Citation 1. This standard may be cited as Radiocommunications Standard 302 (Cordless Telephones) (Revised 1991).
Interpretation 2. In this standard, unless the contrary intention appears: “base station” means a base radiocommunications transmitter and receiver station of a cordless telephone to which this standard applies; “cellular mobile telephone service” means a radiocommunications service consisting of: (a) 1 or more handsets; and (b) 2 or more base stations forming part of a public mobile telephone service where the area served by each base station (in this definition called a “cell”) is restricted; and (c) 1 or more stations (in this definition called “mobile switching centres”) which: (i) are able to communicate by means of radiocommunications with; or (ii) are connected by a line to; 2 or more base stations and a public switched telephone network; being a service where: (d) the operator of a handset may communicate with another user of the public switched telephone network by means of radio signals between the handset and a base station; and (e) as the operator of the handset moves from the cell of 1 base station into the cell of an adjoining base station—a mobile switching centre redirects the signals from the handset so that the signals that would otherwise have been channelled through the first-mentioned base station are channelled through the adjoining base station; “channel” means a 25 kHz band centred on the nominal carrier frequency of a base station or handset;

“cordless telephone” means a telephone consisting of: (a) a base station connected by means of a line to a public switched telephone network; and (b) one or more handsets none of which is connected by a line to the fixed base station but by means of which communication may be achieved through the fixed base station with the users of other telephones in the public switched telephone network by the transmission of radio signals between the handset and the fixed base station; “dB” means decibel; “dBuV/m” means decibel relative to one microvolt per metre; “device” means a device to which this standard applies; “emission” means radiation produced, or the production of radiation, by a radiocommunications transmitter; “kHz” means kilohertz; “line” has the same meaning as in the Telecommunications Act 1989; “MHz” means megahertz; “mW” means milliwatt; “out-of-band emission” means an emission on a frequency or frequencies outside the permitted bandwidth which results from the modulation process and excludes spurious emissions; “permitted bandwidth” means the 16 kHz band centred on the carrier frequency on which the radiocommunications transmitter is operating; “radiation” means the outward flow of energy from any source by means of radio transmission: “RS” means Radiocommunications Standard; “spurious emission” means an emission on a frequency or frequencies which are outside the permitted bandwidth and the level of which may be reduced without affecting the corresponding transmission of information; “standard AC mains network” means a network which, when inserted into the AC mains lead of a cordless telephone, has a nominal impedance of 50 ohms at the operating frequency of base station transmitters operating on a carrier frequency not exceeding 2 MHz; “standard device” means a device which complies with this standard; “station” means an installation or thing that is, or includes, a radiocommunications transmitter or receiver; “unwanted emission” means a spurious emission or an out-of-band emission.

(2) This standard does not apply to: (a) cordless telephones designed or intended to operate in a cellular mobile telephone service; or (b) cordless telephones designed or intended to operate on frequencies within the band 861 MHz to 865 MHz inclusive.
PART 2—GENERAL
Equipment markings 4. (1) Subject to subclause (4), there must be displayed on a device: (a) a compliance statement which: (i) consists of the words: “COMPLIES WITH RS 302(1990) TYPE APPROVAL No.”; and (ii) the type approval number shown on the compliance statement certificate issued in respect of the device under section 12 of the Radiocommunications Act 1983; and (b) its type or model designation; and (c) the channel designator specified in Column 2 of an item in the Schedule which corresponds: (i) to the nominal carrier frequency of the transmitter base station specified in column 3; and (ii) to the nominal carrier frequency of the transmitter handset specified in column 4; of that item. (2) The type or model designation required under paragraph (1) (b) must: (a) contain the suffix “AUS”; and (b) be used exclusively in relation to that type or model of the device as imported, manufactured or modified for use in Australia in compliance with this standard. (3) For the purposes of paragraph (1)(c), if a device can operate on more than one channel, each channel designator:

(a) specified in column 2 of an item in the Schedule; and (b) which corresponds: (i) to the nominal carrier frequency of the transmitter base station specified in column 3; and (ii) to the nominal carrier frequency of the transmitter handset specified in column 4; of that item; must be displayed on the device. (4) A statement or marking displayed on a device in accordance with subclause (1) must be: (a) clearly visible on the exterior surface of the device; and (b) indelible; and (c) tamper proof; and (d) affixed in a manner that prevents it being removed except by defacement or destruction. (5) Paragraph (1)(a) does not apply to a device if the importer, manufacturer or supplier of the device, as the case may be, has not been issued with a compliance statement certificate in respect of the device.
Adjustment mechanisms 5. (1) In this clause, “an adjustment mechanism” means a mechanism which enables the operation of a standard device to be altered so that the device contravenes the requirements of this standard. (2) An adjustment mechanism must: (a) be contained within the housing of a device; and (b) be accessible only with the use of tools.
Conditions of operation 6. (1) The requirements of Parts 3, 4, 5 and 6 must be met by a device when it operates at: (a) ambient temperatures of between 5°C and 40°C inclusive; and (b) primary supply voltages within ±10% of that declared by the manufacturer. (2) The requirements of Parts 4 and 6 must be met by: (a) a device when placed on a non-conducting surface 1.5 metres above the ground with the antenna extended vertically; and
