Important Information
This equipment is not approved for use by SOLAS convention vessels within
the Global Maritime Distress and Safety System GMDSS)
It is intended for use by leisure craft and other non-SOLAS vessels wishing to
participate within GMDSS
Safety Warnings
Do not use the sensor as a grab-handle
This instrument is for use as an aid to sailors and should not lead to a reduction
in the level of good seamanship required at all times
Reception of messages cannot always be guaranteed as this depends on local
radio propagation
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.

1. USER GUIDE
This user guide describes the operation of the NA 6plus, NA 6Aplus, NA 6dual and
NA 6repeater equipments.
Not all the menu features described are provided by the NAV6dual. Where this is
the case, the symbol § is used to mark the feature.
The NA 6repeater will display NA TEX menu pages only when incorporated with a
NA 6 system or NA 6 sensor.
Installation instructions are provided in the separate NA 6 range Installation Guide.
Further installation information is furnished separately with each NA 6 ancillary
instrument. It is recommended that installation be carried out be a recognised marine
installation engineer.
2. QUICK START
You will find the NA 6 extremely easy to operate. Please don't be intimidated by the
comprehensive nature of this manual. In reality, receiving your first NA TEX
messages could not be simpler.
• Follow the installation guidelines
• Re-check the cable connection
• The NA 6 system has no ON/OFF switch; it will start up as soon as power is
applied.
• If you have not connected a GPS navigation receiver, make sure that you set the
date and time on the screen which will appear at start up.
• Wait for your first NA TEX message. If you are within range of a NA TEX
transmitter, you should not need to wait for more than four hours.
• Refer to “Appendix II: NA 6 Menu Navigation” for an overview of the available
operating modes & how they relate to each other.
• Read the “Basic Operation” section to find out how to use some of the commonly
used features of this product
• If you then want to get the best from the system, read the rest of the manual!

3. INTRODUCTION
3. What Is NAVTEX?
NA TEX is a worldwide system for the broadcast and automatic reception of maritime
safety information (MSI) in English by means of a narrow-band direct-printing
telegraphy. NA TEX provides shipping with navigational and meteorological warnings
and urgent information.
NA TEX is an element 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, a
NA TEX receiving capability has become mandatory equipment for certain vessels
under the provisions of the International Convention for the Safety of Life at Sea
(SOLAS).
NA TEX broadcast information is available to all seafarers, free of charge.
3.2 How Does NAVTEX Work?
NA TEX transmissions are sent from stations situated worldwide. The power of each
transmission is regulated 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.

• The NA 6plus and NA 6Aplus can be connected to a printer or computer to print
NA TEX 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.
4.3 NAVTEX Sensor
• The Sensor Unit contains dual receivers that can receive on both 490 kHz and
518 kHz simultaneously.
• The NA 6plus and NA 6dual have a dual channel NA TEX sensor unit.

5 BASIC OPERATION
The NA 6 is a flexible & powerful tool for receiving, storing & viewing NA TEX
messages. To assist you in getting the best from your NA 6 equipment, read this
section which contains short cuts to the most commonly used NA TEX operations.
Read the rest of the manual for a comprehensive guide to the NA 6 range.
First, find your way around the keypad and the display.
Centre keys are a ‘navigation pad’ ( UP DOWN LEFT RIGHT ).
Softkeys are situated on either side of the navigation pad. The current
function is shown on the soft-key menu area at the bottom of the LCD.
The MODE softkey switches between the three operating ‘modes’ (NA TEX,
Navigate & Setup).
The IEW softkey switches between ‘views’ in each operating ‘mode’. If a
‘view’ has several ‘pages’ associated with it then these are selected with the
page softkey.
Operate the keys in this order to get to the mode that you want:
MODE → IEW → PAGE → FUNCTION
Softkeys are context sensitive and cyclical in operation; several button presses will
return you to the start of the cycle. As the button is pressed, the softkey labels change
to show the current functions of the keys.

The Display
At the bottom of the display is the softkey menu area:
The softkey menu area shows what each softkey does in the current operating mode.
The top line of each softkey menu box indicates the option that is currently
selected.
The bottom line of each softkey menu box indicates the current function of
that softkey.
The example above shows the NA 6 in NA TEX Mode; the right softkey selects the
mode, and current mode is Navtex.
At the top of the display is a status bar:
The status information is displayed as a series of icons. The meaning of the icons is
as follows:
Message identifier for the top message
An alarm is active
NMEA / GPS position data available
490 kHz reception available
518 kHz reception available
Receiving message now
Signal Carrier, but no message
Sensor communication fault
SAR message received
