• The VHF antenna may be faulty. Please check
the connection to the VHF antenna and that the
VHF antenna is not damaged. The red indicator
may illuminate briefly if the power supply is
interrupted or the VHF antenna characteristics are
briefly affected.
• The GPS antenna may be faulty. Please check

GPS antenna is not damaged.

My MMSI is being
received by other vessels
but my vessel name is
not shown on their chart
plotter or PC
• Some older AIS devices and chart plotters do not
process the specific class B AIS message which
provides the vessel name (message 24). This is
not a fault of your AIS transceiver. Software
upgrades are available for many older chart
plotters which will correct this issue. The other
vessel should update its AIS unit and/or chart
plotting software to receive AIS message 24.
