INSTALLATION INSTRUCTIONS
Important Safety Information
WARNING
See the Important Safety and Product Information guide in the product box for product warnings and other
important information.
Failure to install this device according to these instructions could result in personal injury, damage to the vessel
or device, or poor product performance.
The radar transmits electromagnetic energy. To avoid possible personal injury, damage to the vessel or device,
or poor product performance, ensure that the radar is installed according to the recommendations in these
instructions and that all personnel are clear of the path of the radar beam before transmitting. When properly
installed and operated, the use of this radar conforms to the requirements of ANSI/IEEE C95.1-1992 Standard
for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields.
To avoid possible personal injury, do not look directly at the antenna at close range when the radar is
transmitting. Eyes are the most sensitive part of the body to electromagnetic energy.
When connecting the power cable, do not remove the in-line fuse holder. To prevent the possibility of injury or
product damage caused by fire or overheating, the appropriate fuse must be in place as indicated in the product
specifications. Connecting the power cable without the appropriate fuse in place voids the product warranty.
CAUTION
For the best possible performance and to avoid potential injury, damage to the device, or damage to your vessel,
installation by a qualified marine installer is recommended.
Opening the device may result in personal injury and/or damage to the device. This device contains no user-
serviceable parts, and should be opened only by a Garmin
authorized service technician. Any damage resulting
®
from opening the unit by anyone other than a Garmin authorized service technician will not be covered by the
Garmin warranty.
This device should be used only as a navigational aid. Using the device for any purpose requiring precise
measurement or direction, distance, location, or topography may result in personal injury or damage to the
vessel.
To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling,
cutting, or sanding.
NOTICE
When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.

  • Page 2 Tools Needed • #2 Phillips screwdriver • 5 mm hex wrench • Drill and 15.0 mm (  in.) drill bit • 17 mm (  in.) wrench and torque wrench • A length of 3.31 mm² (12 AWG) copper wire to ground the radar housing (and voltage converter, if applicable).
  • Page 3: Mounting Considerations

    Mounting Considerations When selecting a mounting location, observe these considerations. • WARNING The radar must be mounted out of range of people, with the vertical beam width above head height. To avoid exposure to harmful radio frequency (RF) levels, the radar must not be mounted closer to people than the minimum safe distance value listed in the product specifications.
  • Page 4: Installation Procedures

    Installation Procedures Preparing the Radar Mounting Surface Before you can mount the radar, you must choose a suitable mounting location (Mounting Considerations, page 3). 1 Secure the included mounting template to the surface at the mounting location, along the bow-stern axis, as indicated on the template.

    5 Place the flat washers , lock washers , and hex nuts on the threaded rods. 6 Tighten the hex nuts to a torque of 14.7 N-m (11 lbf-ft.) to securely fasten the radar to the surface without damaging the radar or the mounting hardware. Installing the Antenna Before you can install the antenna on the pedestal, you must securely mount the pedestal (Mounting the Radar,...
  • Page 6 You must apply marine sealant to the hole after the cables are in place to ensure a waterproof seal. If you must make the routing hole in a visible location, 32 mm (1  in.) decorative cable grommets can be purchased from your local Garmin dealer, or you can go to buy.garmin.com (optional).
  • Page 7 Do not reuse any voltage converters from previous Garmin radar models, or third party voltage converters. Using any converter other than one included with the radar, or the correct converter purchased from Garmin or from your local Garmin dealer may damage the radar or prevent it from turning on.

    If a 430 xHD3 is installed using an optional voltage converter, it is capable of withstanding winds of up to 100 kn. The device withstands incidental exposure to water of up to 1 m for up to 30 min, and is protected against powerful jets of water. For more information, go to www.garmin.com/waterrating.
  • Page 14: Antenna Specifications

    Minimum Safe Operating Distances When it is transmitting, the radar should be located in a position on the vessel that is at least this far from people. IEC 60936-1, clause 3-27.1, specifies the maximum distances from the antenna at which radio frequency (RF) levels can be expected. These minimum safe distances apply for a transmitting radar with a rotating antenna, and are much larger when the antenna is not rotating.
