NAVTEX MESSAGE LOG<br />
The <strong>NAV4</strong>plus keeps an internal log of received NAVTEX message<br />
identifiers to ensure that each message is printed according to the<br />
rules below.<br />
• If a message is received with an error rate of < 33% then it will<br />
be printed only if it hasn’t already been printed with a lower error<br />
rate, within the last 72 hours.<br />
• If a message has been printed with an error rate of < 4% then it<br />
will not be re-printed within 72 hours even if it is received again<br />
with a lower error rate.<br />
The message log is persistent in that it remains in memory even after<br />
the power has been switched off.<br />
Note that if a message is required to be printed after it has already<br />
been received and printed once then the message log needs to be<br />
cleared – see the section entitled ‘<strong>NAV4</strong>plus Set-up’. This is true<br />
even if the power has been switched off for a period.<br />
