INSTALLATION OVERVIEW The 150SX consists of two primary components to install: the control head and the transducer. The control head contains the sonar transmit and receive circuitry, as well as the user controls and display.

Review the following section to determine the method that works for you and your boat. Determining How to Mount the Transducer The 150SX includes a model XHS-6-24 transducer. This transducer can be mounted on the transom of the boat, or bonded to the inside of a fiberglass hull boat.
ALTERNATE TRANSDUCERS AND MOUNTING METHODS The 150SX comes with everything necessary for installation and operation on most boats. However, there are several situations which may require a different type of transducer. Inboard boats, wood or metal hulls, and sail boats create unique transducer mounting needs.
BEGINNING INSTALLATION Now that you have determined the transducer mounting method, you can begin installation of the 150SX. 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.
SIMULATOR OPERATION The 150SX 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 150SX.
If you are using the 150SX in Simulator when no transducer is connected, any selected options are lost when the unit is powered off. The 150SX will return to Factory Settings, or options selected when last used with a transducer, if no transducer is connected.
USING THE 150SX WHAT YOU SEE ON-SCREEN What You See On-Screen Your 150SX uses a 128 V x 64 H matrix FSTN LCD display. This display provides outstanding viewability in all light conditions over a wide range of temperatures. At initial power-up, the 150SX uses settings that were set at the factory.

The best way to learn to interpret structure is to operate the 150SX over a variety of known conditions and experiment with user functions to best represent those conditions on-screen.
CONTROL FUNCTIONS The 150SX uses a simple five 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.

The backlight is very effective for low- light and nighttime operation. When the backlight is on, the 150SX will consume more power than with the backlight off. This is important when using the 150SX in a portable configuration powered by a separate battery, or when powering the unit from a trolling motor battery.
Menu Functions Sensitivity. The Sensitivity function controls the sensitivity of the sonar receiver. The 150SX automatically adjusts the level of receiver 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, propeller cavitation and hydrodynamic flow among others.
USING THE 150SX MENU FUNCTIONS down the total range (for example, in High Sensitivity Low Sensitivity 20' (6m) of water, the 0-30' (0-10m) range would be selected). This provides best display resolution therefore the best target separation possible. The Depth Range can be adjusted manually.

Use the ARROW buttons to highlight the desired selection. The 150SX will reset to the factory setting when the unit is powered off.

150SX interpret the raw sonar data and, using a variety of techniques, depict appropriate target returns as one of three different size fish symbols. The 150SX also displays the depth beneath the surface with the corresponding fish symbol. Selecting Adjust and making incremental changes enhances the fishfinder’s ability to identify sonar...

The 150SX remembers this selection even when the unit is powered off. Numeral Size. Two options are available: BIG and SMALL. The factory setting is BIG. With this setting, the digital depth and speed and temp numerals are drawn large enough to be read from across the boat.
The Reset function is an important first step in troubleshooting problems to ensure that a user selected setting is not the cause for the perceived problem. USING THE DIAGNOSTIC FEATURE The 150SX contains a powerful diagnostic tool that can aid in determining the cause of a problem.

Use Diagnostic while running the boat at high speeds to show the voltage gain. Also, if you are using the 150SX in portable configuration or from the trolling motor battery, Diagnostic can be used to evaluate the health of the battery by showing the current voltage.
TROUBLESHOOTING Do not attempt to repair the 150SX yourself. There are no user serviceable parts inside, and special tools and techniques are required for reassembly to ensure the waterproof integrity of the housing. Repairs should be performed only by authorized Humminbird technicians.
150SX, use the following troubleshooting guide before sending your unit in for repair. The 150SX contains several tools that can aid in determining if there is a problem and how to isolate and repair the problem in many cases.
