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-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.
Essential navigational data is clearly
displayed at the bottom of display when
connected with a positioning equipment.
Three font sizes are available for convenience
of the operation.
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.
