FOREWORD
A Word to NX-300 Owners
Congratulations on your choice of the FURUNO NX-300 NAVTEX Receiver. We are confident
that you will enjoy many years of operation with this fine piece of equipment.
For over 50 years FURUNO Electric Company has enjoyed an enviable reputation for quality and
reliability throughout the world. Our extensive global network of agents and dealers furthers this
dedication to excellence.
The NX-300 is just one of the many FURUNO developments in the field of marine radio
communication. The NX-300 provides cost-effective price, high sensitivity and simple operation
in one compact and light-weight unit. In addition to its fundamental function of receiving NAVTEX
broadcasts, this unit can also function as nav data display when connected to navigation
equipment.
This unit is designed and constructed to ensure the user many years of trouble-free operation. To
obtain full performance from the equipment, however, you should carefully read and follow the
recommended procedures for installation, operation and maintenance. No machine can perform
its intended functions unless it is installed and maintained properly.
Thank you for considering and purchasing FURUNO equipment.
v
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
1.3 Message 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.
