SAFETY INSTRUCTIONS
WARNING
Radio Frequency Radiation Hazard
The radar antenna emits electromagnetic radio frequency (RF) energy which can be
harmful, particularly to your eyes. Never look directly into the antenna aperture from a
close distance while the radar is in operation or expose yourself to the transmitting
antenna at a close distance.
Distances at which RF radiation levels of 100 and 10 W/m2 exist are given in the table
below.
Note: If the antenna unit is installed at a close distance in front of the wheel house,
your administration may require halt of transmission within a certain sector of antenna
revolution. This is possible  Ask your FURUNO representative or dealer to provide
this feature.

MOUNTING
1.1 Mounting Methods for Antenna Unit
• The antenna unit is generally installed either on top of the wheelhouse or on
the radar mast on a suitable platform. Locate the antenna unit where there is a
good all-round view. Any obstruction will cause shadow and blind sectors.
A mast for instance, with a diameter considerably less than the width of the
radiator, will cause only a small blind sector, but a horizontal spreader or
crosstrees in the same horizontal plane as the antenna unit would be a much
more serious obstruction; you would need to place the antenna unit well above
or below it.
• It is rarely possible to place the antenna unit where a completely clear view in
all directions is available. Thus, you should determine the angular width and
relative bearing of any shadow sectors for their influence on the radar at the
first opportunity after fitting.
• If you have a radio direction finder on your boat, locate its antenna clear of the
antenna unit to prevent interference to the direction finder. A separation of
more than two meters is recommended.
• To lessen the chance of picking up electrical interference, avoid where possible
routing the signal cable near other onboard electrical equipment. Also avoid
running the cable in parallel with power cables.
• A magnetic compass will be affected if placed too close to the antenna unit.
Observe the following compass safe distances to prevent deviation of a
magnetic compass: Standard compass, 1.00 m, Steering compass, 0.75 m.
• Do not paint the radiator aperture, to ensure proper emission of the radar
waves.
• When this radar is to be installed on larger vessels, consider the following
points:
! The signal cable run between the antenna and the display comes in lengths
of 10 m (standard), 15 m, 20 m and 30 m. Whatever length is used it must
be unbroken; namely, no splicing allowed.
! Deposits and fumes from a funnel or other exhaust vent can adversely
affect the aerial performance and hot gases may distort the radiator portion.
The antenna unit must not be mounted where the temperature is more than
70°C.

1.6 Mounting Methods for Display Unit
When selecting a mounting location for the display unit keep in mind the following
points.
• The display unit is designed and constructed to be splashproof, thus it can be
installed outdoors. You can even hose it down after a day’s outing. If it is to be
installed outdoors, we recommend installing it an enclosed cabinet, for
maximum protection against the marine environment.
• The temperature and humidity of the mounting location should be stable and
moderate. No LCD can provide adequate contrast if the ambient temperature is
too extreme.
• The display unit consumes only a moderate amount of power, so there is no
need for forced air ventilation. However, you should provide adequate space
behind and around the unit to permit circulation of air and to provide convenient
access to the rear connectors.
• Even though the picture is quite legible even in bright sunlight, keep the display
unit out of direct sunlight or at least shaded because of heat that can build up
inside the cabinet.
• Locate the display unit in a position where you can view and operate it
conveniently but where there is no danger of salt or fresh water spray or
immersion.
• The orientation of the display unit should be so the radar screen is viewed
while the operator is facing in the direction of the bow. This makes
determination of your position much easier.
• Make sure you allow enough clearance both to get to the connectors behind
the unit and to allow you to get your hands in on both sides to loosen or tighten
the mounting knobs. Make sure you leave at least a foot or so of “service loop”
of cables behind the unit so it can be pulled forward for servicing or easy
removal of the connectors.
• A magnetic compass will be affected if placed too close to the display unit.
Observe the minimum compass safe distances to prevent deviation of a
magnetic compass: standard compass, 0.7 meters, and steering compass, 0.5
meters.

3.1 Checking magnetron heater voltage
Magnetron heater voltage is formed on the MD Board (03P9235) of the antenna
unit, and is preadjusted at the factory for use with any length of signal cable.
Therefore no adjustment is required. However, check magnetron heater voltage
as follows:
1. Turn on the radar and leave it in stand-by.
2. Open the antenna cover.
3. Unfasten four screws to remove the RF section cover.
DANGER

3.5 Heading Alignment
You have mounted the antenna unit facing straight ahead in the direction of the
bow. Therefore, a small but conspicuous target dead ahead visually should
appear on the heading mark (zero degrees).
In practice, you will probably observe some small error on the display because of
the difficulty in achieving accurate initial positioning of the antenna unit. The
following adjustment will compensate for this error, 360 degrees.
1. Identify a suitable target (for example, ship or buoy) at a range between 1/8 to
1/4 miles, preferably near the heading mark. To minimize error, keep echoes
in the outer half of the picture by changing the range.
2. Display the Installation Setup 2 menu.

3. ADJUSTMENT
3.6 Sweep Timing
This adjustment ensures proper radar performance, especially on short ranges.
The radar measures the time required for a transmitted echo to travel to the
target and return to the source. The received echo appears on the display based
on this time. Thus, at the instant the transmitter is fired, the sweep should start
from the center of the display (sometimes called sweep origin.)
A trigger pulse generated in the display unit goes to the antenna unit through the
signal cable to trigger the transmitter (magnetron). The time taken by the signal to
travel up to the antenna unit varies, depending largely on the length of signal
cable. During this period the display unit should wait before starting the sweep.
When the display unit is not adjusted correctly, the echoes from a straight local
object (for example, a harbor wall or straight pier) will not appear with straight
edges  namely, they will be seen as “pushed out” or “pulled in” near the picture
center. The range of objects will also be incorrectly shown.

(2) Target pushed (3) Target pushed

Figure 3-8 Examples of improper and correct sweep timings
1. Display the Installation Setup 2 menu and select Adjust Sweep Timing by
pressing omnipad.
2. Transmit the radar on the shortest range.
3. Visually select a straight echo (harbor wall, straight pier).
4. While looking at the target selected above, press omnipad at the 9 o’clock or 3
o’clock position to straighten the target.
5. Press the [ENT] key.
6. After adjustment press the [MENU] key and turn off the power to close the
installation menu.
