When you are speaking over the radio, you should ensure you:

• speak clearly, so that there can be no confusion with other words;
• speak at normal conversation level, and not shout as shouting may overload the microphone causing distortion;
• pitch the voice at a higher level than for normal conversation; dropping the pitch of the voice at the end of a word should be avoided;
• speak slowly, but still in phrases rather than word by word.

All calls (except the initial Distress, Urgency and Safety calls explained in the following chapters) on the RT follow the same patern.

(The identity of the station called up to 3 times) THIS IS (The identity of the calling station up to 3 times) OVER

(The identity of the station called – spoken once) THIS IS (The identity of the calling station – spoken once) (Message) OVER

Both stations - called and calling - can be identified by their:

• MMSI,
• name, or
• Call Sign.

And both stations can be vessel, CG or CRS.

All the identifications could be used at the same time in a call, but in most cases just one of them is used.

Identifications are spoken:

• 3 times in case of Distress, Urgency or Safety working, in difficult radio conditions, sailing in international or another country's waters (because of the language-pronunciation problem).
  
• twice in case the called station is not expecting the call.
• once in all other cases.
  

But after the contact is established, any identification need only be transmitted once.

RT voice procedure:

• Press the PTT switch and call (using the pattern above) ending with the procedure word “OVER”
• Release the PTT switch and listen for a reply
• When communication is completed finish with the procedure word “OUT”
