Introduction
What Is NAVTEX?
NAVTEX is a worldwide system for the broadcast and automatic reception of maritime safety
information (MSI) in English by means of narrow-band direct-printing telegraphy. NAVTEX
provides shipping with navigational and meteorological warnings and urgent information.
NAVTEX is a component of the IMO/IHO worldwide Navigational Warning Service (WWNWS)
as defined by IMO Assembly resolution A.706(17). It is included within the Global Maritime
Distress and Safety System (GMDSS). Since 1 August 1993, NAVTEX receiving capability has
become mandatory equipment for certain vessels under the provisions of the International
Convention for the Safety of Life at Sea (SOLAS).
NAVTEX broadcast information is available to all seafarers, free of charge.
How Does NAVTEX Work?
NAVTEX transmissions are sent from stations situated worldwide. The power of each
transmission is regulated so as to avoid the possibility of interference between transmitters.
Each station is allocated a 10-minute time slot every 4 hours so that many stations can share
the same frequency. Stations typically have a transmission range of 250 –300 Nm.

NAV6 Series NAVTEX System User Guide

NAV6 Features
The NAV6 adds a new dimension in NAVTEX functionality. The NAV6 offers simultaneous
reception on both the 518kHz international channel and the 490kHz local information channel.
Unlike other NAVTEX receivers that discard unselected messages, the large flash memory in
the NAV6 means it has the capacity to store all of the messages from transmitting stations
within its range. This allows you to recall, display and review any message at any time even if
it was not selected at the time of the transmission. A unique message processing (iNEC)
feature benefits you by decreasing errors in received messages in noisy or weak signal areas.
The NAV6plus includes all the features of the NAV6 standard including dual frequency and
when connected to an NMEA data source, it offers a range of standard and custom instrument
repeater functions. The NAV6plus includes a database of all NAVTEX stations around the
world and when connected to a GPS can be set to automatically display messages from all
stations within range or just the closest station helping to provide a much clearer picture of
the conditions in your area. Outputs are also included for connection to a serial printer or
computer.
The NAV6 eNAVTEX V3 Receiver module comes as standard with the NAV6 and NAV6plus.
The eNAVTEX V3 receiver includes a barometric display showing current air pressure, a
historical pressure plot for up to the last seven days and Beaufort forecast and a USB interface
for connection to a PC running the NAV6 eNAVTEX App. It has a large 4MB message store for
saving messages when the unit is not connected to a display device. The USB interface can
also be used for updates to the receiver and to a connected display unit.
The NAV6plus and NAV6repeater include additional instrument repeater functions. All the
information you really need at your navigation position on one large, easy to use display. With
navigation space becoming more and more restricted in modern boats, the NAV6plus
concentrates all the data you need, where you need it. It takes critical NMEA data from your
GPS or instrument systems and displays it in a highly innovative manner. An electronic log
book is updated at regular intervals and can be sent to a serial printer. These powerful
instrument and GPS repeater functions are included as standard in the NAV6plus.
The NAV6repeater can also be purchased separately without a NAVTEX receiver for use as a
stand-alone NMEA repeater. When added to an existing system, NMEA data and NAVTEX
data can also be repeated at another position such as the helm or fly bridge.
NAV6 Display Unit
The Display Unit uses a high resolution backlit LCD to display NAVTEX messages in a choice of
text sizes.
The display unit contains a large non-volatile memory to store NAVTEX messages, NAVTEX
station database, all of the user settings, filter options, LCD contrast and backlight levels. All
messages and settings are retained during power down.
Several messages can be displayed at once (depending upon the length of the message) and
messages can be scrolled with a single key-press.
Messages can be filtered using a number of user selectable settings.
The NAV6plus and NAV6repeater can be connected to a printer or computer to print
NAVTEX messages and Navigation logs.

Audible and visible alarms can be set up to indicate reception of SAR and/or New Messages.
A sleep mode allows long standby periods with minimum power consumption, such as when
the vessel is left in a marina with main batteries being trickle charged from the shore.
eNAVTEX Receiver Unit
The Receiver Unit contains dual receivers that can receive on both 490kHz and 518kHz
simultaneously. Up to two displays and a PC may be connected to an eNAVTEX receiver for
simultaneous operation.

