6I3 STAT.] IMULTILATE RAL-TELEC()OMMUINICATIONS-OCT. 2 , 1947 (Chapter XII, art. s3RR) (M9-M4) 849§8. When practicable, the hours of service of ship sta- tions of the third category may be mentioned in the List of Coast and Ship Stations. 850 §9. As a general rule, when a coast station has traffic on hand for a ship station of the third category not having fixed hours of service and assumed to be within range of the coast station, the latter calls the ship station during the first half-hour of the first and third periods of service for ships of the second category performing an eight-hour service, in accordance with the provisions of appendix 13. 851 § 10. For the international service of public correspon- dence, ship stations equipped exclusively for the use of radio- telephony constitute a single category. These stations carry on a service the duration of which is not determined by these Regulations. 852 § 11. (1) Ship stations whose service is not continuous may not close before: 853 a) finishing all operations resulting from a distress call, urgency or safety signal; '54 b) exchanging so far as practicable all traffic orig- inating in or destined for coast stations situated within their range and mobile stations which, being within their range, have indicated their presence before the actual cessation of work. 855 (2) Any ship station not having fixed working hours must inform the coast stations, with which it is in communi- cation, of the time of closing and the time of reopening its service. 856 § 12. (1) a) Any mobile station arriving in port, and whose service is therefore about to close, must so notify the nearest coast station and, if necessary, the other coast stations with which it generally com- municates. 1893
