How to discard this product
Discard this product according to local regulations for the disposal of industrial waste. For
disposal in the USA, see the homepage of the Electronics Industries Alliance
(http://www.eiae.org/) for the correct method of disposal.
How to discard a used battery
Some FURUNO products have a battery(ies). To see if your product has a battery, see the
chapter on Maintenance. Follow the instructions below if a battery is used. Tape the + and -
terminals of battery before disposal to prevent fire, heat generation caused by short circuit.
In the European Union
The crossed-out trash can symbol indicates that all types of
batteries must not be discarded in standard trash, or at a trash site.
Take the used batteries to a battery collection site according to your
national legislation and the Batteries Directive 2006/66/EU.
In the USA
The Mobius loop symbol (three chasing arrows) indicates that
Ni-Cd and lead-acid rechargeable batteries must be recycled.
Take the used batteries to a battery collection site according to
local laws.
In the other countries
There are no international standards for the battery recycle symbol. The number of symbols
can increase when the other countries make their own recycling symbols in the future.

SAFETY INSTRUCTIONS
WARNING
ELECTRICAL SHOCK HAZARD
Do not open the equipment.
Only qualified personnel
should work inside the
equipment.
Turn off the radar power
switch before servicing the
antenna unit. Post a warn-
ing sign near the switch
indicating it should not be
turned on while the antenna
unit is being serviced.
Prevent the potential risk of
being struck by the rotating
antenna and exposure to
RF radiation hazard.
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 antenna mast.
Do not disassemble or modify the
equipment.
Fire, electrical shock or serious injury can
result.
Turn off the power immediately if water
leaks into the equipment or the equip-
ment is emitting smoke or fire.
Continued use of the equipment can cause
fire or electrical shock.
Use the proper fuse.
Fuse rating is shown on the power cable.
Use of a wrong fuse can result in damage
to the equipment.
Keep heater away from equipment.
Heat can alter equipment shape and melt
the power cord, which can cause fire or
electrical shock.
A warning label is attached to the
equipment. Do not remove the label.
If the label is missing or damaged,
contact a FURUNO agent or dealer.
WARNING
To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.
Name: Warning Label (1)
Type: 86-003-1011-0
Code No.: 100-236-230
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. This is possible - Ask
your FURUNO representative or dealer to
provide this feature.

FOREWORD
A Word to the Owner of the Model 1724C/1734C Series
Marine Radar, GD-1720C Color Video Plotter
FURUNO Electric Company thanks you for purchasing the Model 1724C/1734C Series
Marine Radar, GD-1720C Color Video Plotter. We are confident you will discover why the
FURUNO name has become synonymous with quality and reliability.
For over 60 years FURUNO Electric Company has enjoyed an enviable reputation for
quality and reliability throughout the world. This dedication to excellence is furthered by our
extensive global network of agents and dealers.
Your equipment is designed and constructed to meet the rigorous demands of the marine
environment. However, no machine can perform its intended function unless properly
installed and maintained. Please carefully read and follow the operation and maintenance
procedures set forth in this manual.
We would appreciate feedback from you, the end-user, about whether we are achieving our
purposes.
Thank you for considering and purchasing FURUNO.
Features
The 1724C/1734C Radar Series and the GD-1720C Video Plotter work within our network
system called the “NavNet.” Each product has an IP address to communicate with NavNet
compatible products within the network, using TCP/IP protocol through an Ethernet
10BASE-T network.
The main features are as follows:
• Bright 7” screen visible even under direct sunlight.
• User friendly operation with combination of discrete keys, soft keys, and cursor pad.
• Accepts the following SD chart cards: NAVIONICS GOLD or C-MAP NT+/NT MAX charts,
depending on specification. All names mentioned above are registered trademarks of their
respective companies.
• Fast chart redraw.
• Built-in NavNet interface circuit board.
• Highly accurate, WAAS-capable 12-channel FURUNO BB GPS Receiver GP-320B/330B
and Weather Station WS-200 optionally available. (Hereafer these models are collectively
referred to as FURUNO BB GPS receiver.)
• User programmable function keys.
• Video sounder picture available with connection of the optional Network Sounder.
• ARP function (when connecting with MODEL 1824C series)

ix
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
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

1.3 Turning the Unit On/Off
Press the POWER/BRILL key to turn the unit on. A beep sounds and then the equipment
shows the startup NavNet screen (about 20 seconds), the product information screen,
startup test results and chart usage disclaimer. During this period the equipment is
inoperative. The startup test checks the ROM, RAM, internal battery and backup data for
proper operation, displaying the results for each as OK or NG (No Good). If NG appears an
appropriate message appears on the screen. For any NG, try to press any key to go to the
chart disclaimer screen, then perform the diagnostic test as shown in the paragraph “8.6
Diagnostics.”
For start up with the radar display, the magnetron takes from 60 seconds to 90seconds
(depending on radar model) to warm up before the radar can be operated. The time
remaining for warming up of the magnetron is counted down at the center of the display.
You may press any key at the chart disclaimer screen to show the last-used display, or wait
several seconds to let the equipment do it for you.
To turn the unit off, press and hold down the POWER/BRILL key until the screen goes dark
(approx. 3 sec.). To protect the LCD attach the hard cover. Note that the network sounder
will be turned off approx. three minutes after turning off the power. This is due to the
system’s electrical characteristics.
Note: The first time you turn on the power (or any time the power is applied after a memory
reset), you are asked if you want to start the simulation mode, which provides simulated
operation of the equipment after the installation mode selection. Push the ENTER knob to
start the simulation mode, or press the CLEAR key to start normal operation. For further
details about the simulation mode, see the paragraph “1.10 Simulation Display.”
