In the case of radiocompass stations which are grouped, the station called shall notify the other stations of the group and shall in- form the mobile station as soon as the stations of the group are ready to take the bearing. C. After having, if necessary, changed to its new transmitting wave, the mobile station shall reply by sending its call signal combined, when need be, with another signal, during a length of time sufficiently prolonged to permit the bearing to be taken.

If 8. radiocompass station is not satisfied with the operation, it shall request the mobile station to repeat the transmission in- dicated under C. E. As soon as the mobile station has received the result of the observation, it shall repeat the message to the radiocompass station, which shall then state that the repetition is exact or, when necessary, shall correct it by repeating the message. When the radiocompass station is certain that the mobile station has correctly received the message, it shall transmit the signal "end of work." This signal shall then be reJ?eated by the mobile station, as an indIcation that the operation is finished. F. The data concerning (a) the signal to be used to obtain the bearings, (b) the duration of the transmission to be made by the mobile station, and (c) the time used by the radiocompass station in question shall be given in the nomenclature.