The Keypad and Display
The central keys are a ‘navigation pad’ ( UP DOWN LEFT RIGHT ).
In Settings screens the LEFT key will go back to a previous level.
Softkeys 1 to 4 are situated on either side of the navigation pad. The current function is shown
on the Softkey menu area at the bottom of the LCD.
On the NAV6plus the View Indicator shows the number of top level View Screens enabled and
highlights the one currently selected. On the top level views the LEFT and RIGHT navigation
pad keys will move between View Screens. The View Screens are enabled or disabled on the
General Settings Page.
The Softkey 1 is normally the Home key and will take you back to the top level view screens
from wherever you are in the menus. Pressing the Home key twice or holding it down for
more than 2 seconds will go back to the first View Screen, which is normally the NAVTEX view
unless the display is just being used as an instrument repeater.
In the top level View Screens the Settings (Sofkey 4) will select the Settings Menu where you
can configure the NAV6.
On settings that require a change, Softkeys 2and 3, and will change the value, Softkey
3 will generally increase a value, and Softkey 2will decrease it.

490 kHz reception available
518 kHz reception available
Receiving message now
Signal Carrier, but no message
Receiver Communication fault

NEW message received
UTC Time
Viewing and Scrolling through NAVTEX messages
To view NAVTEX messages you must first select the NAVTEX View Screen. Press and hold the
Home key until the NAVTEX View Screen is displayed.
Note: This assumes the NAVTEX View has not been reordered and is still the first View as from
the factory.
You can now use the UP, DOWN, keys to scroll through the displayed messages. If you press
and hold the keys the scroll speed will increase so you can scan through the messages more
quickly.
The messages currently displayed may be a sub-set of all the messages stored in memory.
Whether you can see a particular message or not depends upon the current station selection,
message filter and age limit settings (see following sections for details).
Message Storage
All received NAVTEX messages are stored in memory regardless of whether you have them
selected for viewing or not. The NAV6 has lots of memory so you will easily have enough
storage for all messages received.
The messages displayed are selected from the NAV6 memory by applying filters to show
messages from transmitting stations and types of messages required. This enables you to
change your mind later about your message display options. This means you will still be able
to view messages that were received previously, but were not selected for display at the time,
by changing the current station and message filters.

NAV6 Series NAVTEX System User Guide
11
Once the message store has filled up new messages will start to overwrite the oldest messages
in the store. Even in areas with lots of stations and high levels of NAVTEX transmissions
message will remain in the store for more than two weeks before they are overwritten.
After using the NAV6 for a while you may notice that if you receive a particular message more
than once there will only ever be one copy in view. If a message has been received more than
once the NAV6 will store only the best version. It even attempts to repair corrupted messages
by comparing repeated transmissions of the same message!
Filter Profiles
The messages currently available for viewing on screen are selected from the messages stored
in memory by applying ‘filter profiles’.
To see the current selected filter profile select Settings, the profile selected is displayed at the
top, next to NAVTEX in the Settings Menu.
There are three profiles on the standard NAV6 and 5 on the NAV6plus. Each profile has 4
setup pages for 518kHz Stations, 518kHz Message Types, 490kHz Stations and 490kHz
Message Types. On the NAV6plus profile 5 is also used to control which messages are
automatically printed or sent to the serial interface (see the settings Menus section for more
information).
In the Settings Menu or any one of the filter pages press Next Prof to change to the next
profile number. You will notice that the settings on the screen change with filter profile
number. The last profile selected in the Settings Menu is the one that will be used when you
return to the NAVTEX message view.
You can customise the Filter Profiles so that you can switch quickly between set ups for
different viewing requirements, perhaps for sailing in specific areas or viewing particular types
of messages.
By default the NAV6 is preconfigured with some useful Filter Profiles. You can reset any of the
Filter pages back to the defaults at any time by pressing the Reset button on the Settings
page.
Tip: Use profile 1 for normal operation and use the other profiles if you want to switch between
different sets of messages on the display.
Station Selection
If you leave your NAV6 receiving for a long time you will have received many messages
(subject to your current location) and unless you
filter out those stations that are not required for
display, you will be swamped with data.
You can show or hide messages from required
stations by turning them on and off manually in
the Station Filter pages. On NAV6plus the
stations displayed can also be selected
automatically using position information from a
GPS receiver.

NAV6 Series NAVTEX System User Guide
12
Station Filter selection is made in the Station Filter Pages accessed from the Settings Menu.
You will notice that each station can be set to one of three filter settings:
Setting
Operation
On
Messages from station always in view (see note 1)
Off
Messages from station never in view
Auto
Messages from station only viewed when nearest or in range
depending upon setting (see note 1)
Note 1: messages are only displayed if they also fall within the ageing limit, error limit and
message category filter settings.
An asterisk to the right of the station name indicates that the station is enabled for viewing
with the current filter setting and location.
Automatic Station Selection Using GPS (NAV6plus only)
Many users will just want to display NAVTEX from the closest NAVTEX station to their cruising
location. This can easily be achieved by connecting a GPS and setting the Auto Station Filter.
The setting can be set to Nearest or In Range.
Nearest
With Nearest selected only messages from the station closest to your position will be
displayed.

