Important Safety Information
Failure to follow these warnings, cautions, and notices could result in personal injury, damage to the vessel or
device, or poor product performance.
See the Important Safety and Product Information guide in the product box for product warnings and other
important information.
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. In addition, connecting the power cable without the appropriate fuse in place voids the product
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.
Always wear safety goggles, ear protection, and a dust mask when drilling, cutting, or sanding.
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
from opening the unit by anyone other than a Garmin authorized service technician will not be covered by the
Garmin warranty.
When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.

NOTICE When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.
  • Page 2: Mounting Considerations

    The weight for each model and antenna is listed in the product specifications. • The device must be mounted in a location where it can be connected to power, water ground, and the Garmin Marine Network (Wiring and Connection Considerations, page 7).
  • Page 3: 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 2). 1 Secure the included mounting template to the surface at the mounting location, along the bow-stern axis, as indicated on the template.
  • Page 4 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.
  • Page 5: Installing The Antenna

    Installing the Antenna Before you can install the antenna on the radar, you must securely mount the pedestal (Mounting the Radar, page 3). 1 Remove the protective cover from the waveguide on the top of the pedestal. 2 Align the waveguide on the pedestal with the socket on the bottom of the antenna , and slide the antenna onto the pedestal.
  • Page 6 3 Secure the antenna to the pedestal by tightening the captive hex bolts under the antenna arm. 4 Tighten the hex bolts to a torque of 7.9 N-m (6 lbf-ft.) to fasten the antenna to the pedestal without damaging the antenna or the mounting hardware.
  • Page 7 When installing the cables, you should observe these considerations. • Cutting the Garmin Marine Network cable is not recommended, but a field install kit can be purchased from Garmin or a Garmin dealer if you must cut the network cable.

    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.
