8.3.7 Alert messages
The transceiver can be configured to transmit text messages for three different alert conditions.
An addressed or broadcast text message can be transmitted when the transceiver detects a Built In
Integrity Test (BIIT) failure.
An addressed text message can be transmitted to an approaching vessel if the vessel comes within a
configurable distance of the transceivers location. This function is only available with Type 3 variants
and with full time receiver operation.
An addressed or broadcast text message can be transmitted when the transceiver determines that it
is off position (see section
8.3.1). This message is in addition to use of the alternate schedule for off
position reporting (if the alternate schedule is enabled) and does not replace that function.
The layout of the alert messages configuration tab is provided in Figure 24.

BIIT failure actions
This section allows configuration of the text message to be transmitted on detection of a Built In Integrity Test
failure (BIIT failure). Such a failure may indicate a problem with the transceiver and it may be prudent to warn
vessels not to rely on the information provided by the transceiver in this situation. Note that the health of the
transceiver is always transmitted as part of the standard Aids to Navigation position report (message #21),
however the status contained in that message may not be shown on all display systems.
The available actions on BIIT failure are:
No action - no message is transmitted on detection of a BIIT failure.
Transmit message #14. A broadcast text message is transmitted on detection of a BIIT failure. The
text content of the message must be defined in the ‘Message text’ box.
Transmit message #12. An addressed text message is transmitted on detection of a BIIT failure. The
destination for the addressed message is configured on the ‘Real AtoN’ tab (see section
8.3.1).
In addition to configuration of the BIIT failure action a schedule for the associated message must be configured
in the ‘Message schedule’ tab.
Message #14 Index 1 must be configured if the message #14 action is selected.
Message #12 Index 1 must be configured if the message #12 action is selected.
Vessel proximity alert
This section allows configuration of the text message to be transmitted on detection of vessel breaching a
defined radius (or guard ring) around the transceiver. This message can be used to warn approaching vessels
of potential collision with the AtoN. The addressed message is automatically sent to all vessels that breach the
guard ring radius.
