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/m2exist 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. This is possible - Ask
your FURUNO representative or dealer to
provide this feature.

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.

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 display units which may be installed depends on the number of network
sounders connected. For a system incorporating three or more NavNet products, a “hub” is
required to process data.
For one network sounder: one radar and three plotters, or four plotters
For two network sounders: one radar and two plotters, or four plotters

1. MOUNTING
1.1 Mounting the Display Unit
The display unit can be mounted on a tabletop, on the overhead or flush mounted in a
console or panel.
Hard Cover
Table Top
Overhead
Tabletop, overhead mounting method
1.1.1 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.

1-2
1.1.2 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 using four tapping screws (5x20).
2. Screw knob bolts in display unit, set it to the hanger, and tighten the knob bolts.
3. Attach the hard cover to protect the LCD.

Note: For the overhead mounting, reinforce the mounting location and secure the hanger,
with bolts, nuts and washers (local supply).

1-3
Flush mounting
Note: Use supplied 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±1.2 mm. Also the length of B
should be max. 8 mm.

Note: When installing the display unit in a panel, attach the vinyl tube (ø6, local supply) to
the drain hole to allow moisture to escape. Then, fasten the tube to the drain hole with
a cable tie.

1.2 Mounting the Antenna Unit of MODEL1824C
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. (For 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 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 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 more serious
obstruction; place the antenna unit well above or below it.
Antenna unit

Typical antenna unit placement on sailboat and powerboat
• In order to minimize the chance of picking up electrical interference, avoid where possible
routing the antenna cable near other electrical equipment onboard. Also avoid running the
cable in parallel with power cables.
• Observe the compass safe distances mentioned in the SAFETY INSTRUCTIONS to
prevent interference to a magnetic compass.

1-5
1.2.2 Mounting procedure
1. Remove the mounting hardware from the bottom of the antenna unit: four each of hex
bolts (M10X20), spring washers and flat washers. Save the 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 dimension)
in thickness referring to the outline drawing at back of this manual. 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.

4. The mounting base is fitted with a snap holder, which may be used to hang the cover
after removal. Use the hole next to a screw hole inside the cover to hang it.
a) Unfasten the snap assy. with the string attached at the holder in the mounting base.
b) Unwind the string.
c) Attach the snap to a screw hole on the inside of the cover.
Note: Do not hang any other objects with the snap.
Remove and discard
