System Operation
3.6 Display
Menu
The display menu is provided to allow the operator to configure the display ele-
ments to suit individual tastes and operating conditions.
3.6.1 Color
Six pre-set color schemes are available. The color Palette dictates the color-
coded amplitude values for the sonar wedge area.
Low to High amplitude color selections are:
Blk-Wht:
Continuous Black to White
Black:
Black only (very high contrast)
Dark:
Continuous Black to Dark Blue
Dim:
Continuous Dark Blue to Light Blue
Blu-Yel:
Continuous Dark Blue to Yellow
Vivid:
Continuous Dark Blue to Red
3.6.2 Contrast
This menu item allows the operator to set the contrast level for the display. This
setting has no effect on the data itself. Scaling factors available are X1.0, x1.25,
x1.5, and x2.0. The higher the number, the greater the contrast. A typical con-
trast value is x1.5.
3.6.3 Dots
The Dots menu provides the operator with the option to color-code each sound-
ing dot, depending on various factors. The choices available are:
Off:
No dots are displayed.
Normal:
Only soundings with a quality value of 3 are dis-
played. All dots are white.
All:
All soundings are white, regardless of their quality or
bottom detection process.
Quality:
Each sounding is displayed based upon the quality
value assigned:
Gray: Quality 0 - poor colinearity, poor brightness
Red: Quality 1 - poor colinearity, good brightness
Green: Quality 2 - good colinearity, poor brightness
Cyan: Quality 3 - good colinearity, good brightness
Process:
Each sounding is color-coded based upon the weight-
ing used in the Magnitude/Phase bottom detection
process.
Red: Magnitude detection
Green: Phase detection
Cyan: Blended magnitude/phase detection
