INSTALLATION PREPARATION INSTALLATION OVERVIEW Determining How to Mount the Transducer Your Humminb ird fishfinder includes a standard transducer. This transducer can be mounted on the transom of the boat or bonded to the inside of a fiberglass hull boat. The transom installation, which is the most widely used, places the transducer on the outside [...]

INSTALLATION PREPARATION ALTERNATE M OUNTING METHODS ALTERNATE TRANSDUCERS AND MOUNTING METHODS Your Humminbird fishfinder comes with everything necessary for installation and operation on most boats. However, there are several situations which may require a different type of transducer. In board boats, wood or metal hulls, and sail boats create un[...]

INSTALLATION PREPARATION TRANSDUCER EXCHANGE TRANSDUCER EXCHANGE Other transducers are available as replacements for the standard transducer. You may exchange your new and unassembled transducer for another type by returning i t to the address listed in Customer Support. Some transducers may have additional cost. Refer to the Accessory catalog or c[...]

INSTALLAT ION TRANSOM INSTALLATION Do not begin this transducer installation until you read the Installation Preparation in the Operation Guide. This chapter contains information critical to the correct installation of your transducer. Due to the wide variety of b oat hulls, only general instructions are presented in the installation guide. Each bo[...]

INSTALLATION TRANSOM INSTALLATION • If the propeller(s) is (are) forward of the transom, it may be impossible to find an area clear from turbulence, and a different mounting technique or transducer type should be considered. Step Two - Drill the Mounting Holes 1. Remove the mounting template from the front of the Operations Manual. 2. Hold the te[...]

INSTALLATION TRANSOM INSTALLATION Step Four - Mount the Transducer to the Transom 1. Apply silicone sealant to the mounting holes drilled into the transom. 2. Align the transducer assembly with the drilled holes in the transom (Figure 8). 3. U se either a flat head screwdriver, a 5/16" (8mm) hex driver, or a 5/16" (8mm) socket to mount th[...]

mounting bracket. Drill this hole and install the screw after final testing and adjustments have been completed.[...]

INSTALLATION TRANSOM INSTALLATION Step Six - Route the Cable There are several ways to route the transducer c able to the to the area where the control head will be installed. The most common procedure routes the cable through the transom into the boat. Inside the boat there is often a channel or conduit used for other wiring that the cable can be [...]

INSTALLATION INSIDE THE HULL INSTALLATION INSIDE THE HULL INSTALLATION Inside the hull installation requires the mount system and control head be installed and operational. See Installing the Control Head for instruction on installing the unit. Inside the hull mountin g generally produces good results in single thickness fiberglass - hulled boats. [...]

The transducer cannot transmit through air. The water purges any air from between the transducer and the hull and fills any voids in the coarse fiberglass surface.[...]

INSTALLATION INSIDE THE HULL INSTALLATION 3. Power up the Control Head. 4. Run the boat at various speeds and water depths while observing the screen on the Control Head. If the unit functions well at low speeds but b egins to skip or miss the bottom at higher speeds, the transducer needs to be moved. If depth performance is required, test the fish[...]

INSTALLATION CONTROL HEAD INSTALLATION CONTROL HEAD INSTALLATION Step One - Determine Where to Mount Begin the installation by determining where to mount the control head. Consider the following to determine best location: • The cables for power, transducer and temp/speed accessories (if applicable) should be installed first and must reach the mo[...]

fuse in the connection. If you must wire the control head directly to a battery, be sure to install an inline fuse holder[...]

INSTALLATION CONTROL HEAD INSTALLATION and one amp fuse (not inc luded) for the protection of the unit (Figure 21). Humminbird is not responsible for over voltage or over current failures. In order to minimize the potential for interference with other marine electronics a separate power source (such as a second batter y) may be necessary. Step Thre[...]

Optional: If the ca bles pass outside the mounting bracket, install the hole cover over the hole and fasten in place using the two #8 x 7/8” (22mm) wood screws (Figure 24).[...]

INSTALLATION CONTROL HEAD INSTALLATION Step Five - Assembling the Connector Holder 1. Insert the cabl e connectors into the connector holder. The cable connectors are labeled, and there are corresponding labels on the connector holder (Figure 26). The slots for the connectors are keyed to prevent reverse installation, so do not force the connector [...]

INSTALLATION TEST THE INSTALLATION TEST THE INSTALLATION Testing should be performed with the boat in the water, however you can initially confirm basic operation with the boat trailered. Press POWER once to turn the unit on. There will be an audible chirp when any button is pressed to confirm the button press. If the unit does not power - up, ensu[...]

HOW SONAR WORKS Yo ur 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. With this signal it determines d istance by measuring the time between the transmission of the sound wave an[...]

large digital number at the lower left of the display is the depth of the water directly beneath the trans ducer location. The range of the graphic display is shown to the right of the graphic information. The upper number is 0 indicating the surface of the water, the lower number is one of the 9 ranges available which best matches the depth of the[...]

Sonar targets which are not physically attach ed to the bottom may take one of many shapes. Surface clutter is the layer of water near the surface which is rich in algae and other growth, and often is aerated by wind or wave action. This area of water interferes with sonar transmission and often appea rs on - screen as regular clusters of individua[...]

CONTROL FUNCTIONS The 100SX uses a simple 5 - button keypad for all user input. When any button is pressed, an audible "chirp" confirms the control input. In the event that a particular button has no function or is inappropriate for the situation, an audible "error", or multiple chirps, will be heard. POWER, powers the 100SX up [...]

a nd DOWN ARROW symbols to the left of the menu indicate which buttons are available for adjustment . In menus which have numerous possible settings such as depth range, a range of adjustment indicator shows the total range available and the current setting. Within the menu are the options available. The selected option or current setting is highli[...]

If a setting limit is reached, the ARROW symbol attached to the menu appears to be hollow which indicates that the related button has no further function. Also, the audible "error" consisting of multiple chirps will be heard. After an adjustment is made, the menu disappears and the new sensitivity setting begins to affect new sonar inform[...]

To return to "Automatic" Depth Range control, press the MENU button until the Depth Range menu appea rs on - screen and use the UP ARROW to select AUTO. The 100SX returns to Automatic operation. Zoom Zoom is similar to Depth Range in that it controls the range of information displayed in the graphics area of the display. Zoom, however, al[...]

Once "Manual" Zoom is selected, the display will appear the same as in "Auto" Zoom, but the zoom range does not change automatically. If further adjustment of the zoom range is necessary, pressing either ARROW button while Zoom is active will move t he Zoom range up or down. The Menu returns briefly to show the numeric values as[...]

Once the Fish Alarm is enabled, the 100SX emits an audible beep when the selected size fish sy mbol appears on - screen. The sound is slightly different for each of the three fish symbol sizes, so with practice, it is possible to distinguish the size of the detected fish without looking at the unit. To disable the Fish Alarm, press MENU until the F[...]

USING DIAGNOSTIC The 100SX contains a powerful diagnostic tool which can aid in determining the cause of a problem. To enab le Diagnostic, power the unit on and use the DOWN ARROW button to highlight the Diagnostic option on the initial screen. Diagnostic can only be accessed at power - up. After the menu times out, the first of two diagnostic scre[...]
