Warnings
HIGH VOLTAGE WARNING! Dangerously high voltages are present within the scanner unit. There
are no internal connections or adjustments necessary for installation. The cover should be removed
only by a qualified radar service technician. Technicians must exercise extreme care when working
inside the unit. Always remove power before removing the cover. Some capacitors may take several
minutes to discharge, even after switching off the radar. Before touching the magnetron or any high
voltage components, ground them with a clip lead.
CAUTION! Installation and radar tuning should only be performed by a qualified radar service
technician.
DANGER: MICROWAVE RADIATION HAZARD! The microwave energy radiated by a radar antenna
is harmful to humans, especially to one’s eyes. Never look directly into an open waveguide or into
the path of radiation from an enclosed antenna. Radar and other radio frequency radiation can upset
cardiac pacemakers. If someone with a cardiac pacemaker suspects abnormal operation,
immediately turn off the equipment and move the person away from the antenna. Turn off the radar
whenever it is necessary to work on the antenna unit or on other equipment in the beam of the radar.
WARNING! How to interpret the radar display is not included in this manual. The captain is responsible
for the proper use of radar and the safety of the vessel and its passengers.
WARNING! This device should not be used as a navigational aid to prevent collision, grounding, boat
damage, or personal injury. When the boat is moving, water depth may change too quickly to allow
time for you to react. Always operate the boat at very slow speeds if you suspect shallow water or
submerged objects.
WARNING! The electronic chart in your Humminbird® unit is an aid to navigation designed to
facilitate the use of authorized government charts, not to replace them. Only official government
charts and notices to mariners contain all of the current information needed for the safety of

The word “radar” is an acronym for “Radio Detecting And Ranging.” A radio transmitter sends a quick
microwave pulse, and then a receiver listens for that signal’s echo when it is bounced back from something
in its path. The returning signal is processed by a computer to determine its relative distance, position, and
bearing. This information is graphically displayed on a view for you to see. Other boats or ships, navigational
markers, and landmasses are referred to as targets.
By knowing how long it takes for a signal to return, the distance to a target can be determined. As the radar
antenna scans through a 360-degree rotation, it can show where the target is relative to your position. By
repeated scans, you can see which direction another boat is moving. How a target is displayed on the screen
depends on the target’s height and size as well as its material and shape.
Boat and Surrounding Targets Radar Display
How radar will perform is mostly determined by the antenna
or scanner. Increasing the size of the antenna improves
long-range performance and target discrimination, or the
ability to distinguish two separate targets at a distance. The
critical factors are the antenna’s beam width and side lobe
level.Typically, a radar antenna will radiate a tightly focused
beam from the front of the array. The longer the antenna
array is, the narrower the beam width will be. Additionally,
it will also emit smaller amounts of energy to each side. The
lower the side lobe level, the less the effect of a false echo.
WARNING!

and the safety of the vessel and its passengers.

Choose the Mounting Location
It is important to consider the following information when installing the scanner on the boat. Also, see Adjust
for Obstacles for more information.
WARNING!
Do NOT install the radar in a location that exposes passengersand crew to the radar beam. Do NOT mount
the radar where it could radiate on any person.
CAUTION! Working at higher elevations may become necessary while installing the scanner unit. Observe safety measures
and take sufficient precautions to avoid personal injury or damage to the equipment.
Center Line: The scanner unit should be mounted on
the center line of your boat in a location that has an
Center line
of boat
unobstructed view forward and is as clear as possible
the rest of the way around the unit.
Height: Choose a location as high as practical to
improve maximum range; however, keep in mind that
minimum range objects may be overlooked if mounted
too high.
Unobstructed View: Position the unit forward of large
structures and exhaust stacks. Large structures or
stacks cause blind spots. Contamination from engine
exhaust on the scanner housing reduces radar
performance.
Installation
• Antennas for GPS, radio communication, or other
equipment should not be located in the radar
beam.
• Use non-metallic extension poles to move the
active area of antennas above the radar beam.

Surface: The mounting surface must be flat and approximately parallel with the boat’s water line.
3/8”-1/2”
3/8”-1/2”
Surface Thickness: The mounting surface must support the weight of the scanner. The
recommended surface thickness is 3/8 to 1/2 in (9.5 mm to 13 mm). If the mounting surface is thin,
a doubler should be added. If it is thicker than recommended, longer bolts must be purchased
separately.
CAUTION! The scanner will be damaged if the bolts protrude more than 1/2 inch (13 mm).
Access: Access to the under side is required for installation of the mounting bolts.
Cable Routing: Test the cable route from the scanner to the control head and power location. Avoid
routing the interconnecting cable through areas of possible damage, from moving objects, machinery,
exposure to chemicals, or high temperature. See Installation: Connect Power for more information.

Obstacles in the radar beam (such as a ship mast) can cause shadow zones, which will prevent you from
seeing targets behind the obstacle. Use the following sections to ensure a clear view for the radar.
Shifting from the Center Line
Shift the scanner position from the center line to the starboard side of the boat to move shadow zones to
the port side. This makes it possible to keep a clear view to the bow. The distance to be shifted can be
calculated using the following equation:
Ls=0.4R+D/2 [m] (when R<15m)
Ls=0.025R+D/2 [m] (when R>=15m)
where: Ls = distance to be shifted from center line
D = diameter of obstacle on center line
R = distance from scanner to obstacle

Obtaining Sufficient Dip Angle
Raise the scanner position so that there is a sufficient dip angle available between the line of sight from the
scanner to the obstacle and the horizontal line. By raising the dip angle 5°, it is possible to prevent mid- and
long-distance shadow zones. Don’t adjust the dip angle too high since the radar cannot detect objects below
the sight line.
