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.

1. MOUNTING
1.1 Antenna Unit
Mounting considerations
• 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 horizontal beamwidth 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.
• 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 the antenna unit is placed too close to it. Observe
the compass safe distances mentioned in the SAFETY INSTRUCTIONS to prevent
interference to a magnetic compass.
• 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 units comes in lengths of
10 m, 15 m, 20 m and 30 m.
• 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.
As shown in the figure below, the antenna unit may be installed on the bridge, on a common
mast or on the radar mast.

Mounting procedure
Referring to the outline drawing at the back of this manual, drill five holes in the mounting
platform: four holes of 15 mm diameter for fixing the antenna unit and one hole of 25-30 mm
diameter for the signal cable.
Fastenin g t he radiator to the radiat o r bracket
For your reference, the antenna installation materials list appears in the packing list at the
back of this manual.
1. Remove the radiator cap from the radiator bracket.
2. Coat contacting surface between the antenna radiator and the radiator bracket with
silicone sealant as shown in the figure below.

Connecti n g the signal cable
Only the signal cable runs from the display unit (power supply unit in case of FR-8252) to
the antenna unit. In order to minimize 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. Pass the cable through the hole and apply
sealing compound around the hole for waterproofing.
• Fabricating the signal cable
This type of signal cable is used with other models of radar. For this model, the following
fabrication is required.
1. Remove shrink tubing from the signal cable.
Remove shrink tubing.
2. Remove vinyl sheath approx. 50 mm.

1.2 Display Unit
The display unit can be mounted on a tabletop, on the overhead or flush mounted in a
console or panel.
Mounting considerations
When selecting a mounting location for the display unit, keep the following in mind:
• Keep the display unit out of direct sunlight.
• The temperature and humidity at the mounting location should be moderate and stable.
• Locate the unit away from exhaust pipes and vents.
• The mounting location should be well ventilated.
• Mount the unit where shock and vibration are minimal.
• Keep the unit away from electromagnetic field generating equipment such as motors and
generators.
• For maintenance and checking purposes, leave sufficient space at the sides and rear of
the unit and leave slack in cables. Minimum recommended space is shown in the outline
drawing for the display unit.
• A magnetic compass will be affected if the display unit is placed too close to it. Observe
the compass safe distances shown in the SAFETY INSTRUCTIONS to prevent
disturbance to the magnetic compass.