NAV6 Series NAVTEX System User Guide
13
In Range
NAVTEX stations have a declared transmission range which is stored in your NAV6’s station
database. With ‘In Range’selected all messages from the stations that are in range of your
current position will be displayed.
Tip: Set stations that you want to ‘automatically select’to Auto, and stations that you definitely
do not want should be set to Off. You may wish to set your ‘home’ station to On so that you
display messages from it even if it is currently not the nearest station to your cruising position.
Important (NAV6plus Only): You may wish to leave your NAV6plus running whilst your GPS
or instrument system is disconnected or switched off. If you do this then please be aware that
the Navigate data items derived from NMEA (including position) will time out after a short
while. If you have also opted to display only the ‘Nearest’ NAVTEX station or stations ‘In
Range’ then the NAV6plus will no longer have the required position data. It will revert to
displaying all stations that are set to ‘Auto’. As soon as the NMEA data becomes available
again only the ‘Nearest’ or ‘In Range’ stations will be displayed dependent upon your current
settings.
Manual Station Selection
You can manually select a station (or stations) by setting them to On or Off by using the UP
and DOWN keys to select them then the and Softkeys 2and 3or RIGHT key to toggle the
setting. If you are using a GPS but still want to select stations manually then do not leave any
stations set to Auto.
Message Type Filtering
You can further reduce the amount of unwanted messages
that are displayed by applying a filter to the message types.
Select the Message Type Filter Page from the Settings
Menu.
Each message type can be turned On or Off or can be set to
New using the UP, DOWN, and and Softkeys 2and 3to
toggle the setting.
The figure shows the 518kHz Message Types Filter Page; the
490kHz Types filter page is similar.
Each of the message types can be selected as either On, Off
or New
Set each message type filter to one of the following:
Setting
Notes
On
Message type always displayed
Off
Message type never displayed
New
Message type only displayed when new. Messages marked as read will
not appear.

NAV6 Series NAVTEX System User Guide

Reading ‘NEW’ Messages
Sometimes it is useful to know which messages have been received since you last looked at
the NAV6 display. You may have noticed that each message header carries a ‘NEW’ icon and
that there is an additional ‘NEW’ icon in the status bar at the top of the display. Select the
NAVTEX View and you will see that Softkey 3 is now indicated as Next New. If the message at
the top of the display has the ‘NEW’ icon showing then Softkey 2 will now be indicated as
Mark Read. Once you have read the message and want to de-emphasise it then press Mark
Read. The ‘NEW’ icon will disappear from the message header. Press Next New to jump to the
next new message. Proceed through all of the messages in this way. Once all of the messages
have been marked as read then the ‘NEW’ icon at the top of the display will also disappear.
When you return to the NAV6 later on it is now very easy to tell if there are any new messages
to read (the ‘NEW’ icon will be shown in the status bar at the top of the display).
Note that messages that have been marked as read will still be displayed, but with the ‘NEW’
icon removed from the message header. It is possible to hide messages once they have been
read; go to the Message Type Filter Page and set the message types that you want to hide
after they have been marked as read to ‘New’ instead of ‘On’. You may wish to leave SAR
messages as ‘On’ so that they are not hidden once read.
Displaying the Newest Message
All messages are date and time stamped by the NAV6 even if there is no GPS connected and
therefore no correct source of time data.
If there is no GPS connected then you can manually enter the time and date or just ignore it.
The NAV6 will still order the messages in the correct chronological order (remember that the
indicated time of reception will be incorrect).
Messages are displayed in the NAVTEX View in time descending order i.e. the newest
messages will appear at top of the display.
Message Ageing
NAVTEX messages become less relevant over time and eventually just clutter the display. In
order to reduce the number of obsolete NAVTEX messages that are being displayed, the
NAV6 uses a message ‘Age Limit’.
The NAV6 will hide messages that are older than a certain pre-settable age limit. These
messages are still stored in the NAV6plus memory for a considerable time after they have
been removed from the display and can still be displayed if necessary by increasing the
message age limit setting.

