Cause/Source
Reaction: The transponder unit stops transmission. If Alarm ID 01 and ID 02
are simultaneously displayed, then a major antenna problem has arisen.
Remedy:
VHF Antenna,
Check if the antenna is AIS compatible (156-162 MHz) and if the antenna
cabling
cabling has a short circuit or is missing any contacts at the connectors.
If the ID 01 is displayed as a stand alone message, then the unit requires
replacing.
Reaction: The transponder unit continues transmission.
VHF antenna,
Remedy:
Check the antenna and the antenna cabling (RG214 / 50 Ohm cable
installation
required).
Reaction: The transponder unit stops transmission on the affected channel,
Internal error Remedy;
If this alarm reoccurs regularly, then the transponder unit requires replacing.
Reaction: The transponder unit stops transmission.
Internal error
Remedy;
The transponder unit requires replacing.
Reaction: The transponder unit continues operation using the position data of
the internal GPS. If there is no valid position data available from the internal
GPS, error 026 is additionally displayed.
