  • Page 4 NAV6plus NAVTEX System User Guide Congratulations on purchasing this ICS Electronics Ltd product. It is not only an excellent NAVTEX receiver, but a first class instrument repeater. It may be the only display you will ever need at your navigation position.

  • Page 5: Quick Start

    Follow the installation guidelines • Re-check the cable connections • The NAV6plus 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 •...

  • Page 6: Nav6Plus Features

    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.
  • Page 7 BASIC OPERATION BASIC OPERATION BASIC OPERATION The NAV6plus is a flexible & powerful tool for receiving, storing & viewing NAVTEX messages. To assist you in getting the best from your NAV6plus, read this section which contains short cuts to the most commonly used NAVTEX operations.
  • Page 8 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.

  • Page 10 Messages to be displayed are selected from the NAV6plus memory by applying a 'filter preset' and message age limit 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.
  • Page 11 NAV6plus NAVTEX System User Guide...
  • Page 12 NAV6plus NAVTEX System User Guide Filter Presets The messages currently available for viewing are selected from all the messages stored in memory by applying 'Filter View' presets’. There are 5 separate filter view presets, each preset has its own set of 4 'filter page settings'.
  • Page 13 NAV6plus NAVTEX System User Guide • Presets can be used to switch quickly between different sets of messages filter selections. For instance, if you want to show just ‘weather warnings from all stations in range’, you can set up a preset number to do just that.
  • Page 14 NAVTEX station, or only from stations that provide information in their cruising area. This is easily achieved by connecting a GPS receiver and letting the NAV6plus automatically make the best selection. Go to the [NAVTEX Mode⇒ ⇒ ⇒ ⇒ Filter View⇒ ⇒ ⇒ ⇒ 490 or 518 Stns Page].
  • Page 15 NAV6plus NAVTEX System User Guide Note that if a valid GPS position fix becomes unavailable, after a short time delay all 'auto' stations will turn on and remain on until the GPS position returns.
  • Page 16 ‘New’ Messages Sometimes it is useful to know which messages have been received since you last looked at the NAV6plus display. Whenever a message is received the message header box displays a ‘NEW’ or 'SAR' icon. Even if a new message is currently out of view, the status bar at the top of the display will also indicate a ‘NEW’...
  • Page 17 NAV6plus NAVTEX System User Guide • The left hand softkey is now a MARK READ key. Once you have read the ‘NEW’ message and want to clear the ‘NEW’ icon, press MARK READ. The ‘NEW’ icon will disappear from the message header.
  • Page 18 GPS connected and therefore no corrected time reference to work from. When you first power up the NAV6plus, if there is no GPS connected you should manually enter the date and time. From then on the NAV6plus will keep time until power is removed from the system.
  • Page 19 NAVTEX messages become less relevant over time & eventually may just clutter the display. In order to reduce the number of obsolete NAVTEX messages that are being displayed, the NAV6plus uses the concept of a message ‘Age Limit’. • By setting an age limit it is possible to hide older messages from view.

  • Page 20: Advanced Operation
