not displayed on receipt, however the message icon will be displayed at the
top of the screen.
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. 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 to a Class B AIS
transceiver will be received.
4.6.9 Chart
The AIS transceiver contains an application which will display AIS targets
received, along with its own vessel position on a chart style plot.
The chart can be scrolled up, down, left, and right using the
‘Function’ keys.
Zooming in and out is via the ‘Scroll’ wheel.
Targets can be selected by moving the cross hairs over a target and pressing
the
‘Select’ key.
The ‘Options’ menu is also available for more advanced features.
Within the ‘Options’ menu, the chart can be oriented to either North, Heading,
or Course Up. The chart can be set so that the own vessel position is always
in the centre of the screen.
The chart can be de-cluttered by hiding filtered targets, or vessel names from
the display.
