Transmit Rate

: Sets the length of time between sonar pings. 

Increasing the transmit rate increases the scroll speed, but it 

may also increase self-interference.
Reducing the transmit rate increases the spacing between 

transmit pulses and can resolve self-interference.

Transmit Power

: Reduces transducer ringing near the surface. 

A lower transmit power value reduces transducer ringing, but 

can also reduce the strength of the returns.

Filter Width

: Defines the edges of the target. A shorter filter 

more clearly defines the edges of the targets but may allow 

more noise. A longer filter creates softer target edges and 

may also reduce noise.

Transducer Diagnostics

: Shows details about the transducer.

Flip Left/Right

: Switches the SideVü view orientation from left 

to right.

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.

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.

Beam Width

: Sets the width of the Panoptix transducer beam.

Narrow beam widths allow you to see deeper and farther. 

Wider beam widths allow you to see more coverage area.

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.

Sonar Recordings

Recording the Sonar Display

NOTE: 

Not all models support sonar recording.

1

Insert a memory card into the card slot.

2

From a sonar view, select 

Menu

 > 

Sonar Setup

 > 

Sonar 

Recording

 > 

Record Sonar

.

15 minutes of sonar recording uses approximately 200 MB of 

space of the inserted memory card. You can record sonar 

until the card reaches capacity.

Stopping the Sonar Recording

Before you can stop recording sonar, you must begin recording 

it (

Recording the Sonar Display

, page 24

).

From a sonar view, select 

Menu

 > 

Sonar Setup

Playing Sonar Recordings

Before you can play back the sonar recordings, you must 

download and install the HomePort

 application and record 

sonar data onto a memory card.

1

Remove the memory card from the device.

2

Insert the memory card into a card reader attached to a 

computer.

3

Open the HomePort application.

4

Select a sonar recording from your device list.

5

Right-click the sonar recording in the lower pane.

Radar

 WARNING

The marine radar transmits microwave energy that has the 

potential to be harmful to humans and animals. Before 

beginning radar transmission, verify that the area around the 

radar is clear. The radar transmits a beam approximately 12° 

above and below a line extending horizontally from the center of 

the radar.
When the radar is transmitting, do not look directly at the 

antenna at close range; eyes are the most sensitive part of the 

body to electromagnetic energy.
When you connect your compatible chartplotter to an optional 

Garmin marine radar, such as a GMR

 Fantom

 6 radar or a 

GMR 24 xHD, you can view more information about your 

surroundings.
The radar transmits a narrow beam of microwave energy as it 

rotates to a 360° pattern. When the transmitted energy contacts 

a target, some of that energy is reflected back to the radar.

Changing the Radar Mode

1

From a combination screen or SmartMode layout with radar, 

select 

Menu

 > 

Radar Menu

 > 

Change Radar

.

2

Select a radar mode.

Transmitting Radar Signals

NOTE: 

As a safety feature, the radar enters standby mode after 

it warms up. This gives you an opportunity to verify the area 

around the radar is clear before beginning radar transmission.

1

With the chartplotter off, connect your radar as described in 

the radar installation instructions.

2

Turn on the chartplotter.
If necessary, the radar warms up and a countdown alerts you 

when the radar is ready.

3

Select 

Radar

.

4

Select a radar mode.
A countdown message appears while the radar is starting up.

5

Select 

Menu

 >

.

Stopping the Transmission of Radar Signals

From a radar screen, select 

Menu

 > 

Radar To Standby

.

TIP: 

Press   > 

Radar To Standby

 from any screen to 

quickly stop radar transmission.

Setting Up the Timed Transmit Mode

To help conserve power, you can set up time intervals in which 

the radar will transmit and not transmit (standby) signal 

transmissions.

NOTE: 

This feature is not available in dual radar modes.

1

From a radar screen, select 

Menu

 > 

Radar Options

 >

2

Select 

Timed Transmit

 to enable the option.

3

Select

.

4

Select 

Transmit Time

, enter the duration of each radar 

signal transmission, and select 

Done

.

Enabling and Adjusting a Radar No Transmit Zone

You can indicate an area within which the radar scanner does 

not transmit signals.

NOTE: 

This feature is not available on all radar and chartplotter 

models.
