THE HONG KONG GOVERNMENT GAZETTE, JULY 26, 1929.

NOTE:-Licensees cannot be too careful in carrying out this regulation, as by calling a station which is already engaged in transmission, or calling while other stations are working they are liable to interfere with the communication that is taking place, causing delay to the stations already engaged, and delaying their own messages.
12. The station shall be used in such a manner as to cause no avoidable interference with other stations. In particular reaction must not be used for reception to such an extent as to energise any neighbouring aerial.
NOTE. A general obligation which is imposed on all stations alike, and which is regarded as of the highest importance, is that they shall interfere as little as possible with the working of other stations. The rules of working are largely designed to prevent such interference.
13. Tests and adjustments in the licensee's station must be conducted so as not to interfere with the service of other stations engaged in authorised correspondence. Signals used for testing and adjustment must be of a kind that will cause no confusion with a signal, abbreviation, &c. having a special meaning defined in the International Radio- telegraph Regulations.
14. When sending any signal for the purpose of tests, adjustments or experiments the licensee must, during the course of transmission, emit the call sign at frequent intervals.
15. When it is necessary to send test signals, in order to adjust the licensed apparatus before proceeding with a call or transmission, the signals must not be continued for more than about ten seconds and they must be composed of a series of V's followed by the call sign of the sending station. Similarly, if the station sends test signals at the request of another station to enable the latter to adjust its receiving apparatus, these signals must be composed of a series of V's in which the call sign of the sending station is interpolated several times.
16. The station shall be subject to the control and approval of the Postmaster General, and, together with the record of transmissions, shall be open to inspection at all reasonable times by officers of the Government duly authorised by the Postmaster General.
NOTE:-Duly authorised officers will produce their cards of identity upon request.
17.--(1) The licensee shall not divulge or allow to be divulged to any person (other than a duly authorised officer of His Majesty's Government or of the Government of Hong Kong, or a competent legal tribunal) or make any use whatsoever of any message, both telegraphic and telephonic, received by means of his apparatus, except messages in connection with his experiments received from another experimental station. The inter- ception of radioelectric correspondence other than that which the station is authorised to receive is strictly forbidden, and where such correspondence is involuntarily received it must not be reproduced, transcribed, communicated to others or used for any purpose whatsoever.
(2) Not only wireless operators, but all persons who are in a position to become acquainted with the contents of radiotelegrams, are bound to preserve the secrecy of correspondence.
(3) Such operators and persons must preserve secrecy in regard to the contents of, or merely the existence of, correspondence which may be intercepted by wireless stations in connection with which they are employed, as well as in regard to the contents of radio- telegrams which are authorised to be sent or received by the station.
(4) The unauthorised transmission and reception by means of radio installations of correspondence of a private nature, the unauthorised publication or use of correspon- dence received by means of radio installations, and the transmission or placing in circulation of false or deceptive distress signals or distress calls is strictly prohibited.
18. In case of distress the obligation to accept messages is absolute in the case of every station without distinction, and such messages must be accepted with priority over all other messages; they must be answered, and the necessary steps must be taken to give effect to them.
