LED indicator functions

Green LED indicator
This indicates that the AIS transceiver is configured, powered up, and operating normally.
Red LED indicator
Indicates that the AIS transceiver has detected a system error. The likely causes of this are detailed in the troubleshooting guide in the 8900 Series user manual. Alarms displayed in the Diagnostics tab of the em-trak configuration tools will also assist with troubleshooting.
Amber LED indicator
This indicates that 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 LED 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.

Blue LED indicator
Indicates that silent mode is enabled. Silent mode is a feature of the 8900 Series that ceases the transmissions from your own vessel, whilst the reception of other vessel position reports continues. You can activate this using the configuration tools or by activating the toggle switch as detailed in the B900 Series user manual.

US customers only

In the USA it is illegal for end-user to configure their own AIS with their vessel data. To do so is a violation of the rules of the United States Coast Guard (USCG). This must be done by a competent installer, such as an em-trak, an em-trak dealer, or competent marine electronics professional. If your transceiver has not been pre-configured for you please refer to your dealer or contact support@em-trak.com for advice on how to have the transceiver configured legally. If purchasing direct from em-trak online we can configure it for you and dispatch it pre-configured at no extra cost, if you are purchasing from one of our dealers, then they will do it for you.
