There may be a problem with the VHF antenna sys-
tem. This can be confirmed using proAIS2. If the
'High VSWR' alarm is active please check for the fol-
lowing:
● Faulty VHF antenna/cable/connectors
● Poor connection at the VHF antenna/cable/
connectors
● Suitability of the VHF antenna (for AIS only we
recommend antennas tuned to 162MHz / for
splitter variants we recommend antennas tuned
to 159MHz)
● VHF antenna location (ensure that is isn't
mounted near other transmitting antennas or
sources of interference, metal structures, or
other obstructions)
The red 'error'
indicator is
illuminated
● Check that the unit is programed with a valid
MMSI number. This can be confirmed using the
Configuration tab in proAIS2
● Check that the GNSS antenna has a stable
position fix. This can be confirmed using the
GNSS Status tab in proAIS2
● Check that the power supply is within 12 - 24V.
This can be confirmed using the Diagnostics tab
of proAIS2
