This Standard applies to Short Range Devices (SRDs) commonly used for radiocommunications in Australia and New Zealand. Examples of SRDs are: alarms, baby monitors, garage door openers, data collection systems, retail and logistic systems, telecommand applications, wireless home data telemetry and/or security systems, and keyless automobile entry systems. SRDs use all types of modulation, may be fixed, mobile or portable and have dedicated, and/or integral antennas.In Australia and New Zealand, SRDs may be referred to as Low Interference Potential Devices (LIPDs). In New Zealand, before 2002, SRDs were known as Restricted Radiation Devices (RRDs).This Standard specifies the minimum performance and methods of measurement for Short range devices supplied for use under the following radiocommunications licences:(a) Australia The Radiocommunications (Low Interference Potential Devices) Class Licence 2000 and the Radiocommunications (Radio-controlled Models) Class Licence 2002. Other requirements also exist under the Radiocommunications Compliance and Labelling scheme.(b) New Zealand The Radiocommunications Regulations (General User Radio Licence for Short Range Devices) Notice hereafter referred to as the General User Radio Licence or GURL.SRDs can expect to be sharing radiofrequency spectrum with other radiocommunications devices. It is a condition of operation of an SRD that harmful interference should not be caused to the operation of other radiocommunications devices. If operation of an SRD causes harmful interference to authorized radiocommunications services, even if the SRD complies with all of the technical Standards and equipment authorization requirements in the National rules, the user of that device is in breach of the conditions of operation of that device. As well, SRDs are not afforded protection from interference caused by other radiocommunications services.
