EXPLANATORY STATEMENT
STATUTORY RULE 1987 NO. 220 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.
Sub-section 9(7) provides that standards relating to receivers may consist only of such requirements as to -
(a) the performance, design, finish and construction of those receivers; and
(b) markings, warnings, instructions or other statements to be impressed on, worked into, or annexed or affixed to, or to accompany, those receivers,
as are necessary or convenient to be made for or in relation to:
(c) the operation of those receivers; and
(d) the prevention or reduction of prescribed interference, or risk of prescribed interference, to any uses or functions of those receivers.
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 3 July 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 2 September 1987.
The standard applies to radiocommunications equipment in headset communicators. A headset communicator incorporates both a radiocommunications transmitter and a receiver. The standard is to come into operation on 1 October 1987.
Part II of the standard sets out general requirements for the design of a headset communicator. 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 and type of antenna which can be used on a headset communicator (clause 7).
Where a headset communicator has been tested for compliance with this standard, details of the compliance statement certificate are to be displayed on the headset communicator (Clause 5).
Part III of the standard sets the technical requirements for the transmitter in a headset communicator. The transmitter is to be capable of operation only on up to 6 specified frequencies and not on more than one of those frequencies at any one time (Clause 10). Maximum limits are set for frequency error (Clause 11), carrier frequency field strength (Clause 12) and unwanted emissions (Clause 13).
Part IV of the standard sets a technical requirement for operation of the receiver in a headset communicator, setting a maximum limit for radiation from the receiver.
