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
plus 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.
