Marine VHF Radiotelephone with Class D DSC, GPS Receiver, AIS Receiver, and
Simplified Loud Hailer
The FM4800 is a new 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, such as center-console boats. The unit can be mounted on its
lightweight bracket, either desktop or overhead, or it can be flush mounted. The
FM4800 shares a common appearance with other Furuno equipment, such as NavNet
TZtouch2, NavPilot 711C, and the FI70 Instrument series, offering an integrated
appearance to any helm.
With its built-in GPS receiver, the FM4800 does not require an external GPS
source to enable its DSC functionality. The unit can be used as a backup source
of GPS positioning for other onboard electronics. Its built-in AIS Receiver can
be used to overlay AIS targets with networked GPS Plotters or MFD's, such as
NavNet TZtouch, NavNet TZtouch2, or GP1871F/GP1971F combo units.
Built-In GPS, DSC and AIS
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.
Loud Hailer, Intercom, and Listen
The FM4800 can operate as a simplified Loud Hailer with intercom, featuring 8
patterns of alert sounds. Loud Hailer, Fog Horn and Warning Signal features are
all available, enhancing onboard safety and communications while navigating in
the dark or fog. When connected with the second-station handset, intercom
communications are available, allowing communications between the two devices.
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.
In this way, a person on the deck can easily communicate with the bridge, a
particularly useful feature for a variety of fishing vessels and workboats. The
Listen Back function can also be an effective tool on sport fishing vessels,
allowing the horn speaker to collect the sound from fishing rods and lines when
you get a strike
