Important Safety Information
See the Important Safety and Product Information guide in the
product box for product warnings and other important
The radar transmits electromagnetic energy. 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.
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 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. Do not
attempt to use the device for any purpose requiring precise
measurement of direction, distance, location, or topography.
Always wear safety goggles, ear protection, and a dust mask
when drilling, cutting, or sanding.
When drilling or cutting, always check what is on the opposite
side of the surface.

Mounting Considerations
To complete the installation, you need the appropriate fasteners,
tools, and mounts. These items are available at most marine
It is highly recommended that the device is mounted out of
range of personnel, with the horizontal beam width above
head height.
IEC 60936-1, clause 3-27.1, states maximum distances from
the antenna at which radio frequency (RF) levels can be

100 W/m squared = 91 cm (36 in.)
10 W/m squared = 289 cm (114 in.)

The device should be mounted high above the ship’s keel
line with minimal blockage between the vessel and the radar
beam. Obstructions may cause blind and shadow sectors, or
generate false echoes. The higher the installation position,
the farther the radome can detect targets.
The device should be mounted on a flat surface or a platform
that is parallel to the vessel's water line and is sturdy enough
to support the device's weight. The weight for each model is
listed in the product specifications.
Most radar beams spread vertically 12.5° above
and 12.5°
the radome's radiating element. On vessels with
higher bow angles at cruise speed, the installation angle can
be lowered to point the beam slightly downward to the
waterline while at rest. Use shims if necessary.
The radome has two mounting options when installed on a
standard marine mount. One mounting option is closer to the
