12  Compliance with emission masks
 (1) A person must not operate a radiocommunications transmitter, other than a cellular mobile base station or cellular mobile user equipment, unless the operation of the transmitter:
 (a) complies with emission mask L; or
 (b) complies with emission mask M.
Note 1: Cellular mobile base stations are defined in subsection 4(1) to be radiocommunications transmitters that, when operated, comply with emission mask P. Cellular mobile user equipment is defined in subsection 4(1) to be those radiocommunications transmitters that, when operated, comply with emission mask O. The effect of those definitions and subsection 12(1) is that a radiocommunications transmitter may not be operated in accordance with this instrument unless it complies with one of the four specified emission masks.
Note 2: Section 13 imposes a condition that may affect which emission mask a radiocommunications transmitter must comply with in order to be operated in accordance with this instrument.
 (2) In this instrument, for a radiocommunications transmitter operating using a channel with a particular bandwidth and centre frequency:
 (a) operation of the transmitter complies with emission mask L if, at each fraction of channel bandwidth specified in column 1 of an item of the table below, the attenuation of the transmitter relative to its peak average power, is greater than or equal to the value specified in column 2 of the item;
 (b) operation of the transmitter complies with emission mask M if, at each fraction of channel bandwidth specified in column 1 of an item of the table below, the attenuation of the transmitter relative to its peak average power, is greater than or equal to the value specified in column 3 of the item.
