USING THE 405SX

CONTROL FUNCTIONS

CONTROL FUNCTIONS

The 405SX 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 unit sounds multiple chirps.

Power. The Power button powers the 405SX 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. 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 405SX will consume more power than with the backlight off. This is important when using the 405SX 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 405SX menu-controlled user functions.

View. VIEW selects one of several screen configurations or “views” possible depending on the transducer in use. When using the standard 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. Pressing VIEW again will select the Large Digital Readout View, which increases the size of key digital information so that it can be viewed from a great distance. Normal 2D information is displayed on the right side of the display. Pressing VIEW again will toggle the display back to the 2D view.
