6.2.7 Receiving a message
Reception is possible whenever the terminal is on, indicated by steady light in the ‘Standby’
keyboard indicator. The radio must be set to telex mode and to the desired working channel.
When a call is detected the ‘Called’ keyboard indicator lamp is turned on. In case of paper-
out during reception the connection is terminated.
6.2.8 Example of FEC Transmission
Assuming the GMDSS telex terminal is in Standby and the radio is set up to telex mode and
to the desired frequencies following a DSC
Distress alert call, proceed as follows:
Press Call FEC. The printer responds by printing:
Broadcast FEC or Selective FEC (B/S)?
Press the ‘B’ key. The printer responds by printing:
Broadcast FEC call 2007-06-20 12:30:23, Tx 2174.5 kHz.
The transmission starts, the ‘Tx’ keyboard indicator starts flashing and the control unit
display indicates that the transmitter is delivering RF output to the aerial. When the phasing
sequence (including carriage return, line feed, letter shift) has been transmitted the ‘Tx’ lamp
shines steady light and the printer responds by printing:
>
The communication to follow must be in accordance with the procedures specified for
distress traffic and contain:
•
the distress signal ‘Mayday’;
• the words ‘this is’;
• the 9-digit identity and call sign or other identification of the ship,
• the ship’s position if not included in the DSC distress alert;
• the nature of distress;
• any other information which may facilitate the rescue.
The connection is terminated by pressing the Break key, then Standby keyboard indicator
lamp starts blinking. After a few seconds transmission stops, the Standby keyboard indicator
lamp shines steady and the terminal is ready to receive.