NAV6 Series NAVTEX System User Guide
15
To change the age limit select NAVTEX Settings from the Settings Menu. Select Age Limit
using the UP and DOWN keys and then the and Softkeys 2and 3to select a value. The
default setting is three days which is the official time that NAVTEX messages remain valid.
Set a longer age limit or none if you wish to display NAVTEX messages going back over the
previous weeks.
NAVTEX View
The NAVTEX View is only available if a receiver is
(or has been) connected to the display and the
NAVTEX frequency setting on the NAVTEX options
page is set to 518kHz, 490kHz or Both.
Viewing NAVTEX Messages
In the NAVTEX View, the display consists of a large
area dedicated to displaying NAVTEX messages,
with a status bar at the top, and descriptions of the
Softkey functions at the bottom.
It is possible to scroll up and down the messages
line by line, using the UP and DOWN keys. Holding
down these keys will increase the scrolls speed
incrementally to aid moving through the message
store more quickly.
This view can be used for keeping track of new
messages as they are received and displayed. Each
new message can be accessed by pressing Next
New (Softkey 3) and then marked as read, if required by pressing Mark Read (Softkey 2).
The Next New Softkey should be used to move the next new message to the top of the
NAVTEX display, where it can be marked as read by pressing Mark Read. Note that the
message that will be ‘marked as read’ is indicated in the top left of the status bar. This is
particularly useful when the message’s header has scrolled off the top of the display area.
Printing Individual Messages
If enabled the NAVTEX View allows individual messages to be printed (NAV6plus only). The
Print Softkey is only displayed if the manual print setting is enabled on the NAVTEX Settings
Page. Printing is only possible if an external printer or PC is installed as part of the system.
The Next New Softkey can be used to move the next new message to the top of the NAVTEX
display where pressing Print will send it to the printer.

Navigation Views
(NAV6plus or NAV6repeater only)
Navigate Views are only available if there is a GPS or other source of NMEA 0183 data
connected to the NAV6plus or NAV6repeater NMEA input.
The GPS icon in the status bar at the top of the display will be illuminated only if there is
position data available on the NMEA input.
There are six fixed-format Navigate Views and four Custom Views. These can be selected on
the General Settings Page.
The six fixed views are:
Barometer View
Combined View
Position View
Waypoint View
Conning View
Log View
The user configurable views are Custom 1,2,3 and 4.
Note: Data fields that are not available on the NMEA input are indicated by a series of dashes
(e.g. ---.--).
Important
The correct magnetic variation must be input at the navigation instruments (e.g. GPS,
electronic compass) for the accurate display of COG, set, waypoint bearing and heading.
For the purposes of testing your installation, you may wish to use your GPS’s simulator mode
to generate data for the NAV6plus. Please check your GPS User Manual to find out whether it
transmits valid NMEA data whilst it is in its simulator mode –many GPS’s do not set the ‘data
valid’ flag in the NMEA sentences during simulation. As a safety feature, the NAV6plus will
indicate that it is receiving unreliable NMEA data by displaying the GPS icon with a line
through it in the status bar at the top of the display.
The NAV6plus also has a built in NMEA simulator mode –please ensure that it is switched
OFF in normal operation.

and a graphical “rolling road” display of the boat position and
course relative to the course line. The rolling road display can
be used to steer the boat along the course line whilst keeping
the cross track error within chosen limits (the XTE limit may be
changed on the Navigate Settings Page. The Waypoint View
shows the waypoint name, waypoint position, time to go (TTG
in hours, minutes and seconds), range and bearing to

Conning View
The Conning Display is a unique analogue display which
shows overlapping vectors for Heading (course through the
water), Course Over the Ground (COG), Set (a combination of
leeway and tide) and wind. All of these vectors are displayed
relative to the current heading, which is displayed in digital
form at the top of the screen.
Heading is shown as a single headed arrow; Course Over the
Ground (COG) is shown as a double headed arrow, and Set is
shown as a triple headed arrow - in the familiar manner. The
wind vector displays variable tail patterns according to the
strength of the wind. It follows the usual meteorological wind
symbol rules: 5 kts per half feather, 10 kts per full feather, 50
kts per triangle. Computed Set and Drift and other related
parameters are shown in digital form at the bottom of the
screen.
To take into account various sea states, variable damping levels may be selected by pressing
Damping Softkey 2. The currently selected level is shown in the top right hand corner of the
display. The damping level can be None, Low, Medium or High. The damping level affects
COG, SOG, Heading and Water Speed and Set and Drift readings.
The UP and DOWN keys have no function in this View.

The Log View columns are Position, COG, SOG,
Heading, Water Speed, Wind Direction, Wind
Speed, Depth and Distance.
Printing the Log
In the Navigation Settings you can set the Log to automatically print new log entries and you
can also enable manual printing of the log. If Auto Print is set on then whenever a new log
entry is created it will be output on the serial connection. If Manual Print is set to on and the
Log View is scrolled fully left the Softkey 2 will be replaced with a Print button. Pressing the
Print Softkey will send ALL Columns of the current page of log data to the serial connection.
Custom Views
The four Custom Views can be configured to show either
2, 3 or 4 panels (the figure shows a 3 panel view). Each
panel can be configured to show different navigation
information from a range of options.
See the Customs Views Page under Navigate in the
Settings Menu for more details of the available options.
