EXPLANATORY STATEMENT
STATUTORY RULE 1987 NO. 236 ISSUED BY THE AUTHORITY OF THE MINISTER FOR LAND TRANSPORT AND INFRASTRUCTURE SUPPORT
Sub-section 9(1) of the Radiocommunications Act 1983 (‘the Act’) provides that the Minister may, by instrument in writing, make standards for specified devices or devices included in a specified class of device.
Sub-section 9(2) of the Act provides that before making a standard the Minister shall publish the standard that he proposes to make and invite interested persons to make representations in connection with the proposed standard.
Sub-section 9(5) of the Act provides that standards, relating to radiocommunications transmitters may consist only of such requirements as to -
(a) the performance, design, finish and construction of radiocommunications transmitters; and
(b) markings, warnings, instructions or other statements to be impressed on, worked into, or annexed or affixed to, or to accompany, radiocommunications transmitters,
as are necessary for or in relation to -
(c) the operation of those radiocommunications transmitters;
(d) the prevention of prescribed interference, or risk of prescribed interference, to any other uses or functions of those radiocommunications transmitters; and
(e) the prevention or reduction of interference, or risk of interference, to radiocommunications.
The Minister for Communications published a notice in the Gazette of 13 May 1987 setting out the proposed standard and inviting interested persons to comment on it by 26 June 1987. The proposed standard was also circulated for comment to importers and suppliers. The standard was signed by the Minister for Land Transport and Infrastructure Support on 7 September 1987.
The standard applies to radiocommunications transmitters which are wireless video transmitters. A wireless video transmitter is a device which provides ‘wire free’ connection between video recorders and television receivers, thus allowing a video recorder to operate some distance from one or a number of television receivers. Some wireless video transmitters currently available have a range of up to 100 metres and can cause interference to television reception. The standard will impose requirements which limit such potential for interference. The standard is to come into operation on 2 November 1987.
Part 2 of the standard sets out general requirements for the design of a wireless video transmitter. The requirements restrict access to adjustment mechanisms which could permit operation of the device outside the technical parameters set in the standard (Clause 6) and restrict the size, type and arrangement of antenna which can be used on a wireless video transmitter (Clause 7).
Where a wireless video transmitter has been tested for compliance with this standard, details of the compliance statement certificate and model designation are to be displayed on the wireless video transmitter (Clause 5).
Part 3 of the standard sets the technical requirements for the transmitter in a wireless video transmitter. The transmitter is to be capable of operation only on a UHF frequency, tunable within a specified range, and not on more than one frequency at any one time (clause 9). A maximum limit is set for vision carrier field strength (clause 10) and unwanted emissions (clause 11).
