SAFETY INSTRUCTIONS
WARNING
Do not open the equipment
unless totally familiar with
electrical circuits and
service manual.
ELECTRICAL
SHOCK
HAZARD
Construct a suitable service platform
from which to install the antenna unit.
Serious injury or death can result if someone falls from the radar mast.
Turn off the power at the mains switchboard 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.
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
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/m
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.

SYSTEM CONFIGURATIONS
All NavNet products incorporate a "network circuit board" to integrate each NavNet product
on board through an optional LAN cable (Ethernet 10BASE-T). Each NavNet product is
assigned an IP address to enable transfer of images between other NavNet products. For
example, video plotter pictures can be transferred to a radar and vice versa. Pictures
received via the NavNet may be adjusted at the receiving end.
The number of processor units which may be installed depends on the number of network
sounder connected. For a system incorporating three or more products, a "hub" is required
to process data.
For one network sounder: one radar and three plotters, or four plotters
For two network sounder: one radar and two plotters, or four plotters

1. MOUNTING
1.1 Mounting the Control Unit
The control unit can be installed on a desktop or flush mounted in a console or panel. For
flush mounting, the optional flush mount kit is required.
When selecting a mounting location for the control unit keep the following in mind:
Keep the control unit out of direct sunlight.
•
The temperature and humidity of 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 motor,
•
generator.
For maintenance and checking purposes, leave sufficient space at the sides and rear of
•
the unit and leave slack in cables.
A magnetic compass will be affected if the control unit is placed too close to the magnetic
•
compass. Observe the following compass safe distances to prevent disturbance to the
magnetic compass.
Standard compass: 0.45 m
Steering compass: 0.30 m

1.2 Mounting the Processor Unit
The unit can be mounted on th e dec k , a desktop or on a bulkhead. Select a mounting
locati on c ons idering the points below.
• Locate the unit out of direct s unlight.
• Select a location where temper ature and humidity are moderate and stabl e.
• Consider the length of the cable c onnected am ong the proces s or unit, antenna unit (or
power supply unit) and c ontrol unit.
• For mounting on a bulkhead, be sure the mounting locati on is strong enough to support
the unit (4.1kg) under the pitching and r olling norm ally encounter ed on the vessel.
• Leave sufficient space ar ound the unit for maintenance and servic ing. Recomme nded
maintenance space app ears in the outl ine drawing at t he bac k of this manual.
• A magnetic compass will be affected i f t he pr oc es s or unit is placed too clos e to the
magneti c c ompas s . Observe the follow ing compass saf e distances to pr event dis t ur bance
to the magnetic compass.
Standard compass: 1.75 m
Steering compass: 1.10 m
Tableto p or deck mounting: Fasten wit h four tapping screws.
Bulkhead mounting: Mark four fixing hol e pos itions on the bulkhead. S c r ew in two tappi ng
screw s at l ower fixing positions, leavi ng 5 m m protruding. Set the proces sor unit to the
screw s and s cr ew in two tappi ng s c rews at upper positions. Tighten all screws .

1.3 Mounting the Antenna Unit of MODEL1823C-BB
Mounting considerations
When selecting a mounting location for the antenna unit keep in mind the following points.
Install the antenna unit on the hardtop, radar arch or on a mast on an appropriate
•
platform. (F or sailboats, a mounting bracket is optionally available.) It should be placed
where there is a good all-round view with, as far as possible, no part of t he 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 width of the antenna unit, will cause only a small blind sector. However, a horizontal
spreader or crosstrees in the same horizontal plane would be a much m ore serious
obstruction; place the antenna unit well above or below it.

routing the antenna cable near other electrical equipm ent onboard. Also avoid running
the cable in parallel with power cables.
The compass safe distance of 1.25 meters (standard compass) and 0.85 meters (steering

Mounting the antenna unit of MODEL1823C-BB
1. Remove mounting hardware at the bottom of the antenna unit; four each of hex. bolts
(M10X20), spring washers and flat washers. Save mounting hardware to use it to fix the
antenna unit to the mounting platform later on.

2. Construct a platform (wood, steel*, or aluminum) of 5-10 mm (recommended dim ension)
in thickness referring to the outline drawing at back of this manual. A mounting bracket
for mounting the ant enna unit on a sailboat mast is optionally available. (Refer to page
1-11.) Fasten the platform to the mounting location. Next, position the mounting base on
the platform so the cable entrance faces the stern direction.
*: For steel platform take appropriate measures to prevent corrosion.
Note: When drilling holes in the platform, be sure they are parallel with the fore and aft
line.
3. Using the hex bolts, flat washers and spring washers removed at step 1, fasten the
mounting base to the platform. The torque should be between 19.6-24.5 N•m.
Note: Longer hex bolts (M10X25) are supplied with the installation materials. Use them
instead of the hex bolts removed earlier if the mounting platform thickness is
5–10 mm.

1.5 Mounting the Antenna Unit of
MODEL1933C-BB/1943C-BB/1953C-BB
Mounting considerations
• The antenna unit is generally install ed either on top of the wheelhouse or on the radar
mast on a suitable pl atform. Locate the antenna unit where there is a good all-round vi ew.
Any obstruction will cause shadow and blind sectors . A mast for instanc e, with a diameter
considerabl y less t han the width of the radiator, will cause only a small blind sector, but a
horizontal spreader or cr os s trees in the sam e hor izontal plane as the ant enna unit would
be a much more serious obs truction; you would need to pl ac e the antenna unit well
above or below it.
• It is rarely possible to pl ac e the antenna unit where a completely clear view in all
directions is avail able. Thus, y ou s hould determi ne the angular widt h and r elative bearing
of any shadow sectors for their influence on t he r adar at the firs t opportunit y after fitting.
• To lessen the chance of pick ing up electr ical interference, avoid where possible routing
the signal c able near other onboard el ec trical 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 the
magnetic com pass. Obser ve the following compass safe distances to prevent deviation of
a magnetic com pass: Standar d c om pass, 1.00 m, Steering compass, 0.80 m (1953C- B B :
0.75 m).
• Do not paint the radiator aperture, to ensure proper emission of the radar waves.
a) When this radar is to be installed on larger vessels, consider the following points:
The signal cable run between the antenna and the processor units comes in lengths of
10 m, 15 m, 20 m and 30 m.
b) 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 show n in the figur e below, the antenna unit may be installed on the bridge, on a comm on
mast or on the radar m as t.
(a) On bridge
(b) Common mast
(c) Radar mast
