Displaying the Newest Message
To display the newest message at the top of the display.
Go to [NAVTEX Mode⇒
⇒⇒
⇒SortView⇒
⇒⇒
⇒Descending Order⇒
⇒⇒
⇒Date Criteria].
The newest message is now at the top of the display.
Caution: Messages are 'date and time' stamped even if there is no GPS
connected and therefore no corrected time reference to work from.
When you first power up the NAV6, if there is no GPS connected you should
manually enter the date and time. From then on the ICS NAV6 will keep time
until power is removed from the system.
The NAV6 'Calendar & Clock' stops while power is off consequently the date and
time should be checked and if necessary corrected each time the system is
powered on.
If the correct time and date is not set, messages will still be date stamped in a
chronological order but the indicated time of reception will then be wrong.
Message Ageing
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 NAV6 uses the concept of a message ‘Age Limit’. By setting an age
limit it is possible to hide older messages from view.
Go to [Setup Mode⇒
⇒⇒
⇒NAVTEX View⇒
⇒⇒
⇒Options Page]
Use the UP or DOWN key to move the cursor over the age limit setting, the
LEFT & RIGHT keys to select a new value.
3 days is an appropriate age limit to select as most NAVTEX messages have a
nominal life of 72 hours.
Set a longer age limit if you want to display NAVTEX messages going back over
previous days and weeks.
Remember all messages are still stored in memory for a considerable length of time,
consequently increasing the age limit can bring older messages back into view.
