1. Thru hull transducers install through a hole drilled in the hull of the boat Larger boats or boats with inboard motors create turbulence that make transom mounting ineffective Also hulls that are very thick or are double layered or made from materials such as wood or metal which do not conduct sonar signals make inside the hull mounting inadvisable 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 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 it to the address listed in Customer Support Some transducers may have additional cost Refer to the Accessory catalog or call Customer Support for information BEGINNING INSTALLATION Now that you have determined the transducer mounting method you can begin installation of your new Humminbird fishfinder The installation guide included on the next few pages 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 included with your manual In addition to the parts included you need the following2. the 100SX responds to control inputs as if it is in actual operation so feel free to experiment with the many features and functions to customize the 100SX for your particular operation To exit Simulator mode power the unit off WHAT YOU SEE ON SCREEN Your 100SX uses a 128 x 64 matrix FSTN LCD display This type of display provides outstanding viewability in all light conditions over a wide range of temperatures NOTE When in simulator mode the word simulator occasionally scrolls across the display indicating that the information on screen is not real sonar data At power up the depth range sensitivity and other user adjustments are set at their default settings There are several elements on screen which are common to all modes of operation The large digital number at the lower left of the display is the depth of the water directly beneath the transducer location The range of the graphic display is shown to the right of the SEE co Ts jel A graphic information The upper number is 0 indicating the g surface of the water the lower number is one of the 9 ranges available which best matches the depth of the water As the depth of the water changes the range changes as necessary in order to retain a bottom representation onscreen When in Auto mode the horizontal line at the top of the graphics area is the 0 line which represents the surface of the water Occasionally there will be a gap in this line This gap indicates that t
