture and relative hardness of the bottom.
  • Page 25 USING THE 405SX MENU FUNCTIONS Decreasing the value to a number less than zero shows fewer fish symbols on-screen. In this case smaller sonar returns are disregarded. This is useful for eliminating many small sonar returns when seeking larger species of fish. The 405SX remembers this selection even when the unit is powered off.

    USING THE 405SX USING DIAGNOSTIC Another frequent use of depth offset is to show the depth beneath the deepest point of the hull. A negative value equal to the distance from the transducer location and the deepest point of the hull will have the same effect as mounting the transducer at the deepest point.

    If you are using multiple transducers, switch between transducers to confirm the connections for each. Voltage Input. Another connection tested is the voltage input, and is especially helpful in diagnosing input voltage problems. The current input voltage is displayed. If voltage fluctuations or power supply in excess of 20 VDC or less than 10 VDC is suspected, use the diagnostic screen to confirm input voltage.

  • Page 28: Maintenance And Troubleshooting

    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 405SX, use the following troubleshooting guide before calling your dealer or sending your unit in for repair.
  • Page 29 MAINTENANCE MAINTENANCE/TROUBLESHOOTING 2. There is no transducer detected. The 405SX has the ability to detect and identify that a transducer is connected. First, ensure that an appropriate transducer connector is positioned correctly in the connector holder, and that the unit is fully seated on the mount. Second, inspect the transducer cable from end to end for breaks, kinks, or cuts in the outer casing of the cable.

    MAINTENANCE TROUBLESHOOTING 5. The unit comes on before I press POWER, and won’t turn off. Check the transducer cable—if the outer jacket of the cable has been cut and the cable is in contact with bare metal, you need to repair the cut with electrical tape. If there is no problem with the cable, disconnect the transducer from the unit and see if the problem is corrected, to confirm the source of the problem.
