obligation of the vessel operator to ensure safe operation of the

This alarm is available only with Panoptix FrontVü transducers.
You can set an alarm to sound when the depth is below a
specified level. For best results, you should set the bow offset
when using the front collision alarm
page

1
From the FrontVü sonar view, select MENU > FrontVü
Alarm.
2
Select On.
3
Enter the depth at which the alarm is triggered, and select
Done.
On the FrontVü screen, a depth line shows the depth at which
the alarm is set. The line is green when you are in a safe depth.
The line turns yellow when you are going faster than the forward
range gives you time to react (10 seconds). It turns red and
sounds an alarm when the system detects an obstruction or the
depth is less than the entered value.
The ability to effectively avoid running aground with FrontVü
sonar decreases as your speed rises above 8 knots.
LiveVü and FrontVü Appearance Settings
From a LiveVü or FrontVü Panoptix sonar view, select MENU >
Sonar Setup > Appearance.
Color Scheme: Sets the color palette.
Color Gain: Adjusts the intensity of colors shown on the screen.
You can select a higher color gain value to see targets higher
in the water column. A higher color gain value also allow you
to differentiate low intensity returns higher in the water
column, but this causes a loss in the differentiation of the
returns at the bottom. You can select a lower color gain value
when targets are near the bottom, to help you distinguish
between targets and high intensity returns such as sand,
rock, and mud.
Trails: Sets the how long the trails appear on the screen. The
trails show the movement of the target.
Bottom Fill: Colors the bottom brown to distinguish it from the
water returns.
Grid Overlay: Shows a grid of range lines.
Scroll History: Shows the sonar history in a traditional sonar
view.
RealVü Appearance Settings
From a RealVü sonar view, select MENU > Sonar Setup >
Appearance.
Point Colors: Sets a different color palette for the sonar return
points.
Bottom Colors: Sets the color scheme for the bottom.
Bottom Style: Sets the style for the bottom. When you are in
deep water, you can select the Points option and manually
set the range to a shallower value.
Color Key: Shows a legend of the depths the colors represent.
Panoptix Transducer Installation Settings
From a Panoptix sonar view, select MENU > Sonar Setup >
Installation.
Install Depth: Sets the depth below the water line where the
Panoptix transducer is mounted. Entering the actual depth at
which the transducer is mounted results in a more accurate
visual presentation of what is in the water.
Bow Offset: Sets the distance between the bow and the forward
view Panoptix transducer installation location. This allows
you to view the forward distance from the bow instead of the
transducer location.

CAUTION
This applies to Panoptix transducers in the FrontVü, LiveVü
Forward, and RealVü 3D Forward sonar views.
Beam Width: Sets the width of the down view Panoptix
transducer beam. Narrow beam widths allow you to see
deeper and farther. Wider beam widths allow you to see
more coverage area.
This applies to Panoptix transducers in the FrontVü, LiveVü
Down, and LiveVü Forward sonar views.
Use AHRS: Enables the internal attitude heading and reference
system (AHRS) sensors to detect the installation angle of the
Panoptix transducer automatically. When this setting is
turned off, you can enter the specific installation angle for the
transducer using the Pitch Angle setting. Many forward view
transducers are installed at a 45-degree angle and down
view transducers are installed at a zero-degree angle.
Flipped: Sets the orientation of the Panoptix sonar view when
the down view transducer is installed with the cables pointing
toward the port side of the boat.
This applies to Panoptix transducers in the LiveVü Down,
RealVü 3D Down, and RealVü 3D Historical sonar views.
Calibrate Compass: Calibrates the internal compass in the
Panoptix transducer
(Transducer Installation Settings,
page
23).
This applies to Panoptix transducers with an internal
compass, such as the PS21-TR transducer.
Orientation: Controls if the transducer is in down or forward
installation mode. The Auto setting uses the AHRS sensor to
determine the orientation.
This applies to PS22 and LiveScope transducers.
Focus: Adjusts the sonar view to compensate for the speed of
sound in water. The Auto setting uses the temperature of the
water to calculate the speed of sound.
This applies to LiveScope transducers.
Restore Sonar Defaults: Restores the sonar settings to the
factory default values.
Setting the Bow Offset
For forward view Panoptix transducers, you can enter a bow
offset to compensate the forward distance readings for the
transducer installation location. This allows you to view the
forward distance from the bow instead of the transducer
installation location.
This feature applies to Panoptix transducers in the FrontVü,
LiveVü Forward, and RealVü 3D Forward sonar views.
