pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in

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 the first part of a multi-part standard, the titles of which are:
Part 1: Technical characteristics and methods of measurement;
Part 2: Harmonized EN covering essential requirements under article 3.2 of R&TTE Directive.
Every EN prepared by ETSI is a voluntary standard. The present document contains text concerning the type approval
of equipment to which it relates. This text does not make the present document mandatory in its status as a standard.
However, the present document can be referenced, wholly or in part, for mandatory application by decisions of
regulatory bodies.
The national regulations on Citizens' Band (CB) equipment that permit the use of other types of modulation or power
levels will not necessarily be affected by the adoption of the present document.
National transposition dates
Date of latest announcement of this EN (doa): 31 March 2001
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 30 September 2001
Date of withdrawal of any conflicting National Standard (dow): 30 September 2001
Introduction
The present document is intended to specify the minimum performance and the methods of measurement of CB Double
Side Band (DSB) and/or Single Side Band (SSB) amplitude modulated radio equipment 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.
Administrative arrangements (e.g. for type approval, marking, antennas), and conditions for the use of CB DSB and/or
SSB amplitude modulated radios are to be determined by the national regulatory authorities.
The present document may 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 standard
contains instructions for the presentation of equipment for type testing purposes (clause 4), conditions (clauses 6 and 7)
and measurement methods (clauses 8 and 9).

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 should be tested in accordance with the methods
specified in the present document.

1 Scope
The present document applies to Double Side Band (DSB) and/or Single Side Band (SSB) amplitude modulated
Citizen's Band (CB) radio equipment operating in the frequency band 26,960 MHz to 27,410 MHz with a channel
spacing of 10 kHz, and intended for analogue speech and/or data transmission.
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 that may be required by a user, nor does it
necessarily represent the optimum performance achievable.
The present document covers base stations, mobile stations and two categories of hand-portable stations.
The present document is complementary to ETS 300 135 [1] which concerns angle modulated CB radio equipment
(CEPT PR 27).
Any CB equipment covered by the present document that can also work with angle modulation is also required to meet
ETS 300 135 [1].
The present document is based upon existing national standards.
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 that is intended for use with either an integral antenna or an external antenna, the equipment is
specified to be measured as equipment intended for use with an external antenna and specified to meet the appropriate
limits. In addition to this the following characteristics of the transmitter and receiver are specified to be measured as for
equipment for use with an integral antenna and the appropriate limits are defined:
- transmitter carrier power;
- spurious emissions of the transmitter;
- spurious radiation of the receiver.
