4 Configuring your AIS transceiver Until correctly configured, your AIS class B transceiver will only receive AIS messages and will not transmit AIS messages. Switching on your AIS transceiver for the first time A few seconds after applying power to the AIS transceiver, the indicators on the unit will illuminate in a pattern dependent on the configuration state of the unit. The function of the four indicators are: Indicator Green Amber Red Blue Function Unit is powered up and operating normally Unit is in a 'transmit timeout' period Unit has experienced an error Silent mode is activated If the AIS transceiver has been pre-configured, the amber indicator will illuminate until a transmission has been sent by the unit. This may take several minutes, as the transceiver must acquire a GPS position fix prior to transmitting its first message. If the transceiver has not been pre-configured, the amber and red indicators will be illuminated until the configuration process has been completed.
