Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee

Foreword
This European Standard (Telecommunications series) has been produced by ETSI Technical Committee
Electromagnetic compatibility and Radio spectrum Matters (ERM).
The present document is part 1 of a multi-part EN covering the Electromagnetic compatibility and Radio spectrum
Matters (ERM); Angle-modulated Citizens Band radio equipment (CEPT PR 27 Radio Equipment), as identified below:
Part 1: "Technical characteristics and methods of measurement";
Part 2: "Harmonized EN covering essential requirements under article 3.2 of R&TTE Directive".
The present document concerns only angle modulation. The existing national Citizens' Band standards or specifications
which also permit the use of other forms of modulation (including amplitude and single sideband) will not be affected by
the adoption of the present document.
The present document is based upon CEPT Recommendation T/R 20-02 [1], originally prepared by the CEPT R22
Committee for use by Citizens' Band (CB) radio equipment.
Angle modulation shall be used for radio equipment covered by the present document, with an audio pre-emphasis
characteristic for the transmitter, and audio de-emphasis for the receiver.
Administrative arrangements (e.g. for type approval, marking, antennas), and conditions for the use of CB angle
modulated radio (CEPT PR 27) are to be found in CEPT Recommendations T/R 20-02 [1] and T/R 20-07 [2].
Every ETS prepared by ETSI is a voluntary standard. The present document contains text concerning type approval of
the equipment to which it relates. This text should be considered only as guidance and does not make the present
document mandatory.
The technical specifications relevant to the EMC Directive are listed in annex C.
National transposition dates
Date of latest announcement of this EN (doa): 31 October 2000
Date of latest publication of new National Standard

Introduction
The present document is intended to specify the minimum performance and the methods of measurement of Citizens'
Band radio equipment (CEPT PR 27) as specified in the Scope.
Clause 5 provides the corresponding limits. These limits have been chosen to ensure an acceptable grade of service and
to minimize harmful interference to other equipment and services.
The present document will also be used by European notified accredited test laboratories for the assessment of the
performance of the equipment. In order to avoid any ambiguity in that assessment, the present document contains
instructions for the presentation of equipment for type testing purposes (clause 4), measurement methods (clauses 8 and
9) and conditions (clauses 6 and 7).
The present document was drafted on the assumption that:
a) the type test measurements would be performed only once in one of the accredited test laboratories, and then
accepted by the various authorities in order to obtain type approval;
b) if equipment available on the market is required to be checked it shall be tested in accordance with the methods
specified in the present document. The present document covers base stations, mobile stations and two categories
of hand-portable stations.

1 Scope
The present document covers the minimum characteristics considered necessary in order to make the best use of the
available frequencies. It does not necessarily include all the characteristics which may be required by a user, nor does it
necessarily represent the optimum performance achievable. It applies to angle modulated Citizens' Band radio
equipment (CEPT PR 27) operation in the frequency band 26,960 MHz to 27,410 MHz with channel separations of
10 kHz, and intended for analogue speech.
The present document applies to equipment with a socket for an external antenna and to equipment with an integral
antenna.
In the case of equipment which is intended for use with either an integral antenna or an external antenna, the equipment
shall be measured as equipment intended for use with an external antenna and shall meet the appropriate limits. In
addition to this, the transmitter characteristics:
- transmitter carrier power;
- spurious emissions of the transmitter;
and the receiver characteristic:
- spurious radiations of the receiver;
shall be measured as for equipment for use with an integral antenna and the appropriate limits shall be met.
