Foreword
This European Telecommunication Standard (ETS) has been produced by the Electromagnetic
compatibility and Radio spectrum Matters (ERM) Technical Committee of the European
Telecommunications Institute (ETSI).
This ETS has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 83/189/EEC (as amended) laying down a procedure for the provision of
information in the field of technical standards and regulations.
For equipment within the scope of ETS 300 719-1 [15], this ETS, together with ETS 300 719-1 [15], is
intended to become a Harmonized Standard, the reference of which will be published in the Official
Journal of the European Communities referencing the Council Directive on the approximation of the laws
of the Member States relating to electromagnetic compatibility ("the EMC Directive") (89/336/EEC as
amended).
For other equipment, this ETS is intended to become a Harmonized Standard, the reference of which will
be published in the Official Journal of the European Communities referencing the Council Directive on the
approximation of the laws of the Member States relating to electromagnetic compatibility ("the EMC
Directive") (89/336/EEC as amended).
Technical specifications relevant to the EMC Directive are given in annex C.
Transposition dates
Date of adoption of this ETS: 2 January 1998
Date of latest announcement of this ETS (doa): 30 April 1998
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 31 October 1998
Date of withdrawal of any conflicting National Standard (dow): 31 October 1998

1 Scope
This European Telecommunication Standard (ETS) covers the assessment of wide-area paging
equipment and ancillary equipment, in respect of ElectroMagnetic Compatibility (EMC). Technical
specifications related to the antenna port and emissions from the enclosure port of the wide-area paging
equipment are not included in this ETS.
This ETS does not cover ERMES paging receiver equipment.
This ETS specifies the applicable EMC tests, the method of measurements, the limits and the minimum
performance criteria for wide-area paging equipment.
The environment classification used in this ETS refers to the environment classification used in
EN 50081-1 [1], EN 50082-1 [2].
The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus at
residential, commercial and light industrial environments. The levels, however, do not cover extreme
cases which may occur in any location but with low probability of occurrence.
This ETS may not cover those cases where a potential source of interference which is producing
individually repeated transient phenomena or a continuous phenomena is permanently present, e.g. a
radar or broadcast site in the near vicinity. In such a case it may be necessary to use special protection
applied to either the source of interference or the interfered part or both.
Compliance of wide-area paging equipment to the requirements of this ETS, does not signify compliance
to any requirements related to spectrum management or any requirement related to the use of the
equipment (licensing requirements).
Compliance to this ETS does not signify compliance to any safety requirements. However, it is the
responsibility of the assessor of the equipment that any observation regarding the equipment becoming
dangerous or unsafe as a result of the application of the tests of this ETS should be recorded in the test
report.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply:
alignment range: For the purpose of defining the exclusion bands (see subclause 4.7), the alignment
range of the wide-area paging equipment is defined as the frequency range over which the receiver or
transmitter can be programmed and/or re-aligned to operate without any physical change of components
other than programmable read only memories or crystals.
ancillary equipment: Equipment (apparatus), used in connection with a receiver or transmitter, is
considered as an ancillary equipment (apparatus):
- if the equipment is intended for use in conjunction with a receiver or transmitter to provide additional
operational and/or control features to the wide-area paging equipment, (e.g. to extend control to
another position or location); and
- if the equipment cannot be used on a stand alone basis to provide user functions independently of a
receiver or transmitter; and
- if the receiver or transmitter to which it is connected, is capable of providing some intended
operation such as transmitting and/or receiving without the ancillary equipment (i.e. it is not a
sub-unit of the main equipment essential to the main equipment basic functions).
calling function: Transmission of a message via the base transmitter to the pocket receiver in order to
alert and/or inform the carrier of the pocket receiver.

The tests shall be carried out at a point within the specified normal operating environmental range and at
the rated supply voltage for the equipment. The test conditions shall be recorded in the test report.
The test configuration and mode of operation shall be as close to normal intended use as possible and
shall be recorded in the test report.
For immunity tests the test modulation, test arrangements etc., as specified in this ETS in subclauses 4.2
to 4.8 shall apply and the conditions shall be as follows:
- the base transmitter shall operate in the standby mode, except for the radio frequency immunity test
(see subclause 9.2) where the transmitter shall be tested additionally at its maximum rated output
power, modulated with normal test modulation (see subclause 4.2);
- for pocket receivers, the message memory of the receiver memory shall be loaded with
recognisable messages. The receiver shall operate in the standby mode, except for the spot
frequency test of the radio frequency immunity test (see subclause 9.2) where repetitive calls shall
be coupled to the input of the receiver.
4.2 Normal test modulation
The test modulation signal to be used for the calling function shall represent selective messages and
maybe generated by a signal generator or encoded within the equipment. The signal generator used
should be a test signal generator supplied by the manufacturer and capable of generating repetitive c
