Nav6 Plus Navtex System User Guide

later on it is now very easy to tell if there are any new messages to

read (the ‘NEW’ icon in the status bar at the top of the display will be

illuminated).

Note that messages that have been ‘marked as read’ will still be

displayed but with the ‘NEW’ icon removed from the header in each

one. However, it is possible to hide messages once they have been

read. Go to [Navtex Mode⇒

⇒⇒

⇒Filter View⇒

⇒⇒

⇒490 or 518 Types Page]

and set the message categories 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 Nav6plus even if

there is no GPS connected and therefore no correct source of time

data.

If there is not a GPS connected then you can manually enter the

time and date or just ignore it. The Nav6plus will still order the

messages in the correct chronological order (remember that the

indicated time of reception will be wrong though).

To display the newest message, go to [Navtex Mode⇒

⇒⇒

⇒Sort

View⇒

⇒⇒

⇒Descending Order⇒

⇒⇒

⇒Date Criteria]. The newest message is

now at the top of the display.

Message Aging

NAVTEX messages become less relevant over time & eventually 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’.

It is possible to 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.

To change the age limit go to [Setup Mode⇒

⇒⇒

⇒Navtex View⇒

⇒⇒

⇒Options

Page] and select the age limit that you require. Use the

UP &

DOWN key to select ‘age limit’ and LEFT & RIGHT keys to select a

value. 3 days is a sensible choice as NAVTEX messages have a

nominal life of 72 hours. Set a longer age limit if you wish to display

NAVTEX messages going back over the previous weeks.
