Amber indicator
The AIS transceiver is not transmitting. This can be for a number of
reasons:
● The AIS radio channels are exceptionally busy so there are
currently no available slots for transmission.
● The unit has been in silent mode and after deactivating
silent mode this amber indicator will illuminate until the first
AIS message has been sent
● The AIS transceiver has been commanded by the local
authority (via an AIS base station) to cease transmissions.
