Connect the power cable to the boat battery.

Connect the power cable to the POWER port on the radar.

Connecting the power cable directly to the battery is recommended. If it is

necessary to extend the cable, the appropriate gauge of wire must be used for

the length of the extension.
You must use crimp connectors and heat-shrink to create a water-resistant

connection.

3 m (9 ft. 10 in.)

3.31 mm² (12 AWG)

5 m (16 ft. 4 in.)

5.26 mm² (10 AWG)

The radar (and voltage converter, if applicable) must be connected to the

appropriate type of ground using a 3.31 mm² (12 AWG) copper wire (not

included).

Route a 3.31 mm² (12 AWG) copper wire to a water ground location and to

the radar pedestal.

Connect the wire to the ground connector on the pedestal ( ) using the

pre-installed crimp connector.

Coat the ground screw and crimp connector with marine sealant.

Connect the other end of the wire to the water ground location on the boat,

and coat the connection with marine sealant.

Select an option:
• If your radar was not packaged with a voltage converter, no further

grounding is necessary.

• If your radar was packaged with a voltage converter, proceed to step 6.

Route a different 3.31 mm² (12 AWG) copper wire to water ground location

and to the voltage converter.

Loosen a screw on one corner of the voltage converter and secure the

copper wire to the screw.

Coat the screw and wire on the voltage converter with marine sealant.

Connect the other end of the wire to the RF ground location on the boat,

and coat the connection with marine sealant.

This device connects to Garmin Marine Network devices to share radar data

with compatible devices on the network. When connecting to a Garmin Marine

Network device, observe these considerations.
• A Garmin Marine Network cable must be used for all Garmin Marine

Network connections.

◦ Third-party CAT5 cable and RJ45 connectors must not be used for

Garmin Marine Network connections.

◦ Additional Garmin Marine Network cables and connectors are available

from your Garmin dealer.

• Although it is not recommended, you can use a field-installable connector

to create a custom-length Garmin Marine Network cable if necessary.

Follow the directions provided with the connector.

All functions of this radar are controlled with your Garmin chartplotter. See the

Radar section of your chartplotter's manual for operating instructions. To

download the latest manual, go to www.garmin.com/support/.

You may need to update the device software when you install the device or

add an accessory to the device.

The device may contain a software-update memory card. If so, follow the

instructions provided with the card. If a software update memory card is not

included, you must copy the software update to a memory card.

Insert a memory card into the card slot on the computer.

Go to www.garmin.com/support/software/marine.html.

Select Download next to “Garmin Marine Network with SD card.”

Read and agree to the terms.

Select Download.

Select Run.

Select the drive associated with the memory card, and select Next >

Finish.

Before you can update the software, you must obtain a software-update

memory card or load the latest software onto a memory card.

Turn on the chartplotter.

After the home screen appears, insert the memory card into the card slot.
NOTE: In order for the software update instructions to appear, the device

must be fully booted before the card is inserted.

Follow the on-screen instructions.

Wait several minutes while the software update process completes.
The device returns to normal operation after the software update process

is complete.

Remove the memory card.
NOTE: If the memory card is removed before the device restarts fully, the

software update is not complete.

Before you can use the radar on your system, you must specify the antenna

size.
You must mount the radar, connect it to power, and connect it to the Garmin

Marine Network before you can specify the antenna size.

Turn on the radar and all devices connected to the Garmin Marine

Network.
An antenna-selection prompt appears on the connected chartplotters.
NOTE: If the entire system is being powered on for the first time, the

antenna-selection screen is part of the initial setup process.

Select the installed antenna size for each open-array radar installed on the

boat.
TIP: If you need to specify a different antenna size, while viewing the radar

screen for the radar you want to change , select Menu > Radar Setup >

Antenna Configuration > Antenna Size and select the antenna size.

The front-of-boat offset compensates for the physical location of the radar

scanner on a boat, if the radar scanner does not align with the bow-stern axis.

The front-of-boat offset compensates for the physical location of the radar

scanner on a boat, if the radar scanner does not align with the bow-stern axis.

Using a magnetic compass, take an optical bearing of a stationary target

located within viewable range.

Measure the target bearing on the radar.

If the bearing deviation is more than +/- 1°, set the front-of-boat offset.
