Typical NAVTEX Message Screen

1. Typical NAVTEX Message Screen

1.1. Introduction

The illustration below represents a typical NAVTEX message screen, showing a new

message received on the first (518 kHz) receiver. A similar screen will show up when

the equipment is switched to receive a second receiver (490 kHz or 4209.5 kHz) message.

A brief description of on–screen indications is given below and in the following pages.

Figure 1-1 Typical NAVTEX Message Screen (First Receiver Page)

①Indication of Receiver in Use to Display Current Messages

･1ST RCVR: First receiver, 518 kHz

･2ND RCVR1: Second receiver, 490 kHz or 2ND RCVR2:4209.5 kHz

The two receivers can be switched by pressing or by means of a software

command from an IBS/INS terminal via the rear panel RS–422 connector (INS

port). See paragraph 7.4 for details.

②Message No. and Total No. of Messages Stored

The message number of the currently displayed message along with the total

number of stored messages is indicated in the following format:

Examples:

・12/12: Message #12 (newest message) of 12 messages stored

・1/12: Message #1 (oldest message ) of 12 messages stored

1.1. Introduction (

continued – 2 /5

)

③Message Scrolling Keys

The keys that can be used to manually scroll messages across the current screen

are indicated.

・ : Line–by–line scrolling by pressing /

・: Message–by–message scrolling by pressing



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 /.

・STANDBY: Receiver is idling, waiting for a NAVTEX message

transmission. See ④above for details.
