Foreword
This European Telecommunication Standard (ETS) has been produced by the European
Telecommunications Standards Institute (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.
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 A.
Other ETSs cover radio communication equipment not listed in the scope.
This ETS is based on EN 50081-1 [2] and EN 50082-1 [3] and other standards where appropriate.

1 Scope
This European Telecommunication Standard (ETS) covers the assessment of on-site paging equipment
and ancillary equipment, used in privately owned and operated paging systems, in respect of
ElectroMagnetic Compatibility (EMC). Technical specifications related to the antenna port and emissions
from the enclosure port of the radio equipment are not included in this ETS. Such technical specifications
are found in the radio product standard ETS 300 224 [1].
This ETS specifies the applicable EMC tests, the method of measurements, the limits and the minimum
performance criteria for on-site paging equipment, as specified in ETS 300 224 [1], operating on
frequencies between 9 kHz and 470 MHz and the associated ancillary equipment.
The environment classification used in this ETS refers to the environment classification used in the
Generic Standards EN 50081-1 [2], EN 50082-1 [3].
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 radio 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.

ETS 300 682: June 1997
For immunity tests the test modulation, test arrangements etc., as specified in this ETS, subclauses 4.2 to
4.11 shall apply and the conditions shall be as follows:
- the base transmitter shall operate in the standby mode, except for the spot frequency test of the
radio frequency electromagnetic field immunity test (subclause 9.2) where the transmitter shall be
operated at its maximum rated output power, modulated with normal test modulation
(subclause 4.2);
- the standby mode of the base transmitter is the mode of operation in which the transmitter is ready
to transmit, waiting for a start control signal to actual start transmitting;
- 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 electromagnetic field immunity test (subclause 9.2) where
repetitive calls shall be coupled to the input of the receiver;
- the standby mode of the pocket receiver is the mode of operation in which the receiver is capable of
receiving calls;
- for pocket transmitters, the transmitter shall operate unmodulated (if possible) at its maximum rated
output power. If unmodulated operation is not possible, the manufacturer shall specify the method
of performance assessment and the acceptable degradation of performance;
- the standby mode of the pocket transmitter is the mode of operation in which the transmitter is
ready to transmit waiting for a command from the press to transmit button;
- for the base receivers, the wanted Radio Frequency (RF) input signal shall be unmodulated.
The standby mode of the base receiver is the mode of operation in which the receiver is capable to
receive.
4.2 Normal test modulation
The test modulation signal, to be used for the calling function, is a signal representing selective messages
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 calls. For
transmitters not having a modulation input port the internal equipment modulation shall be used, and a
repetitive call possibility shall be available.
The talk-back facility shall be tested with an unmodulated carrier, if possible.
4.3 Arrangements for test signals at the input of the base transmitter
The signal generator to be used for the normal test modulation (subclause 4.2) shall be located outside
the test environment and connected to the modulation input port of the transmitter. Adequate measures
shall be taken to protect the measuring equipment from the effect of all the radiated fields within the test
environment.
4.4 Arrangements for test signals at the output of the base transmitter
Where the transmitter incorporates an RF antenna connector, the output signal shall be delivered from
that connector by a shielded transmission line, such as a coaxial cable, to the receiving/measuring
equipment outside of the test environment.
Adequate measures shall be taken to avoid the effect of unwanted signals on the measuring equipment.
Where the transmitter does not incorporate an RF connector, the output signal shall be delivered from the
transmitter to an antenna located within the test environment. This antenna shall be connected by a
shielded transmission line, such as a coaxial cable, to the measuring equipment located outside of the test
environment.

ETS 300 682: June 1997
For the spot frequency test of the radio frequency electromagnetic field immunity test (subclause 9.2) the
measuring equipment should be a paging receiver and repetitive calls shall be transmitted and coupled to
the input of the paging receiver located outside the test environment.
4.5 Arrangements for test signals at the input of the pocket receiver
The manufacturer shall at the time of submitting the equipment for testing, supply, if necessary, a test
fixture and a message generator to generate the wanted input signal.
The source of the wanted input signal, modulated with normal test modulation (subclause 4.2), shall be
located outside the test environment and the signal level used shall be chosen to a value significantly
above the threshold sensitivity but below the overload characteristics of the receiver (the suggested value
is 60 dB above the threshold sensitivity, if possible). Adequate measures shall be taken to protect the
measuring equipment from the effect of all the radiated fields within the test environment.
Where the receiver incorporates an RF antenna connector, the RF signal source shall be coupled to the
input of the receiver via a shielded transmission line such as a coaxial cable.
Where the receiver does not incorporate an RF connector, the RF signal source shall be presented to the
receiver from another antenna located within the test environment. This antenna shall be coupled to the
RF signal source via an adjustable attenuator.
4.6 Arrangements for test signals at the output of the pocket receiver
From the performance check before and after the test it shall be possible to assess the performance of
the pocket receiver from the presented messages and/or the call received alert signal(s) of the receiver.
During the spot frequency test of the radio frequency electromagnetic field immunity test (subclause 9.2)
the call received alert signal output of the receiver shall be coupled to the outside of the test environment
and it shall be possible to assess the performance of the equipment from the call received alert signal(s)
of the receiver.
4.7 Arrangements for test signals at the output of the pocket transmitter
The measuring equipment used to monitor the output signal of the transmitter shall be located outside the
test environment. Adequate measures shall be taken to protect the measuring equipment from the effect
of all the radiated fields within the test environment.
Where the transmitter incorporates an RF antenna connector, the output signal of the transmitter shall be
coupled to the measuring equipment via a shielded transmission line such as a coaxial cable.
Where the transmitter does not incorporate an RF connector, the output signal of the transmitter shall be
coupled to an antenna located within the test environment. This antenna shall be coupled by a shielded
transmission line to the measuring equipment located outside of the test environment.
4.8 Arrangements for test signals at the input of the base receiver
The source of the wanted input signal shall be located outside the test environment and the signal level
used shall be chosen to be a value significantly above the threshold sensitivity but below the overload
characteristics of the receiver (the suggested value is 60 dB above the threshold sensitivity, if possible).
Adequate measures shall be taken to protect the measuring equipment from the effect of all the radiated
fields within the test environment.
Where the receiver incorporates an RF antenna connector, the RF signal source shall be coupled to the
input of the receiver via a shielded transmission line such as a coaxial cable.
Where the receiver does not incorporate an RF connector, the RF signal source shall be presented to the
receiver from another antenna located within the test environment. This antenna shall be coupled to the
RF signal source via an adjustable attenuator.
