FOREWORD
A Word to the Owner of the DRS6A-NXT Marine Radar
Congratulations on your choice of the FURUNO DRS6A-NXT Marine Radar. We are confident you
will see why the FURUNO name has become synonymous with quality and reliability.
Since 1948, FURUNO Electric Company has enjoyed an enviable reputation for innovative and
dependable marine electronics equipment. This dedication to excellence is furthered by our
extensive global network of agents and dealers.
Your equipment is designed and constructed to meet the rigorous demands of the marine envi-
ronment. However, no machine can perform its intended function unless properly installed and
maintained. Please carefully read and follow the operation and maintenance procedures set forth
in this manual.
We would appreciate feedback from you, the end-user, about whether we are achieving our pur-
poses.
Thank you for considering and purchasing FURUNO equipment.
Features
• TARGET ANALYZER* function displays targets which are moving and getting close to own ship
in red, other targets in green and rain clutter in blue. Speed analyzing range is ±50 kn.
* Requires a GPS sensor. When you change the setting of [Target Analyzer Mode] to [Rain],
rain clutter is displayed.
• AUTO TARGET ACQUIRE function automatically acquires only the targets which are moving
and getting close to own ship within the range of 3 NM by Doppler calculation. Automatic Dop-
pler function will be activated when there is a target which approaches own ship with a speed
of over 3 kn.
Note: The judged speed of target is dependent on its vector towards own ship.
• The azimuth resolution can be enhanced to as high as twice with using the RezBoost function.
Note 1: RezBoost function reflects the settings of [Antenna Length] which are introduced in
page 17 and page 19.
Note 2: Refer to the Operator’s Manual for your Multi Function Display regarding the above new
functions.
• Instant ON function. This radar sensor does not have a magnetron, therefore preheating of the
magnetron is unnecessary.
• Reduced electricity emission means no need to worry about the radiation hazard.
• Magnetron-less radar means no periodic replacement of magnetron or related parts.
• The maximum display range is 72 NM in the single range mode.
• ARPA (Automatic Radar Plotting Aid) function applicable range is 24 NM at the maximum.
• Dual Range Mode has the following limitations.
- The maximum display range is 12 NM. (72 NM when single display)
- The maximum detection range is reduced a maximum of 20% compared to the single
display.

1. INSTALLATION AND WIRING
1.1 Mounting Considerations
Select a mounting location, keeping in mind the following points:
• Install the antenna unit on the hardtop, radar arch or on a mast on an appropriate
platform.
• Locate the antenna where there is a good all-round view. Where possible, there
should be no obstructions to the scanning beam such as superstructure or rigging.
Obstructions cause shadow sectors and decrease the overall performance of the
radar. The loss of performance can cause false echoes and reduce the quality of
the observed images. A mast for instance, with a diameter considerably less than
the horizontal beam width of the radiator, will cause only a small shadow sector.
However, a horizontal spreader, or cross trees in the same horizontal plane as the
antenna unit, would be a much more serious obstruction. You would need to place
the antenna unit well above or below it. Be sure there are no metallic objects near
the antenna.
• It is rarely possible to place the antenna unit where a completely clear view in all
directions is available. After fitting the antenna, determining any shadow sectors,
their angle and bearing, and their influence on the radar is recommended.
NOTICE
Do not apply paint, anti-corrosive sealant or contact
spray to coating or plastic parts of the equipment.
Those items contain organic solvents that can damage
coating and plastic parts, especially plastic connectors.

• In order to reduce electrical interference, avoid routing the power cable near other
electrical equipment on-board. Also, avoid running the cable in parallel with other
power cables.
• It is not recommended to install the antenna unit on the hardtop of a cabin. Vibra-
tions from the antenna unit will pass through the hardtop and into the cabin.
• Setup the antenna unit position on the FURUNO Multi Function Display after install-
ing the unit, referring to chapter 2. If the antenna unit position is not setup correctly,
the radar echoes on the display may not be aligned with the actual target’s bearing.
• Select a location that does not allow water to accumulate at the installation location.
• A magnetic compass will be affected if the antenna unit is too close to the compass.
Observe the compass safe distances mentioned in the SAFETY INSTRUCTIONS
to prevent interference to a magnetic compass.
• To ensure proper emission of radar waves, do not paint the radiator.
• Referring to the outline drawings at the back of this manual, allow space for main-
tenance and service.
• When this antenna unit is to be installed on a large vessel, consider the following
points:
• The supplied cable assembly runs between the antenna unit and display (or eth-
ernet HUB) and comes in lengths of 10 m, 15 m, 20 m or 30 m. Select the appro-
priate length when purchasing.
• Deposits and fumes from a funnel or other exhaust vent can adversely affect the
aerial performance and hot gases may distort the antenna unit. The antenna unit
must not be mounted where the temperature is more than 55°C (131°F).
Not recommended

Consideration for selecting a location for installation (multiple radars)
• In case multiple radars are installed on a ship, DO NOT install the DRS6A-NXT with-
in the range of the beam area emitted from other radar(s). Use the illustration below
for reference when selecting a suitable location for installation. The Solid State De-
vice (SSD) inside the DRS6A-NXT will be damaged if it is within the radar beam
emission area from other radars.
Installation with the radiotelephone equipment
• Install the open antenna away from radiocommunication antennas (SSB, VHF, In-
marasat) and GPS antennas to prevent radar interference.
• Install the open antenna away from the radiotelephone equipment so that electrical
noise does not affect the radiotelephone equipment.
Cable routing
• In order to reduce the chance of picking up electrical interference, avoid, where pos-
sible, routing the power/LAN cable and cable assembly near other electrical equip-
ment on-board. Also, avoid running the cable in parallel with other electrical cables.
• Make sure that the power/LAN cable does not run horizontally with the cable as-
sembly and it is placed away from the cables carrying radio signal and antennas.
For large vessels
• When this radar sensor is to be installed on a large vessel, consider the following
points:
• The length of the pre-attached power/LAN cable is 1 m from the open antenna to
the connector.
• Deposits and fumes from a funnel or other exhaust vent can adversely affect the
aerial performance and hot gases may distort the radiator portion. The radar sen-
sor must not be mounted where the temperature is more than 55°C (131°F).
