The GMDSS (Global Maritime Distress and Safety System) was developed to improve maritime radio communications, particularly those involving distress and safety, by using the most up-to-date communications technology. The A21815 can be used in Sea Area 2, within the coverage of at least one MF coast station in which continuous DSC alerting is available, as defined by a Contracting Government. Normally within 150 n.m.
The A2 GMDSS equipment includes the following:FM8800S - DSC-VHF/FM Marine Radiotelephone
FURUNO FM-8800S is a high quality, all-in-one marine VHF radiotelephone designed to comply with the GMDSS carriage requirements for safety and general communications. All the necessary functions such as a 25 W VHF radiotelephone, a Class A DSC modem and a CH 70 Watch Receiver are incorporated into the compact transceiver unit.
The FM-8800S offers simplex/semi-duplex voice communications with high sound quality thanks to its speaker designed to lower the strain. Operators are allowed to conduct communication clearly at any situation. For easy readout of a selected channel, the silver-bright LCD is placed on the front panel indicates the channel numbers with large and easy-to-read characters. Selected channel is easily made with the dedicated rotary control or numeric keys. Other standard features are instant access to CH 16, telephone call via a PSTN, Dual Watch and Multiple Watch functions, which allow watch on CH 16 and other selected channels.
Full Class A DSC functions are provided for distress alert transmission and reception, as well as the general DSC communications including Individual Telephone, All Ships, Group and Area Call. The FM-8800S maintains a continual watch on CH 70 even while you are using another VHF channel. Upon receiving an incoming DSC message, the FM-8800S gives aural and visual alarms.
ATIS (Automatic Transmitter Identification System) is standard fitted for use in European inland waterways. It automatically transmits the ID number when a communication is over or every 5 min while in communication. The ATIS mode and DSC mode are selectable through the menu.
FS1570 - MF/HF Radiotelephone/DSC Watch Receiver (150W)
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.
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.
