1. INSTALLATION
1.1 Installation Considerations
General considerations
• The radar sensor has no power switch. Therefore, it is recommended that you con-
nect the sensor to a distribution switchboard with a switch for power control.
Sensor placement
• Install the radar sensor on the hardtop, radar arch or on a mast on an appropriate
platform. (For sailboats, a “radome mount” is optionally available for fixing the sen-
sor to a mast.) Place the sensor where there is a good all-round view with, as far as
possible, no part of the ship’s superstructure or rigging intercepting the scanning
beam. Any obstruction will cause shadow and blind sectors. A mast for instance,
with a diameter considerably less than the horizontal beam width of the radiator, will
cause only a small blind sector, but a horizontal spreader or cross trees in the same
horizontal plane as the radar sensor would be a much more serious obstruction; you
would need to place the radar sensor well above or below it. Be sure there are no
metallic objects near the antenna. See illustrations below for typical placement on
a sailboat and powerboat.
NOTICE
Do not apply paint, anti-corrosive sealant or contact
spray to coating or plastic parts of the equipment.
Those items contain organic solvents that can damage
coating and plastic parts, especially plastic connectors.

• It is rarely possible to place the radar sensor 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.
• In order to reduce the chance of picking up electrical interference, avoid where pos-
sible routing the power cable near other electrical equipment on-board. Also, avoid
running the cable in parallel with other power cables.
• Select a location that does not allow water to accumulate at the base of the sensor.
• A magnetic compass will be affected if the radar sensor is too close to the compass.
Observe the compass safe distances mentioned in the SAFETY INFORMATION to
prevent interference to a magnetic compass.
• Do not paint the radome to ensure proper emission of the radar waves.
• When this radar sensor is to be installed on a large vessel, consider the following
points:
• The length of the standard supply power/LAN cable is 1 m (from radome to the
connector).
• The power/LAN cable runs between the radar sensor and display and comes in
lengths of 10 m, 15 m, 20 m or 30 m. Select the length when purchasing.
• 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 radar sen-
sor must not be mounted where the temperature is more than 55°C (131°F).
• The radar sensor should not be operated or stored in any position other than the
proper operational position (upright).
1.2 Installation of the Radar Sensor
Determine the suitability of the mounting location BEFORE permanently mounting the
sensor. Incoming and outgoing signals may overlap one another depending on the
shape of the vessel, preventing communication between the radar and display. Set the
sensor on the selected location and connect the sensor to the distribution switchboard
and display unit. Turn on the sensor and the display unit. Check that the picture is up-
dated with each sweep on the display unit. Some trial and error may be necessary to
find a suitable location.
Required tools for installation
Prepare the tools shown below.
• A wrench for M10 bolts
• An electric drill with I11 mm (0.43”) drill bit

1. INSTALLATION

Installation on a platform
Follow the instructions below to install the sensor on a platform.
Note: The outer diameter of the small flat washer is the same size as the bolt hole. If
the radome is put upside down with only the small flat washer and hex bolt in place,
the hex bolt and flat washer may protrude into the radome and damage the RT unit.
For this reason, DO NOT put the radome upside down when carrying the radome.
If it is necessary to transport the radome, be sure the large flat washers are in place
before transporting, to prevent damage to the RT unit.

3. MAINTENANCE, TROUBLE-
SHOOTING
3.1 Maintenance
Regular maintenance is important for good performance. Check the points mentioned
below every 3 to 6 months to keep the radar sensor in good working order. Observe
the safety instructions at the front of this manual when working on the mast.
3.2 Replacement of Fuse
The 5A fuse (Type: FRU-2P5S-FU-5A-A, Code No.: 000-168-869-10) in the fuse hold-
er on the power/LAN cable protects the radar sensor from overcurrent and equipment
fault. If you cannot turn on the power, check the fuse to see if it has blown. If the fuse
has blown, find the reason before you replace the fuse. If the fuse blows again after
the replacement, contact your dealer for advice.
Check point Action
Fixing bolts
• Corrosion
• If they are tightly fastened
• Replace corroded bolts.
• Tighten loosened bolts.
• Coat new bolts with marine sealant.
Radome
• Cracks
• Foreign material
If a crack is found, repair it temporarily with a small
amount of sealing compound or adhesive. Bring the unit
to your dealer for permanent repairs.
Foreign material on the radome can cause a consider-
able drop in sensitivity. Remove foreign material with a
freshwater-moistened cloth. Do not use commercial
cleaners to clean the sensor; they can remove paint and
markings or deform the plastic.
WARNING
Use the proper fuse.
Use of the wrong fuse can damage the equip-
ment or cause fire.

tion. If you cannot restore normal operation, contact your dealer for advice.
3.4 Replacement of Magnetron
The life expectancy of the magnetron is approx. 5,000 hours (including standby). The
effectiveness of the magnetron decreases over time, causing lower-than-normal sig-
nal strength and loss of echoes. If you feel the signal strength is low, contact your deal-
er about replacement of the magnetron.
Trouble Remedy
The power cannot be turned on. • Check if the power/LAN cable is connected to
the power source and the power source is on.
• Check the power cable for damage.
• Check if the fuse has blown.
Picture is not updated or the picture
freezes.
• Check antenna cable.
• If the picture freezes, reboot the display unit.
Marks and characters appear on
the display, but echoes do not ap-
pear.
Check that the antenna cable is fastened.
You changed the range, but the ra-
dar picture does not change.
• Try to zoom in or out the radar display.
• Turn the power off and on.
Signal strength is too low. Have a technician check the magnetron.
