Features
NAVTEX (Navigational Telex) is a worldwide coastal telex broadcasting system. Coastal
NAVTEX broadcasting stations with specific ID's transmit Navigational warnings, Meteorological
warnings, Search and Rescue (SAR) information and other navigational information for
NAVTEX receiver-equipped vessels sailing in coastal waters.
The FURUNO NX-300 NAVTEX receiver receives NAVTEX message s and auto matica lly
displays them together with station ID and message category information.
The service range of a NAVTEX station is typically 200-400 nautical miles. A NAVTEX station
normally br oa dcasts ever y 4 hour s.
The NAVTEX message is relevant for all types and sizes of vessels. The NX-300 is shipped
from the factory equipped to receive 7 specific types of NAVTEX messages from all NAVTEX
stations. However unnecessa r y stations can be re jected or necessary stations can be added by
the "manual station selection" facility.
If ship's position data is fed from navigation equipment, the NX-300 automatically decides in
which NAVAREA the vessel is navigating, and selects stations. (NAVAREAs are geographical
zones defined by the International Maritime Organization.)
• Unattended operation once required data is entered.
• Received data is not saved nor displayed when the error rate exceeds the percentage you set
(max 39%).
• No paper required
• Designed for sm al l boats and fi shing vessel s
• Compact, stylish display and antenna units
• Memory of up to 28,000 characters for last 72 hours
• Navigation data can be fed through external input (connection with navigation aid required).
• Bright 95 x 60 mm LCD with adjustable contrast and brilliance
• Memory backup with a long-life lithium battery
• Low power consumption

1. PRINCIPLE OF NAVTEX SYSTEM
1.1 How NAVTEX Works
There are many types of navigational and meteorological information available on radio, such
as NAVAREA, HYDROPAC, etc. However, these systems rely heavily upon the operator's
experience and skill in tuning the radio and interpreting messages. In addition, constant
monitoring to pick up wanted information among a vast volume of messages is not practical with
a limited radio staff.
To provide all mariners with up-to-the-minute information automatically, the NAVTEX system
was de veloped.
NAVTEX is an acronym meaning Navigational Telex, and as its name shows, it is a kind of
narrow band radio teletype system for sending (by frequency shift keying) text messages
expressed in a 7-unit code. The difference is that a NAVTEX transmitter transmits nine control
characters (header code) ahead of the main message, so that the receiver can identify the
station, message type and serial number automatically.
1.2 NAVTEX System Operation
For navigation purposes, the world is divided into 16 areas (called Navareas) as shown in the
figure below. Each Navarea has multiple NAVTEX stations and each NAVTEX station has an
identification code, from "A" to "Z." The frequency assigned to NAVTEX is only one (518 kHz),
and many stations exist in the same Navarea. (Some stations use 490 kHz also.)
Figure 1-1 NAVTEX area
If the stations were to transmit without any rule, the system would collapse due to mutual
interference. To avoid this problem, the following rules apply.
• The transmission schedule is determined so that two or more stations having a common
service area may not overlap in time.
• Each station transmits with minimum required power to cover its service area (200 nautical
miles nominal).
1-1
1.3Message Format
For automatic identification of messages, each message starts with eight control characters,
called "Header codes".
The first four characters are always "ZCZC" and common to all messages. This part is used for
message synchronization. The latter four characters are designated as b1, b2, b3 and b4 to
indicate origin, category and serial number of the message.
Character b1 is the identification letter of the NAVTEX station; "A" to "Z". Character b2 indicates
the type of message, "A" to "Z", as listed below. Character b3 and b4 indicate the serial number
of the message. The serial numbers are counted up from "01" to "99", and start from "01" again.
Number "00" is specially reserved for important emergency messages, such as a search and
rescue (SAR) message.
The end of each message is indicated by "NNNN" (four successive N's).
General message format is summarized below.

5.3 When the Battery Icon Appears
A lithium battery (type: CR2354-1F2, code no.: 000-142-305) is installed on the circuit board
inside the display unit, and it preserves data when the power is turned off. The life of the battery
is about 5-10 years. Its voltage is checked when the power is turned on. When its voltage is low
the battery icon appears on the display to alert you. When this happens, contact your dealer to
request replacement of the battery.
Note: When the battery is dead, all default settings are restored.
5-2
5.4Replacement of Fuse
The 1 A fuse in the snap-in fuse holder on the power cable protects the equipment from
equipment fault and reverse polarity of the ship’s mains. If the fuse blows find out the cause
before replacing it. If the fuse blows again after replacement, contact a FURUNO agent or dealer
for advice. Use only a 1 A fuse – use of a different fuse will damage the equipment and void the
warranty.
CAUTION
Use the proper fuse.
Use of a wrong fuse can cause fire or
equipment damage.

6. INSTALLATION
6.1Installation of Display Unit
Mounting considerations
The display unit can be installed on a tabletop, on the overhead, or in a panel (optional flush
mounting kit required). Refer to the outline drawings at the end of this manual for installation
instructions. When selecting a mounting location, keep in mind the following points:
Locate the unit away from exhaust pipes and vents.
•
The unit is waterproof thus it can be installed outdoors. However, locate it of direct sunlight, (or
•
in a suitable, ventilated enclosure) to prevent heat which can build up inside the cabinet.
The mounting location should be well ventilated.
•
Mount the unit where shock and vibration are minimal.
•
Allow sufficient maintenance space at the sides and rear of the unit and leave sufficient slack
•
in cables, to facilitate maintenance and servicing.
Observe the following compass safe distances to prevent deviation of a magnetic compass;
•
Standard compass, 0.5 m, Steering compass, 0.3 m.
After you install this equipment, perform All Clear as in paragraph 4.3 on page 4-1.
•

6.2Installation of Antenna Unit
Mounting considerations
Install the antenna unit referring to the antenna installation diagram at the end of this manual.
When selecting a mounting location for the antenna unit, keep in mind the following points:
Do not shorten the antenna cable (10 m cable fitted to the antenna).
•
The length of the whip antenna for the NX-3E should be no longer than 1.2 m and no larger
•
than 5 mm in diameter to prevent antenna damage. Do not use a 2.5 m whip antenna. Use
spring washer (supplied) for whip antenna.
The NX-300 contains a very sensitive receiver. To avoid mutual interference with other radio
•
equipment, do not install this unit near an SSB/VHF/CB radiotelephone.
If the antenna cable is to be passed through a hole which is not large enough to pass the
•
connector, you may unfasten the connector with a needle nose pliers and 3/8-inch open-end
wrench. Refasten it as shown in Figure 6-2, after running the cable through the hole.
If you install the antenna unit except the NX-3E and the NX-3H, contact your dealer.

Grounding
• The ground wire (local supply) should be 1.25 sq or larger for Navtex Receiver. The ground
wire should be as short as possible.
• The signal ground and frame ground are separated, however the power line is not isolated.
Ther efo re, if conne c ti ng othe r equ ip m ent whi ch ha s sign a l gr ound co nn ect ed to f ram e gr ound ,
the earth lamp will light. Especially, for positive ground battery separate the f rame ground of
the external equipment from the earth. If not, the equipment may be damaged.
External equipment
The power supply port is commonly used for connection of external equipment such as
navigation equipment or a PC. Refer to the interconnection diagram on page S-1 for connection.
6.4 Interfacing
This equipment can receive navigation data in RS-232C format. For example, it can receive
position data from GPS navigator GP-31/GP-36 for display on its screen. If you want to connect
equipment which outputs data in a format other than RS-232C, a level converter is required for
interface. Consult FURUNO dealer for details.
