Turning Off AIS Broadcast Warning Messages
The reception of AIS Broadcast Warning Messages is turned on by default. This includes messages intended for the protection of marine mammals.
AIS broadcast messages must be turned on for you to receive them. If this feature is turned off, you will not receive these messages, including those intended for the protection of marine mammals. Failure to have these messages on could lead to injury or property damage.
Select
> Other Vessels > AIS Broadcast Safety Messages.
> Other Vessels > AIS Broadcast Safety Messages.
You will no longer receive AIS broadcast messages. You will continue to receive AIS addressed messages, because those message designations cannot be disabled.
