• The unit may not have a valid MMSI. Check that the AIS
transceiver is correctly configured with a valid MMSI.
• 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 the connection
to the GPS antenna and that the GPS antenna is not
damaged.

the power supply is within the range 9.6V to 31.2V.

your dealer for advice.
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.
