Depth, Temp and Speed readouts
The sonar returns received by the LEGEND 3000 SERIES are displayed along the depth range scale in a REAL
TIME SONAR (RTS) WINDOW and CHART WINDOW. The RTS WINDOW
displays new sonar information within the transducer cone in an expanded, easy-to-see format; the CHART WINDOW logs old RTS WINDOW information to show a contour view of the bottom and structure.

The LCD Display
The LEGEND 3000 SERIES uses a high-
resolution LCD display to show sonar information, digital depth, temperature, speed and other readouts.
A digital depth readout is always displayed
in the upper left corner of the LCD. When the speed/temp accessory is connected,
additional digital readouts (such as MPH) are shown below the depth. A voltage
readout appears in the bottom left when the input voltage to the LEGEND 3000 SERIES is less than 11 volts or greater than
15 volts. A depth range scale appears close to the
right side of the LCD display. This scale
indicates the distance from the surface of the water to a depth range sufficient to
show the bottom. For example, in 18 feet of water, a 20 foot depth range is selected. The depth range scale can be controlled automatically or manually depending on the mode of operation. In AUTOMATIC and Bottom Lock modes, the LEGEND 3000 SERIES selects the depth range. In MANUAL mode, the depth range is selected by the user.

USER INTERFACE

The LEGEND 3000 User Interface is made up of the following components: knobs and the LCD Display, which in turn is made up of the RTS and the Chart Windows.

Knobs

Four knobs on the LEGEND 3000 SERIES control all user settings: MODE, GAIN, CONTROL PANEL and RANGE.

Mode Knob

The MODE knob selects how the LEGEND 3000 SERIES locates the bottom and graphs the information on the display. Turn the knob until the pointer aligns with the desired mode of operation. See Modes of Operation for more information.

Gain Knob

The GAIN knob controls the gain (sometimes called sensitivity) of the sonar receiver. Gain also powers the unit on or off. When the LEGEND 3000 SERIES is off, press Gain to turn the unit on. Press and hold Gain to turn the unit off. Turn the Gain knob clockwise to increase the gain; turn counterclockwise to decrease the gain. As you turn the knob, only new sonar information being graphed shows the effect of the gain change.

Increasing the gain shows faint sonar returns from small bait fish and

suspended debris in the water, but Maximum Gain Low Gain the display may become too

cluttered in some water conditions.

Increased gain is also beneficial at deeper depths to maintain a good bottom image and show adequate sonar returns from deep objects. Decreasing the gain eliminates the clutter from the display; however, if adjusted too low, the display may not show many faint sonar returns that could be fish.

Control Panel Knob

The CONTROL PANEL knob accesses features used to adjust some LEGEND 3000 SERIES settings. Push the knob to display the CONTROL PANEL list, then rotate the knob to select a feature for adjustment. A light colored background indicates the selected feature. Turn the RANGE knob to adjust the selected feature. Remove the CONTROL PANEL list from the display by pushing the CONTROL PANEL knob again. If no adjustments are made after a few seconds, the CONTROL PANEL list is removed automatically.

Range Knob

The RANGE knob adjusts the depth ranges used on the display. The RANGE knob has slightly different capabilities in each mode of operation. See Modes of Operation for specific information. In all modes, turning the knob clockwise increases the range, while turning it counterclockwise decreases the range. Turning the knob slowly increases the adjustment in
