Alarms
The message category is used to classify the nature of each NAVTEX message. Of
particular note are message types 'D' (search and rescue), 'A' and 'L' (navigational
warnings) and 'E', 'B' and 'C' (meteorological warnings). When a message with any of
these message categories is received the NAV-7 operates its alarm relay contacts
and transmits an NMEA "ALR" sentence to the currently selected alarm port. The
alarm relay continues to operate until the alarm is acknowledged either by removing
the popup or by reception of an appropriate NMEA "ACK" sentence from another
connected device. Search and rescue messages (category 'D') cannot be read later;
the popup box can only be cleared by pressing the Enter key and reading the
message
.
Finding and viewing NAVTEX messages
The NAV-7 displays NAVTEX messages in several ways designed to make finding
and viewing particular message categories or an individual message easy and
convenient.
