(2) A licensee shall ensure that:

(a) the emitted frequency of the apparatus is as stable and as free from unwanted emissions as the state of technical development for amateur radio apparatus reasonably permits;

(b) whatever class of emission is in use, the bandwidth occupied by the emission is such that not more than 1% of the mean power of the transmission falls outside the nominal modulated carried bandwidth;

(c) the apparatus is installed, maintained and used so that it does not cause harmful interference to any other radiocommunications apparatus, network or service;

(3) The Authority may require a licensee to modify, restrict in use or permanently close down the amateur station either immediately or on the expiry of such period as may be specified in the event of a national or local state of emergency being declared. The Authority may only exercise this power after a written notice is served on a licensee or a general notice is published on its website.

(4) The licensee shall conduct tests from time to time to ensure that the requirements set out in this regulation are met.

(5) If any harmful interference to other radiocommunications apparatus, network or service is caused by the radiation of unwanted emissions from the apparatus, then the licensee shall suppress the unwanted emissions in accordance with the directions given by the Authority:

Provided that in giving any directions the Authority may determine the extent in relation to which such emissions are to be suppressed.

(6) Neither the Authority nor Government shall be held responsible in any manner whatsoever by the licensee for any harmful interference that may hinder the use or operation of the amateur station used by the licensee.
