It integrates a VHF transceiver, a GPS receiver, an AIS receiver, a Class D Digital Selective Calling (DSC) function, and a deck loud hailer with intercom capability. This compact design allows flexible installation in vessels where helm space is limited.\n\u003c\/p\u003e\n\n\u003ch3\u003eIntegrated features and performance\u003c\/h3\u003e\n\u003cp\u003e\n    With a maximum output power of 25W (reducible to 1W), the FM4850 ensures reliable VHF communication. Its integrated AIS receiver operates on frequencies 161.975 MHz (AIS1) and 162.025 MHz (AIS2), enhancing safety and situational awareness at sea by providing AIS target data. The integrated 72-channel GPS receiver (frequency 1575.42 MHz) supplies position data for the DSC function and can serve as a secondary GPS source, though an optional external GPS antenna (GPA-017\/017S) is required for signal reception. The deck loud hailer delivers a maximum power of 30W (at 4 ohms), including 8 automatic fog\/horn signals and a rear listening function. Frequency stability is maintained within ± 1.5 kHz.\n\u003c\/p\u003e\n\n\u003ch3\u003eConnectivity and robustness\u003c\/h3\u003e\n\u003cp\u003e\n    The system supports simplex and semi-duplex communication with a 50-ohm antenna impedance. The 192 x 128 monochrome display is integrated into the HS-4800 handset. For integration with onboard electronic systems, the FM4850 is equipped with NMEA0183 (1 input, 1 output) and NMEA2000 (1 port) interfaces, enabling sharing of GPS, AIS, and DSC data. Power is supplied by a 12.0V DC source (-10%, +30%) with a maximum consumption of 5.0 Amperes. The radiotelephone operates within an ambient temperature range of -15° C to +55° C. The transceiver, HS-4800 handset, and SP-4800 loud hailer are fully waterproof, compliant with IP67 standards, ensuring resistance to marine environments. The system supports up to three HS-4800 handsets and SP-4800 loud hailers for multi-station capability and intercom function. It also includes an ATIS mode for inland waterways and 10 dedicated weather channels (for North America).\n\u003c\/p\u003e","brand":"Furuno","offers":[{"title":"Default Title","offer_id":56089357812052,"sku":"IMD036560AB","price":920.08,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/furuno-fm4850-vhf-radiotelephone-marine-version-black-box-loutil-ultime-5-en-1-radio-vhf-gps-recep_i-1.jpg?v=1781256641","url":"https:\/\/skysat.fr\/en-gb\/products\/furuno-fm4850-marine-vhf-radiotelephone-black-box-gps-ais","provider":"Skysat","version":"1.0","type":"link"}
