SHOCK
HAZARD
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.
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.
CAUTION
Ground the equipment to
prevent electrical shock and
mutual interference.
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 produc t
on board through an optional LAN cable (Ethernet 10BASE-T). Each NavNet product is
assigned an IP addr es s to enable transfer of images between other NavNet products. For
example, video plotter pictures can be t r ans ferr ed to a radar and vi c e v er s a. Pictures
received vi a t he NavNet may be adjusted at t he r ec eiving end.
The number of display units which may be ins talled depends on the number of netw or k
sounder con nec ted. For a s ystem incorpor ating t hr ee or m ore products, a “hub” is required
to process data.
For one network sounder: one radar an d three plot ters, or four plotters
For two network sounder: one r adar and two plotters, or f our plotters

1. MOUNTING
1.1 Installation of Display Unit
The display unit can be installed on a tabletop, on the overhead or flush mounted in a
console or panel.
Tabletop, overhead mounting method
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 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 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 display unit is placed too close the magnetic
•
compass. Observe the following compass safe distances to prevent disturbance to the
magnetic compass.
Standard compass: 0.60 m
Steering compass: 0.40 m

1.1.1 Mounting procedure
Tabletop, overhead mounting
Follow the procedure below to mount the display unit on a tabletop or the overhead.
1. Fix the hanger by four tapping screw (5x20).
2. Screw knob bolts in display unit, set it to hanger, and tighten knob bolts.
3. Attach hard cover to protect LCD.

Flush mounting
Note: Use supplied six pan head screws when the thickness of the bulkhead is from 11 to
14 mm. For bulkhead which exceeds 14 mm in thickness the length of the pan head
screws should be bulkhead thickness (A) plus 7.8±2 mm. Also the length of B should
be max. 8 mm.

1.2 Mounting of Antenna Unit for MODEL1833C
1.2.1 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.
Antenna unit

Typical antenna unit placement on sailboat and powerboat
In order to minim ize the chance of picking up electrical interference, avoid where possible
•
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 0.90 meters (standard compass) and 0.70 meters (steering
•
compass) should be observed to prevent deviation of the magnetic compass.

1.2.2 Mounting antenna unit of MODEL 1833C
1. Open the antenna unit packing box carefully.
2. Unbolt the four bolts at the base of t he radome to remove the radome cover.
Radome cover
Antenna unit
The mounting surface must be parallel with the waterline and provided with five holes (four
fixing holes and one cable entry) whose dimensions are shown in the outline drawing
attached at the end of this manual.
The unit is adjusted so a target echo returned from the bow direction will be shown on the
zero degree (heading line) position on the screen. W hen drilling holes, be sure they are
parallel with the fore and aft line.
3. Prepare a platform of 5 to 10 millimeters in thickness for the antenna unit.
A mounting bracket for mounting the antenna unit on a sailboat mast is optionally
available. (Refer to page 1-9.) Find the cable entry on the radome base. Next, position
the radome base so the cable entry faces the stern direction. This alignment must be as
accurate as possible.

1.3 Mounting of Antenna Unit for MODEL1933C/1943C/1953C
1.3.1 Mounting considerations
The antenna unit is generally installed either on top of the wheelhouse or on the radar
•
mast on a suitable platf orm. 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, keep the antenna unit from its antenna
•
more than two meters to prevent the int erference to the direction finder.
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 the magnet
•
compass. Observe the following compass safe distances to prevent deviation of a
magnetic compass: Standard compass, 1.00 m, Steering compass, 0. 80 m (1953C: 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 t he following points:
The signal cable run between the antenna and the display comes in lengths of 10 m, 15
m, 20 m and 30 m. Whatever length is used it must be unbroken; namely, no splicing
allowed.
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 shown in the figure below, the antenna unit may be installed on the bridge, on a common
mast or on the radar mast.
