Frequently Asked Questions
Does the FM4800 require an external GPS antenna for DSC functionality?
No, the FM4800 includes a built-in 72-channel GPS receiver that provides positioning data for DSC operations without requiring an external GPS source. It can also serve as a backup GPS for other onboard electronics.
Can I initiate DSC calls directly from my chart plotter?
Yes, when connected to NavNet TZtouch2 MFDs via NMEA2000, you can initiate DSC calls by simply tapping on AIS/DSC targets and selecting "DSC Call" directly from the multifunction display interface.
What is the Listen Back function and how is it used?
Listen Back allows the horn speaker to collect external sounds and transmit them through the built-in speaker. This enables deck-to-bridge communication and can be used for fishing applications to monitor sounds from rods and lines when fish strike.
Is the FM4800 compatible with legacy NMEA 0183 equipment?
Yes, the FM4800 outputs NMEA 0183 position, AIS, and DSC data to legacy equipment while also providing NMEA2000 connectivity for modern marine electronics integration.
What loudhailer features are included with the FM4800?
The FM4800 includes a 30-watt loudhailer with 8 automatic fog/warning signal patterns, fog horn capability, PA function, intercom communication, and the unique Listen Back feature for two-way external communication.
