Introduction
Introduction 1
SAILOR 6390 Navtex Receiver
The SAILOR 6390 Navtex Receiver receives Navtex messages on the 
international Navtex frequencies 490 kHz, 518 kHz and 4,209.5 kHz. It can 
hold 2000 messages per frequency. Messages are not affected by a power 
cycle. If not tagged to avoid deletion, messages are cleared from the 
message log after 661 hours. You can customise which stations to receive 
messages from and which message types you want to receive. The unit has 
an alarm relay which is only activated if a message of category D is received 
(i.e. SAR, Mayday relay, Pirate attack etc.). The SAILOR 6390 Navtex 
Receiver is always on when powered. With its LAN interface the 
transponder and the display can be separated, giving access to the Navtex 
information available where it is needed.
The SAILOR 6390 Navtex Receiver is delivered as a black box receiver 
which can either be connected to the SAILOR 6004 Control Panel, a 7" 
touch screen, or used as a standalone unit for integration with an INS, 
supporting NMEA0183. A printer can be connected to the receiver.
The SAILOR 6390 Navtex Receiver is approved according to GMDSS (EU 
Marine Equipment Directive).

4 Use scenarios
Use scenarios
The SAILOR 6390 Navtex Receiver can be used in the following contexts:
•Use with the SAILOR 6004 Control panel
•Use as a stand-alone unit with an INS
An optional printer can be connected in both use scenarios.
Use with the SAILOR 6004 Control panel
The SAILOR 6004 Control panel is the user interface for the SAILOR 6390 
Navtex Receiver. The user interface is in English. All settings that are 
relevant for the user are accessed through the touch panel. Alarms and 
notifications are shown in the display and via NMEA. The SAILOR 6004 
Control panel has a buzzer for alarm tones and the display supports night 
mode. The SAILOR 6390 Navtex Receiver has a Navtex application which is 
loaded into the SAILOR 6004 Control Panel during installation.
Use as a stand-alone unit with an INS
The SAILOR 6390 Navtex Receiver also works as a stand-alone unit, 
integrated in the vessel’s INS. It supports the Navtex specific NMEA 
sentences according to the standard IEC 61097–6 and IEC 61162-1. For 
further details see the documentation of the INS.

Filtering stations
The SAILOR 6390 Navtex Receiver can automatically filter messages from 
coast stations within a certain range of NM of own position (default). You 
can also filter coast stations manually.
For a list of stations see the Admiralty List of Radio Signals and ITU List of 
Coast stations and Special Service Stations (List IV) (http://www.itu.int).
To set up filters for stations do as follows:
1. Tap the menu icon and then Filters.
2. Tap Printer, Display or INS to select for which output you want to set 
up a filter.
3. For automatic filtering select Automatic Mode.
Tap Range, select the wanted radius in Nautical Miles and tap Apply. 
The coast stations within this range are displayed.1
4. For manual selection, deselect Automatic Mode and tap the 
frequency you want to set up a filter for, e.g. 490 kHz Stations.
Swipe the field Select stations, select the stations you want to receive 
on this frequency and tap Apply. The selected stations are displayed 
directly below the frequency.
1. For Automatic Mode the SAILOR 6390 Navtex Receiver must have a valid 
GPS input. Without a valid GPS input you can only filter manually.

Printer attached to the SAILOR 6004 Control Panel 
A printer can be connected to one of the USB connectors of the SAILOR 
6004 Control Panel. Every time a Navtex message is received and applies to 
the filtering set up for Printer, the message is output on the printer.
The SAILOR 6390 Navtex Receiver applies header and footer information 
to the printout, stating frequency, date and time of reception and serial 
number of the SAILOR 6390 Navtex Receiver.
If the printed message line is longer than allowed on the printer, the printer 
inserts the sign to indicate a forced line division and breaks the line.
Selecting print lists
To print a selected list do as follows:
1. From the list of messages, tap the menu icon and Print.
2. Tap the list you want to print.
Operation with INS equipment
Messages filtered out using the INS filter settings are sent to the INS 
equipment via NMEA. See the user documentation for the INS for further 
information how Navtex messages are displayed and printed.
