SAM Navtex 2902

SAM DEBEG NAVTEX 2902 - 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 Color LCD Display

An 8-inch color TFT LCD replaces recording paper. Taking full advantage of a color display, the SAM DEBEG NAVTEX 2902 shows search and rescue (SAR) messages in red to clearly differentiate distress messages from navigational or meteorological warnings. Three colors 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 receive international (518kHz) 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 switches the first and second channel text pages.

Large Character Size, 40 Characters/Line, 20 Lines/Screen

NAVTEX message screen consists of 18 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 

Received messages are stored in non-volatile memory, and can be

recalled onto the screen line by line or message by message using

devoted scroll keys. Messages will be automatically erased from

memory after the specified time period or after the full memory

capacity is reached, but up to 50 important messages can be easily

protected from automatic erasure with a devoted key.

Message Search Function

Stored 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 or 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 sensitivity

or IMD performance
