NOTE: When a type–D message (SAR, piracy and armed robbery information) is
received on either the first or second receiver, automatic scrolling will be disabled until
the user acknowledges the
message with

or with a software command from an
IBS/INS terminal via the rear–panel
RS–422 connector. See paragraph 7.4 for details.
④Receiver Operating Status Indication
The current status of receiver operation is indicated here.
・ABORTED: The receiver has failed to lock onto the current transmission,
due, for example, to weak signal level or noise interference.
No message will be displayed or stored.
NOTE: Signal propagation conditions change greatly with time.
You might not be able to receive a signal in the daytime that can
be received at night; this is normal and should not be considered
as a sign of receiver malfunction.
・ACQUIRING: The receiver is currently in the process of locking onto the
start of the current message transmission.
・LOCKED: The receiver has locked onto current NAVTEX transmission,
allowing a message to be received. As soon as the equipmet
starts receiving the message, this indication will be replaced
by RCVNG MSG.
・RCVNG MSG: The receiver is properly receiving a message after locking
onto current transmission. This blinking indication will stay
until the end–of–message code NNNN (⑩) is received.
NOTE: Whether to display or output the message to external
devices depends on the character error rate
(CER, ⑫) and on
the selection/rejection settings to be made via the procedure in
paragraph 4.8.
・STANDBY: The receiver is idling, waiting for a NAVTEX message
transmission to begin. Most stations transmit messages every
4 hours.
⑤Operating Status Line
The current status of receiver operation, text scroll keys, etc. are indicated here.
Examples:
・1ST RCVR MSG: Message received on the first receiver is currently displayed.
・2ND RCVR MSG: Message received on the second receiver (490 or 4209.5 kHz)
is currently displayed.
・ : Message can be scrolled line by line by pressing /.

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.
⑩End–of–Message Indication NNNN
The appearance of these four successive Ncharacters 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.

⑪Indication of Message Storage Status
This indication shows whether or not the displayed NAVTEX message has been
stored in the internal non–volatile memory.
･*1STORED: The message has been stored.
When message reception has been completed with a character error rate (CER,⑫)
of 33% or less, the received NAVTEX message together with its ID will be displayed
and stored in memory, making it possible to recall it onto the screen at a later time.
If the same message is received with a lower CER on the next transmission, the
previously stored message will be replaced with the new one. However, if the first
message was received with a CER of 4% or less, message replacement will not take
place on subsequent reception with a lower CER.
When the CER exceeds 33%, the message and its ID will not be displayed and will
not be stored in memory, allowing a retransmission of the same message to be
displayed and stored.
*1:
If the message selection/rejection settings are made so that a particular message
type is rejected from storage, this indication will not be displayed regardless of a
CER
being smaller than 33%. See paragraph 4.9 for the related setting instructions.
⑫Character Error Rate (CER) Indication
CER is the percentage ratio of the total number of corrupt characters represented
by asterisks (*) to the total number of characters received in a message, including
control codes (sync. signal, carriage returns, line feeds, letter/numeral shift, etc.).
If a message is received with a CER equal to or greater than 33%, the message will
not be displayed and stored in memory, allowing the same message to be received
again on its next transmission. No CER reading will be available on the current
transmission.
See paragraph
⑪for more information on CER.
⑬Message Prompt Line
This line indicates the receiver’s response for the user’s keypress or displays
prompts related to reception of new or alarm NAVTEX messages on the first or
second receiver, or related to message storage, like the examples below.
