See paragraph 7.4.5 for details.
NOTE:
Forced carriage return
When the number of characters in a line exceeds 40, an internally generated carriage return
symbol, shown above, will be automatically inserted in the 40th character position to divide the
last word, forcing the rest of the characters in the word to shift to the top of the next line. This
symbol will be replaced by an underscore ( _ )
(hex 5F )
when it is printed or output to an IBS/INS
device via the RS–422 port.

End–of–Message Indication
NNNN
The appearance of these four successive
N
characters indicates the end of the
currently displayed NAVTEX message.
NOTE: Some messages including those from Chinese stations, end with NN (2 Ns)
instead of NNNN (4 Ns), in which case, the equipment will consider that the
transmission has not ended properly, and will not, therefore, display and store such a
message, or will append it to a new message, if received within a specified period of time,
and display the two messages combined. The RS–232C port (printer port) may be set to
output such messages. See paragraph 4.9 for setting instructions.
