Sonar View
SONAR VIEW (Deep Models only)
selects the source of the
sonar information being
displayed. 200kHz displays
sonar information and FISH ID
from the 200kHz beam only.
50kHz displays sonar
information and FISH ID from
the 50kHz beam only. SPLIT
SCREEN presents the sonar
information from the 200kHz
and 50kHz beams
simultaneously in side-by-
side windows. 200KHZ/50KHZ
displays the sonar
information from the 200kHz
beam and target information
from the 50kHz beam.
The SONAR VIEW setting is retained in memory after the
unit is turned off. The factory setting is 200KHZ.
Light
LIGHT activates the display
backlight and selects the
brightness level. The
backlight is manually-
controlled except when the unit first powers up.
During initial power up, the backlight turns on at full
brightness so the display will be visible at night. The
backlight will then begin to decrease in intensity
automatically until it is off in order to save energy.
Selecting the CONTROL PANEL LIGHT choice stops the
automatic off process, keeping the backlight on at the
intensity level selected.
The Light setting defaults to factory settings after the
Legend 2000 Series is turned off. The factory setting
is ON full at power up and automatic decrease to OFF.
Contrast
CONTRAST enhances the
viewability of the LCD by
making it darker or lighter.
Selecting a higher number
darkens the display; selecting a lower number lightens
the display. The
LEGEND 2000 SERIES uses sophisticated
electronics to adjust the contrast level automatically;
however, at times of extreme heat or cold, manually
adjusting the contrast for best display may be needed.
The CONTRAST setting is retained in memory after the unit is turned off as
long as it is set between 6 and 10. The factory setting is
8.
RTS Window
RTS WINDOW selects the width of
the window dedicated to REAL
TIME SONAR™. Selecting NARROW
decreases the width of the
RTS WINDOW leaving more space for the CHART WINDOW, but
some sonar returns will not be visible. Selecting WIDE
makes the RTS WINDOW wider and shows more of the
sonar intensity information, but less space on the LCD
is available for sonar history. Selecting OFF turns off the
RTS WINDOW and the entire LCD shows sonar history.
Note: When the RTS Window is adjusted to Wide, no grayscale
information is shown.
The RTS WINDOW setting is retained in memory after the
LEGEND 2000 SERIES is turned off. The factory setting is
NARROW.
Surface Clutter
SURFACE CLUTTER eliminates most
sonar returns near the water
surface caused by trapped air,
boat wakes and temperature
inversions. Most surface clutter appears on the
display because the strongest sonar returns come
from the shallowest objects. The LEGEND 2000 SERIES uses
a sophisticated feature called TVG (Time Variable
Gain) to overcome surface clutter and counteract the
effect of depth on sonar return strength. The level 1
setting is optimal for making sonar information from
all depths appear uniformly. Many users, however,
prefer to see more surface clutter than this setting
shows. Selecting a higher number shows more
surface clutter, but sonar returns nearest the surface
will appear more intense than they actually are.
The SURFACE CLUTTER setting is retained in memory after the
LEGEND 2000 SERIES is turned off. The factory setting is 4.
