 63 STAT.] MULTILATERAL-TELECOMMUNICATIONS-OCT. 2, 1947 (Chapter XIII, art. 30 RR) (691-648) they use for this purpose must be stated in the List of Coast and Ship Stations. 691 (7) Mobile stations which hear their call sign during this transmission must reply as soon as they can do so, fol- lowing as far as possible the order in which they are called. 692 (8) When the traffic cannot be sent immediately, the coast station informs each mobile station concerned of the probable time at which working can begin, and also, if neces- sary, the frequency and class of emission which will be used for working with it. 693 §4. When a land station receives calls from several mo- bile stations at practically the same time, it decides the order in which these stations may transmit their traffic. This deci- sion is based solely on the necessity for allowing each of the- calling stations to clear the greatest number of radiotele- grams. 694 § 5. (1) When a station called does not reply to a call sent three times at intervals of two minutes, the calling must cease and must not be renewed until after an interval of fifteen minutes. 695 (2) However, in the case of a communication between a station of the maritime mobile service and an aircraft sta- tion, calling may be renewed after an interval of five minutes. 696 (3) Before renewing the call, the calling station must ascertain that the station called is not in communication with another station. 697 (4) The call may be repeated at shorter intervals if there is no reason to believe that it will interfere with com- munication in progress. 698 § 6. (1) When communication is first established with a land station, any mobile station may, if it deems it advisable in. order to avoid confusion, transmit its name in full. 1847
