    Short feature description Introduction The member number has a similar meaning as the return address on an envelope. The member number is used by the ves - s el/vehicle surveillance centre to identify the transceiver that transmitted the position report. When a position report is received by the Land Earth Station (LES) a DNID file is created from the packets received in the VMS DNID mailbox.

    Some of the features described in this manual are in conflict with the SOLAS GMDSS requirements. Therefore thes e features are not implemented in the TT-3020C SOLAS Fishery Transceiver or in the TT-3028CM Dual Mode SOLAS GMDSS Transceiver. A short list of the missing features are listed in the following. A more comprehensive description of the feature is given in th e rele- vant sections of this manual.
