The FS1570 is a MF/HF radiotelephone that is fully capable of GMDSS operations. In addition to standard radio operation, it can operate as DSC (Digital Selective Call) on general communications and as a DSC Watch Receiver on all distress and safety frequencies in MF and HF bands. A telex modem (NBDP) accompanies the transceiver unit for general message transfer and distress message/maritime safety information handling, satisfying the carriage requirements for GMDSS A3-A4 sea areas.

The FS1570 maintains a continuous watch on a distress call, even while you are exchanging normal voice messages. The DSC channels can be individually set or all selected channels can be automatically scanned. When a DSC message is received, the radiotelephone gives audible and visual alarms. It works on all authorized transmit frequencies between 1.6 and 27.5 MHz. Receiver frequencies are selectable between 100kHz and 30Mhz in 10Hz steps. The transmit and receive frequencies can be selected separately or in pair. The digital frequency synthesizer provides high frequency stability for DSC and NBDP as well as telephony operation.

IB583 Terminal

The IB583 is a 10.4" color LCD display for use with RC1800 series GMDSS consoles. The IB583 displays messages at 72 characters/line with 25 lines/screen. File management, text editor and utility programs ensure easy operation. The terminal also comes with a disk drive.

INMARSAT-C MES FELCOM 15

The Inmarsat-C system provides a quality two-way telex and data link between ships and other parties at sea or on land. The Felcom 15 provides all functions and services of the Inmarsat-C system: EGC (safety NET/FleetNET), distress message handling, two-way digital store-and-forward messaging including polling, data reporting, E-mail, etc.

Distress alerts are initiated by the remote distress alert unit. The distress message including own ship's position is easily edited. The distress alert button is incorporated in the display for emergencies.
