Furuno Fixed Mount Marine VHF Radiotelephone with Class D DSC - FM4800

The Furuno FM4800 is a marine VHF radiotelephone with built-in Class D DSC, GPS Receiver, AIS Receiver, and Simplified Loud Hailer with intercom. Its compact housing enables it to be installed in a variety of craft, even vessels where space is limited. The unit can be mounted on its lightweight bracket, or it can be flush mounted.

With its built-in GPS receiver, the FM4800 does not require an external GPS source to enable its DSC functionality. Its built-in AIS Receiver can be used to overlay AIS targets with networked GPS Plotters or MFD's.

An existing GPS source can be connected to the FM4800, and it can share its own GPS, DSC and AIS information via NMEA0183 or NMEA2000. When connected via NMEA2000 to any NavNet TZtouch2 MFD, DSC calling can be initiated directly from the TZtouch2 MFD by simply tapping on the AIS/DSC target and selecting [DSC Call]. Additionally, when MOB (Man Overboard) is activated on a TZtouch2 MFD, the FM4800 enters a special mode where you can initiate a distress call by simply pushing the rotary knob.

The FM4800 can operate as a simplified Loud Hailer with intercom, featuring 8 patterns of alert sounds. When connected with the second-station handset, intercom communications are available. Additionally, the horn speaker can be used to collect external sounds and transmit them through the built-in speaker with a function called Listen Back.
