2 INST ALLA TION PREP ARA TION P ARTS SUPPLIED P ARTS SUPPLIED Before installing your 405SX , please ensur e the following parts are included in the box: • 405SX fishfinder • T ransducer with 20&a.
3 INST ALLA TION PREP ARA TION INST ALLA TION OVERVIEW The transducer converts electrical energy from the transmitter into mechanical pulses or sound waves. The transducer also receives the r eflected sound waves and converts them back into electrical signals for display on the control head.
4 Inside the hull installations requir e no holes to be drilled into the boat and through experimentation, high-speed operation comparable to transom mounting can be achieved.
BEGINNING INST ALLA TION 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 contr ol head and transducer .
USING THE 405SX HOW SONAR WORKS 6 HOW SONAR WORKS Y our 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. Y our Humminbird unit sends out a sound wave signal.
7 USING THE 405SX SIMULA TOR OPERA TION the DOWN ARROW until “ Simulator ” is highlighted. When the screen times out, the unit will be in simulator mode. When in simulator operation, the 405SX responds to contr ol inputs as if it is in actual operation, so feel free to experiment, or to customize the unit for your particular operation.
T emperature/Speed. The initial screen layout takes one of two basic forms depending on whether the optional T emp/Speed accessory is installed. Figure A shows the default view when the T emp/Speed accessory is installed. Figure B shows the default view when the T emp/Speed accessory is not installed.
This range is selected so the bottom repr esentation is typically shown about ²⁄₃ 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 r etur ned sonar signal.
Thermoclines. Thermoclines are sharp differ ences in water temperature. These ar e easily identified by the continuous nature of the r etur n. Second Returns.
repeat the same image it is often necessary to travel the same speed and direction over the location wher e the structure was originally located. The 405SX is also capable of showing layers of water having different temperatures. These temperatur e differences, called thermoclines, appear at differ ent depths, depending on current conditions.
CONTROL FUNCTIONS The 405SX uses a simple six button keypad for all user input. Press any button and an audible “ chirp ” confirms the contr ol input. If a button has no function or is inappropriate for the situation, an audible “ error ” is heard.
When using the standard 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 scr een area for fish location and bottom depiction.
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.
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.
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-scr een indefinitely . If you need to make an additional adjustment, press the UP ARROW or DOWN ARROW button.
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.
“ 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 pr ovides detailed information of any area fr om the surface to the bottom.
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.
T riplog. T riplog provides a running log of information based on input from the T emp/Speed sensor . Since T riplog requires information from the T emp/Speed sensor to operate, if this sensor is not detected by the 405SX, the T riplog menu will not appear as an option.
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.
Bottom Black. There ar e 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 har dness of the bottom. Selecting Bottom Black “ ON ” causes the unit to blacken in the display below the bottom.
Decreasing the value to a number less than zer o shows fewer fish symbols on-screen. In this case smaller sonar returns are disr egarded. 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 of f.
Another frequent use of depth of fset 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.
MAINTENANCE If you are using multiple transducers, switch between transducers to confirm the connections for each. V oltage Input. Another connection tested is the voltage input, and is especially helpful in diagnosing input voltage problems. The curr ent input voltage is displayed.
26 • If your boat remains out of the water for a long period of time, it may take some time to wet the transducer when returned to the water . Small air bubbles can cling to the surface of the transducer and interfere with pr oper operation.
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 appr opriate transducer connector is positioned correctly in the connector holder , and that the unit is fully seated on the mount.
28 5. The unit comes on before I press POWER, and won’t turn of f. 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 r epair the cut with electrical tape.
