1.4 Message numbering
According to [Figure 1-6] of Standard format for NAVTEX messages, each message within a
subject group is allocated a serial number, B3B4, between 01 and 99. This number should be
allocated by the relevant NAVTEX coordinator.
Certain message is allocated [the B3B4 = 00]. Use of this number should be strictly controlled
since messages carrying it will always be displayed in LCD screen, if the broadcast containing
such messages is identified to accept by the receiver. Therefore, the number "00" must only be
used for severely important messages, such as an initial distress message. Routine messages
and service messages should not be allocated to the number
“
00
”
.
All message numbers including "00", are stored in the memory always.
