bottom can appear on the screen as long as it appears within

the range you have set.

Forward Range: Adjusts the range of the forward scale.

Allowing the device to adjust the range automatically adjusts

the forward scale in relation to the depth. Manually adjusting

the range enables you to view a specified range. The bottom

can appear on the screen as long as it appears within the

range you have set. Manually reducing this option can reduce

the effectiveness of the FrontVü Alarm, reducing your

reaction time to low depth readings.

Transmit Angle: Adjusts the focus of the transducer to the port

or starboard side. This is available only with RealVü capable

Panoptix FrontVü transducers, such as the PS30, PS31, and

PS60.

Transmit: Stops the transducer from transmitting.

FrontVü Alarm: Sets an alarm to sound when the depth in front

of the vessel is less than the specified value

Panoptix FrontVü transducers.

Sonar Setup: Adjusts the setup of the transducer and the

appearance of the sonar returns.

Edit Overlays: Adjusts the data shown on the screen.

Setting the LiveVü and FrontVü Transducer Transmit Angle

This feature is available only with Panoptix LiveVü and FrontVü

transducers.

You can change the transducer transmit angle to aim the

transducer at a particular area of interest. For example, you

might aim the transducer to follow a bait ball or focus on a tree

as you pass it.

From a LiveVü or FrontVü sonar view, select MENU >

Transmit Angle.

Select an option.

Setting the FrontVü Depth Alarm

The FrontVü depth alarm is a tool for situational awareness only,

and may not prevent groundings in all circumstances. It is the

obligation of the vessel operator to ensure safe operation of the

vessel.

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

25).

From the FrontVü sonar view, select MENU > FrontVü

Alarm.

Select On.

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.

(Setting the

WARNING

(Setting the Bow Offset,

CAUTION

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.

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

22).

This applies to Panoptix transducers with an internal

compass, such as the PS21-TR transducer.

Restore Sonar Defaults: Restores the sonar settings to the

factory default values.
