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 trans-
mitting antenna at a close distance.
Distances at which RF radiation levels of
100 and 10 W/m
2
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.

SAFETY INSTRUCTIONS
Do not open the equipment
unless totally familiar with
electrical circuits and
service manual.
Only qualified personnel
should work inside the
equipment.
Wear a safety belt and hard
hat when working on the
antenna unit.
Serious injury or death can
result if someone falls from
the radar mast.
WARNING
Construct a suitable service platform
from which to install the antenna unit.
Serious injury or death can result if some-
one falls from the radar mast.
Turn off the power at the mains switch-
board before beginning the installation.
Fire, electrical shock or serious injury can
result if the power is left on or is applied
while the equipment is being installed.

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.

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.

This method requires removal of the RF unit in the antenna unit to access inside fixing
holes. Use hex head bolts, flat washers, spring washers and nuts (local supply) to mount
the antenna unit, confirming length of bolts.
1. Unfasten four antenna bolts on the cover to open the antenna unit.
2. Unfasten four screws on the RTB cover to remove it.
3. Unplug connector J827 and J834 on the RTB board.
4. Separate upper chassis from lower chassis by removing two hex head bolts (M8x25).
5. Remove RF unit by unfastening four hex head bolts.

of bolts with silicone sealant. Cut a slit in the rubber bushing and insert bolt into the
bushing. Do not use seal washers.
9. Reassemble RF unit, cover and chassis.
10.Set four knob caps (supplied) into outside fixing holes.
11.Do steps 6-8 in “Outside fixing holes”.

Connecting 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.

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.
