USER INTERFACE
The
L
EGEND
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
L
EGEND
3000 S
ERIES
control all
user settings: M
ODE
, G
AIN
, C
ONTROL
P
ANEL
and R
ANGE
.
Mode Knob
The M
ODE
knob selects how the
L
EGEND
3000 S
ERIES
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 G
AIN
knob controls the gain
(sometimes called sensitivity) of the
sonar receiver. Gain also powers the
unit on or off. When the
L
EGEND
3000
S
ERIES
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
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 C
ONTROL
P
ANEL
knob accesses features used to adjust some
L
EGEND
3000 S
ERIES
settings. Push the knob to display the C
ONTROL
P
ANEL
list, then
rotate the knob to select a feature for adjustment. A light colored
background indicates the selected feature. Turn the R
ANGE
knob to adjust
the selected feature. Remove the C
ONTROL
P
ANEL
list from the display by
pushing the C
ONTROL
P
ANEL
knob again. If no adjustments are made after a
few seconds, the C
ONTROL
P
ANEL
list is removed automatically.
Range Knob
The R
ANGE
knob adjusts the depth ranges used on the display. The R
ANGE
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
small increments, while turning it quickly
makes large changes to the adjustment.
The LCD Display
The
L
EGEND
3000 S
ERIES
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
L
EGEND
3000
S
ERIES
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 A
UTOMATIC
and Bottom
Lock modes, the
L
EGEND
3000 S
ERIES
selects the depth range. In M
ANUAL
mode, the depth range is selected by the user.
The sonar returns received by the
L
EGEND
3000 S
ERIES
are displayed along
the depth range scale in a R
EAL
T
IME
S
ONAR
(RTS) W
INDOW
and
C
HART
W
INDOW
. The RTS W
INDOW
displays new sonar information
within the transducer cone in an
expanded, easy-to-see format;
the C
HART
W
INDOW
logs old RTS
W
INDOW
information to show a
contour view of the bottom and
structure.
