Fully compliant with IMO resolution MSC.148(77)

The NT-2000 is designed to fully comply with the new NAVTEX standards specified in the IMO Resolution MSC. 148(77) which came into effect on jULY 1, 2005

8-inch Colour LCD Display

An 8-inch colour TFT LCD replaces recording paper. Taking full advantage of a colour display, the NT-2000 shows search and rescue (SAR) messages in red to clearly differentiate distress messages from navigational or meteorological warnings. Three colours are selectable for the screen background for ease of reading, easy on the eye operation under all ambient lighting conditions

Simultaneous Reception of 518 and 490 or 4209.5 kHz

Two independently operating receivers, one with a frequency converter, are built-in to simultaneously receiver international (518 kHz) and either of 490 kHz or 4209.5 kHz domestic transmissions. If both international and domestic broadcasts occur at the same time, the NT-2000 displays international channel messages, while storing local channel messages in memory for reviewing at a later time. A single keypress swishes the first and second channel text pages.

Large Character Size, 40 characters/line, 20 lines/ screen

NAVTEX message screen consists of 19 lines and 40 characters/line plus two status and command lines for user-interface, displaying the text with a minimum of carriage returns and line feeds. Large 5-mm high fonts, 2 types selectable, are used for enhanced readability enabling you to read text from several meters away.

Single-Keypress protection of stored messages

Sotred messages are searchable by station ID and/or by message category, and can be output from a total of three external interface connectors for printing on line for processing by shipboard or shore-based applications. Alarm outputs are also available from a devoted connector for triggering a remotely located alarm device.

Three-Frequency single whip active antenna

A 1.2 meter three frequency active antenna is included as standard for space-limited installation. Specially designed front-end filtering allows the international channel and user-selected second channel transmissions to be received on the same antenna simultaneously without cross-channel interference and without sacrificing sensitively or IMD performance
