Color
Strong and weak signals have different colors to indicate the different signal strengths. The
colors used depend on which palette you select. The more you increase the Color setting,
the more echoes are displayed in the color at the strong return end of the scale.
To set the Color:
• press the Color softkey once, then turn the rotary knob to adjust the value.
Display time
You can change the length of the depth history shown on the display. This does not affect
already collected data, so the length of depth history shown will gradually change from the
old to the new value when changing display time.
The numeric value (
A
) in the lower-left corner of the panel always shows the age of the
leftmost column on the screen.
A zebra scale (
B
) is shown at the bottom of the image, and each stripe equals one minute.
If there is a discontinuity in the depth signal, this is indicated with a triangle (
C
).

Optional image items
Palettes
You can select between several display palettes.
White marker
Use this option to change a specific color on the image to white. This effectively highlights
(or hides) the selected color.
Bottom line
The bottom line option makes it easier to distinguish the bottom from other objects. You can
specify the thickness of the line.
Advanced options
Frequency
The unit supports several transducer frequencies. Available frequencies depend on the
transducer model that is configured for use.
Noise rejection
Signal interference from bilge pumps, engine vibration and air bubbles can clutter the
image.
The noise rejection option filters the signal interference and reduces the on-screen clutter.
TVG
Wave action and boat wakes can cause onscreen clutter near the surface. The TVG (Time
Variable Gain) option reduces surface clutter by decreasing the sensitivity of the receiver near
the surface.
