TELECOMMUNICATION COXVENTION. DECEMBER 9, 1932. 2455 interference, frequencies and types of waves in conformity with the rules for allocation and use of waves, as set forth below. [68] § 3. The administrations also agree to assign frequencies to these stations, according to the kind of service they perform, in con- formity with the table of allocation of frequencies (see table below). [00] § 4. In the case where bands of frequencies are assigned to a specific service, the stations of that service must use frequencies sufficiently separated from the limits of these bands so as not to pro- duce harmful interference with the operation of stations belonging to services to which the frequency bands immediately adjoining have been assigned. [01] § 5. (1) The frequencies assigned by administrations to all fixed, land, and broadcasting stations, as well as the upper limit of power contemplated, must be notified to the Bureau of the Union with a view to their publication, when the stations in question carry on a regular service and are capable of causing international inter- ference. Frequencies on which a coast station receives in carrying on a particular service with ship stations using stabilized transmit- ters must also be notified to the Bureau of the Union with a view to their publication. ~'requencies must be selected in such a way as to avoid, so far as possible, interfering with international services belong- ing to the contracting countries and operated by existing stations, of which the frequencies have already been notified to the Bureau of the Union. The aforesaid notification must be made in accordance with the provisions of article 15, § 1 (b) and appendix 6 before the frequency is put into service and sufficiently in advance thereof to allow administrations to take any action which they may deem necessary to insure the efficient operation of their services. [62) (2) (a) However, when the frequency which an adminis- tration intends to assign to a station is outside the bands authorized by the present Regulations for the service involved, this admjnistra- tion shall, in a special report, make the notification mentioned in the preceding subparagraph at least 6 months before this frequency is put into service, and in urgent cases, at least 3 months before that date. (63) (b) The notification procedure laid down above shall also be observed when nn administration intends to increase or to authorize the increase of the power or a change in the conditions of radiation of a station already operating outside the authorized bands, even if the frequency used is to remain the same. [6(] (c) With regard to stations which, when the present Regulations go into force, are already operating outside the bands authorized therein, the frequency and the power used shall be notified immediately to the Bureau of the Union, with a view to their publica- tion, if such a notification has not been made previously. (66] (3) (a) The administrations concerned shall conclude agreements, when needed, for determining the waves to be assigned PO$/, p . 2459. N otiflcation. Post, pp. 2(97, 2 .'iW.
