Furuno NX-700-B User Manual

NAVTEX system operation

The world is divided into 16 areas (called Navareas) as shown at right.
Each Navarea has multiple NAVTEX stations and each NAVTEX station has
an identification code, from “A” to “Z.”
The service range of a NAVTEX station is typically 200-400 nautical miles
depending on the terrain and station transmit power. A NAVTEX station
normally broadcasts every four hours.
There are two channels including international channel, 518 kHz, and local
channels, 490 and 4209.5 kHz. International channels broadcast messages
in English. On local channels, 490 kHz, is available in the UK, France, etc.,
using their own languages. 4209.5 kHz is allocated for NAVTEX broadcasts
in tropical areas - not widely used at the moment.

Dual-channel NAVTEX Receiver

FURUNO NX-700 is a dual-channel NAVTEX receiver for SOLAS
ships complying with the new NAVTEX performance standard
MSC.148(77) which is implemented on and after 1 July 2005.

The NX-700 can receives two channels simultaneously. One is set
for 518 kHz to receive international NAVTEX messages and
another is selectable from 490 or 4209.5 kHz for domestic or local
NAVTEX messages. These messages include a variety of safety
information such as Navigational Warnings, Meteorological
Warnings, Search and Rescue (SAR) information and other
information for ships sailing within the reach of each service
station’s coverage. The broadcast station can be selected
automatically according to own ship position when the NX-700 is
connected with a GPS navigator.

messages broadcasted on both international and local channels

Every incoming message is stored in non-volatile memory and is
displayed on the clear 5" silver bright LCD. Three different font
sizes are available and one of them can be selected on menu.

The NX-700-A consists of a receiver, display with printer and
antenna units. The NX-700-B has a low profile, stylish display
without a printer, receiver and antenna units. The compact
umbrella type antenna requires no grounding because it is H-field
antenna. In addition, the antenna incorporates a high-performance
preamp within the compact body, which gives reliable and
uninterrupted reception without an extra whip antenna.

Message icons

All received messages with a selected
channel information are sorted by order of
time in the message inbox. Operators can
easily know the status of each message
from the message ID and icons. When
receiving SAR information, NX-700 notifies
of the incoming messages by audible alarm.
For quick viewing, operators can pick up
messages they are interested in and display
them by using the sort function.

Essential navigational data is clearly
displayed at the bottom of display when
