INTRODUCTION

What Is NAVTEX?

What Is NAVTEX?What Is NAVTEX?

What Is NAVTEX?

NAVTEX 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. 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.

the length of the message) and messages can be scrolled with a

single keypress.

•Messages can be filtered and sorted using a number of user

selectable criteria.

•The Nav6plus can act as an NMEA instrument repeater and is

capable of displaying data in a choice of formats.

•The Nav6plus 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.

BASIC OPERATION

BASIC OPERATIONBASIC OPERATION

BASIC OPERATION

The Nav6plus is a flexible & powerful tool for receiving, storing &

viewing NAVTEX messages. In order to assist you in getting the best

from your Nav6plus, read this section which contains short cuts to

the most common NAVTEX operations. Read the rest of the manual

for a comprehensive guide to the Nav6plus.

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 of each softkey is shown on the soft-key menu

area at the bottom of the display.

•The mode softkey switches between the three operating ‘modes’

(Navtex, Navigate & Setup).

•The view 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 →VIEW →PAGE →FUNCTION

Hint : softkeys are context sensitive and cyclical in operation, several

button presses will return you to the start of the cycle.

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 Nav6plus in Navtex Mode; the right

hand softkey selects the ‘mode’ & the 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 ID for the message at the top of the display

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

Viewing & Scrolling Through Navtex Messages

To view Navtex messages you must first select the Navtex Mode.

Use the right hand softkey to change modes until ‘Navtex Mode’ is

visible in the right hand softkey menu box. You can now use the UP,

DOWN, LEFT & RIGHT keys to scroll through the displayed

messages. UP & DOWN scroll line by line, whereas LEFT & RIGHT

scroll message by message.

The messages currently displayed are 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 Nav6plus

has lots of memory so you will easily have enough storage for all

messages received in any 72 hour period. The messages displayed

are selected from the Nav6plus’ memory by applying the current

message filter preset & age limit settings. 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 message filter or age setting.

After using the Nav6plus 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 Nav6plus will store only the best version. It even attempts to

repair corrupted messages using comparing copies of the same

message!

Filter Presets

The messages currently available for viewing on screen are selected

from the messages stored in memory by applying ‘filter presets’.

To see the current selected filter presets go to [Navtex Mode⇒

⇒⇒

⇒Filter

View]. You will notice that the left hand softkey is labelled ‘Preset’

and a number from 1 to 5 is visible. This is the currently selected

filter preset number for the this ‘filter page’. Each of the 4 filter pages

(518 Types, 518 Stns, 490 Types & 490 Stns) has its own 5 presets.

In any one of the filter pages press PRESET to change the preset

number. You will notice that the settings on the screen change with

Nav6 Plus Navtex System User Guide

filter preset number.

Select the preset that you require for the filter page that you are

viewing and then look at the presets for the other filter pages. Note

that the preset that is displayed is the one that is currently applied to

the message display.

Multiple presets can be used for switching quickly between different

sets of messages on the screen. For instance, if you want to show

just ‘navigational warnings from all stations in range’, you can use a

preset to do this.

Although the presets are pre-programmed, you can set them to any

filter setting you require.

Tip : Use preset 1 for normal operation and only use the other

presets if you want to switch between different sets of messages on

the display.

Station Selection

If you leave your Nav6plus receiving for 72 hours 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. This can either be done

automatically using a GPS or by using manual filter settings. In either

case go to [Navtex Mode⇒

⇒⇒

⇒Filter View⇒

⇒⇒

⇒490 or 518 Stns Page]. 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 selected with the current filter setting.
