ACCESSORIES Humminbird offers a wide assortment of accessories that complement and expand the capability of your new fishfinder.

The Humminbird Accessory catalog included with your unit contains descriptions of the many accessories available and ordering information. [. . . ] The specific fish symbol indicates the type of sonar beam the fish is detected in. This gives you a reliable indicator of side to side location relative to boat movement. Fish symbols which are hollow are detected in the outside two beams. Hollow fish symbols facing to the right are in the right beam and therefore are to the right side of the boat (as viewed from the driver seat facing forward). Hollow fish symbols facing to the left are detected in the left beam, and thus the fish is to the left side of the boat. Solid fish symbols represent fish in the single center beam, and these fish are directly under the boat CONTROL FUNCTIONS The 400TX uses a simple six 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 Power button powers the 400TX up for normal operation. When the unit is on, POWER turns the unit off. POWER can also be used to go directly into Simulator mode. To enter simulator, with the unit powered off, press and hold POWER for several seconds until a continuous chirp is heard. LIGHT controls the unit's display backlight. With the unit powered on, press LIGHT once to turn the backlight on "low. " Press LIGHT a second time to turn the backlight on "medium, " a third time to turn the backlight on "high", and a fourth time to turn the backlight off. The backlight is very effective for low-light and nighttime operation. When the backlight is on, the 400TX will consume more power than with the backlight off. This is important when using the 400TX in a portable configuration powered by a separate battery, or when powering the unit from a trolling motor battery. 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 400TX menu-controlled user functions. VIEW selects one of several screen configurations or "views" possible depending on the transducer in use. When using the standard 2 (Tribeam) transducer, without the optional speed/temp sensor connected, the VIEW button toggles the display between the full-screen 2D View and the Large Digital Readout View. The 2D View is the default view, and the view which is first seen at power-up. [. . . ] The diagram is useful in ensuring that the center beam is present and of sufficient strength. The depth of the water beneath the boat is shown for each of the three beams. In operation, only the center beam is used to display this depth, however, the depth number is another means of comparison. When in diagnostic, two menus are available to the user: Depth Range, and Diagnostic. [. . . ]
