AIS messages can be viewed, created and transmitted from the
‘Messages
’
menu.
The available options are:
Compose - takes you to the message composition screen
Inbox - takes you to the received message list view
Sent - shows a list of recently sent messages.
To compose a new message, select the type of message from the drop down
menu and the destination. This can be by directly entering the MMSI, or by
selecting from a list of visible targets.
The message text is entered using the on screen keyboard. Messages are
limited to 80 characters in length.
Class B AIS transceivers are permitted to receive broadcast
SRMs and broadcast text messages, however this function is not
mandatory. Some Class B AIS transceivers are not able to
receive addressed SRM or text messages. There is therefore no
guarantee that text messages or SRMs sent by this device to a
Class B AIS transceiver will be received.
4.6.9 Long range messages
If the AIS transceiver is connected to a long range communication system via
the long range communications port then long range interrogations may be
received. These are requests for information from a distant base station
beyond normal AIS operation range.
The AIS transceiver can be configured to automatically respond to Long
Range (LR) interrogations, or you can opt to respond to any interrogation
manually. Automatic response is the default setting, but this can be changed
on the
‘Home’ > ‘System settings’ > ‘Advanced’ > ‘Radio and Long range
settings’
menu.
When a Long range interrogation is received you will be alerted by an on-
screen pop-up message.
In automatic response mode simply review and acknowledge the notification
screen using
‘Acknowledge’
. In manual response mode you should review the
request and select either the
‘Respond’
or
‘Decline’
option as appropriate.
