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
Enhances the navigation efficiency and safety by watching NAVTEX
messages broadcasted on both international and local channels
- 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.
- 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-700A consists of a receiver, display with printer and antenna units. The N
