4 AL TERNA TE TRANSDUCERS AND MOUNTING METHODS The 105SX comes with everything necessary for installation and operation on most boats. However , there are several situations which may r equire a differ ent type of transducer . Inboard boats, wood or metal hulls, and sail boats create unique transducer mounting needs. Alternate transducers and mount[...]

TRANSDUCER EXCHANGE Other transducers are available as r eplacements for the standard transducer . Y ou may exchange your new and unassembled transducer for another type by returning it to the address listed in Customer Support. Some transducers may have additional costs. Refer to the Accessory cata- log or call Customer Support for information. BE[...]

USING THE 1 05SX 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. With this signal it determines distance by measuring the time between th[...]

7 USING THE 1 05SX SIMULA TOR OPERA TION SIMULA TOR OPERA TION The 105SX contains a simulator that allows you to use the unit as if you are on the water . The simulator is invaluable for learning how to operate the 105SX. There ar e two ways to start the simulator . If the unit is powered of f, press and hold the POWER button for approximately thr [...]

If you are using the 105SX in Simulator when no transducer is connected, any selected options are lost when the unit is power ed off. The 105SX will return to Factory Settings, or options selected when last used with a transducer , if no transducer is connected. IMPORT ANT : A transducer must be connected to the 105SX in order to r etain user setti[...]

When in Auto mode, the horizontal line at the top of the screen is the “zero line,” r epresenting 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 is not changing. New sonar information appears on th[...]

Structure. Structur e is defined as any object physically attached to the bottom. The sonar configuration of the 105SX is optimized to give the most accurate depiction of bottom structure possible. Grass, tr ees, stumps, wrecks or other debris ar e accurately displayed, however the depiction of these objects varies with boat speed and direction. Th[...]

differ ent species of fish have differ ent sonar characteristics, so it is not always possible to distinguish fish size between varying species. The signal intensity is “normalized” for depth so a small fish close to the boat does not appear as a large fish symbol. ID + adds an additional piece of information to help the user locate fish. On se[...]

12 When powering the unit from a battery such as in portable applications, you can prolong the battery life by using the backlight at a minimum. The three lower buttons, MENU, UP ARROW , and DOWN ARROW work together to control the 105SX menu-contr olled user functions. Menu. MENU displays a menu on- screen for adjustment. In normal operation, press[...]

13 Menu Layout. All menus use the same basic layout. The heading at the top describes the menu function. The UP ARROW and DOWN ARROW symbols to the left of the menu indicate which buttons are available for adjustment. In menus that have several possible settings, a range of adjustment indicator shows the total range available and the current settin[...]

Menu Functions Sensitivity . The Sensitivity function controls the sensitivity of the sonar receiver . The 105SX automatically adjusts the level of r eceiver sensitivity based on a number of factors including the depth of the water and the level of noise present. Noise can be caused by other electronic devices, engines, trolling motors, pr opeller [...]

15 USING THE 1 05SX 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 r emain on- screen indefinitely . If you need to make an additional adjustment, press the UP ARROW or DOWN ARROW button. Dept[...]

Using manual Depth Range control, you can view sonar information from the area near the surface in gr eater detail. To r eturn to automatic Depth Range control, pr ess the MENU button until the Depth Range menu appears on- screen and use the UP ARROW to select AUTO. Zoom. Zoom is similar to Depth Range because it controls the range of information d[...]

17 USING THE 1 05SX MENU FUNCTIONS The Zoom range is shown on the left side of the screen and full range information is shown on the right side of the display . Zoom can either operate automatically , in 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[...]

Depth Alarm. The 105SX contains an audible alarm to warn you of shallow water depths. The alarm is adjustable to depths of 3' to 99' (30m). 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. The alarm sounds continuously for about five seconds, and then inter[...]

Bottom Black. There ar e two selections available: Off and On. The factory setting is Off. With this setting, the 105SX displays the bottom using Structure ID. This allows you to determine the texture and r elative hardness of the bottom. Selecting Bottom Black “ON” causes the unit to blacken in the display below the bottom. This gives the user[...]

20 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. Decreasing the value to a number less than zero shows fewer fish symbols on-screen. In this case smaller sonar returns are disregar ded. This is useful for eliminati[...]

21 voltage from your boat’ s electrical system. The time, speed and distance calculations are useful for tracking your progr ess on a trip. The input voltage is useful for determining the condition of the charging system of the boat. When used in a portable application or whenever the 105SX is operated from a battery sour ce, the voltage number c[...]

22 MAINTENANCE AND W ARRANTY MAINTENANCE especially helpful in diagnosing input voltage problems. The pr esent 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. Often, small outboard motors do not ef fectively r egulate voltag[...]

23 MAINTENANCE AND W ARRANTY TROUBLESHOOTING •If your boat remains in the water for long periods of time, algae and other marine growth can r educe the effectiveness of the transducer . Periodically clean the face of the transducer with liquid detergent. Pivoting the transducer up in the bracket may allow better access for inspection or cleaning.[...]

24 Check the power connection to the 105SX. It is possible to force the power cable connector into the cable holder incorrectly . If the connector is reversed, the unit will not work. Examine the contacts on the back of the unit to ensure ther e is no corrosion. Finally , ensur e the unit is firmly seated on the mount. The electrical contacts are n[...]

25 the transducer is connected to the unit through a switch, temporarily connect it directly to the unit and try again. If none of these items identifies an obvious problem, the transducer itself may be the pr oblem. Be sure to include the transducer if r eturning the unit for repair . 4. When in very shallow water , I get gaps in the bottom readin[...]

26 can be caused by other electronic devices. T urn off any nearby electronics and see if the problem goes away . Noise can also be caused by the engine. If engine noise is causing the interference, the pr oblem will intensify at higher RPMs. Increase the engine speed with the boat stationary to isolate this cause. Propeller cavitation can appear a[...]
