Important Safety Information
WARNING
See the
Important Safety and Product Information
guide in the
product box for product warnings and other important
information.
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.
CAUTION
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.
NOTICE
When drilling or cutting, always check what is on the opposite
side of the surface.
CAUTION
Opening the pedestal 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 to the device resulting from
opening the unit by anyone other than a Garmin authorized
service technician will not be covered by the Garmin warranty.

Updating the Device Software
Before you can update the software, you must obtain a
software-update memory card or load the latest software onto a
memory card.
1
Turn on the chartplotter.
2
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.
3
Follow the on-screen instructions.
4
Wait several minutes while the software update process
completes.
5
When prompted, leave the memory card in place and restart
the chartplotter manually.
6
Remove the memory card.
NOTE:
If the memory card is removed before the device
restarts fully, the software update is not complete.
Mounting Considerations
To complete the installation, you need the appropriate fasteners,
tools, and mounts. These items are available at most marine
dealers.
• It is highly recommended that the device is mounted out of
range of personnel, with the horizontal beam width above
head height. To avoid exposure to harmful radio frequency
(RF) levels, the device should not be mounted closer to
people than the maximum safe distance value listed in the
product specifications.
• 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
À
and 12.5°
below
Á
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.
