Foreword
This draft Harmonised European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic
compatibility and Radio spectrum Matters (ERM), and is now submitted for the combined Public Enquiry and Vote
phase of the ETSI standards EN Approval Procedure.
The present document has been prepared under the Commission's standardisation request C(2015) 5376 final [i.18] to
provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation
of the laws of the Member States relating to the making available on the market of radio equipment and repealing
Directive 1999/5/EC [i.14].
Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with
the normative clauses of the present document given in table A.1 confers, within the limits of the scope of the present
document, a presumption of conformity with the corresponding essential requirements of that Directive and associated
EFTA regulations.
The present document is part 4 of a multi-part deliverable covering Wireless Microphones, Audio PMSE up to 3 GHz,
as identified below:

Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Executive summary
With the introduction of Directive 2014/53/EU [i.14], the present multi-part deliverable has been reformatted into
multiple parts to accommodate the different types of equipment represented, i.e. different receivers for audio
Programme Making and Special Events (PMSE); and Assistive Listening Devices (ALDs). Part 4 covers Assistive
Listening Devices including personal sound amplifiers and inductive systems with digital and analogue (FM) receivers.
It is also applicable to accessories associated with ALDs. In addition, it covers ALDs with inductive receivers (T-coils).
Introduction
With the introduction of Directive 2014/53/EU [i.14], receiver parameters are now included and the removal of the 9
kHz lower limit has brought inductive loop systems and receivers into the present document. Inductive loop transmitters
are covered within ETSI EN 303 348 [i.19] along with test receivers; hearing aids containing inductive loop receivers
(often referred to as T coil) are now covered in clause 9.2 of the present document. The frequency range of the present
document has been reduced to accommodate inductive loop receivers.
The present document is a testing standard based on spectrum utilization parameters and does not include performance
characteristics that may be required by the user nor requirements for interfacing equipment.
ETSI EN 300 422 [i.2] was originated in 1991 when Assistive Listening Devices (ALD) were a very small part of the
Radio Microphone Industry; in recent years major advances in both the volume and functionality of ALDs has caused a
rethink in how to best present the testing regime in a clear and concise manner. After a number of discussions, the
present ETSI EN 300 422 family [i.2] covers audio PMSE as Parts 1 [i.20], 2 [i.21], and 3 [i.22]; and ALDs as Part 4
(the present document).
Systems including assistive listening devices (Aids for the handicapped) with digital modulations and operating in the
range 863 MHz to 865 MHz may be tested to either the present document or to ETSI EN 301 357 [i.1] with due
consideration of power and operating frequency.
Ear worn hearing assistance devices may in some cases require stereo transmission to present both left and right audio
information to the wearer. For that reason, devices that transmit information to the hearing impaired may require two
channel operation. It is expected that two or more channel devices will be tested separately when determining
bandwidth and associated measurements. Channels may involve the use of two separate frequencies or wider
bandwidth.
Additional standards or specifications may be required for equipment:
1) intended to interface to Public Networks, e.g. PSTN. This facility may be subjected to regulatory conditions;
or
2) other relevant radio standards.

Foreword
This Harmonised European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic
compatibility and Radio spectrum Matters (ERM).
The present document has been prepared under the Commission's standardisation request C(2015) 5376 final [i.18] to
provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation
of the laws of the Member States relating to the making available on the market of radio equipment and repealing
Directive 1999/5/EC [i.14].
Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with
the normative clauses of the present document given in table A.1 confers, within the limits of the scope of the present
document, a presumption of conformity with the corresponding essential requirements of that Directive and associated
EFTA regulations.
The present document is part 4 of a multi-part deliverable covering Wireless Microphones, Audio PMSE up to 3 GHz,
as identified below:
Part 1: "Class A Receivers; Harmonised Standard covering the essential requirements of article 3.2 of Directive
2014/53/EU";

Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Executive summary
With the introduction of Directive 2014/53/EU [i.14], the present multi-part deliverable has been reformatted into
multiple parts to accommodate the different types of equipment represented, i.e. different receivers for audio
Programme Making and Special Events (PMSE); and Assistive Listening Devices (ALDs). Part 4 covers Assistive
Listening Devices including personal sound amplifiers and inductive systems with digital and analogue (FM) receivers.
It is also applicable to accessories associated with ALDs. In addition, it covers ALDs with inductive receivers (T-coils).
Introduction
With the introduction of Directive 2014/53/EU [i.14], receiver parameters are now included and the removal of the
9 kHz lower limit has brought inductive loop systems and receivers into the present document. Inductive loop
transmitters are covered within ETSI EN 303 348 [i.19] along with test receivers; hearing aids containing inductive loop
receivers (often referred to as T coil) are now covered in clause 9.2 of the present document. The frequency range of the
present document has been reduced to accommodate inductive loop receivers.
The present document is a testing standard based on spectrum utilization parameters and does not include performance
characteristics that may be required by the user nor requirements for interfacing equipment.
ETSI EN 300 422 [i.2] was originated in 1991 when Assistive Listening Devices (ALD) were a very small part of the
Radio Microphone Industry; in recent years major advances in both the volume and functionality of ALDs has caused a
rethink in how to best present the testing regime in a clear and concise manner. After a number of discussions, the
present ETSI EN 300 422 family [i.2] covers audio PMSE as Parts 1 [i.20], 2 [i.21], and 3 [i.22]; and ALDs as Part 4
(the present document).
Systems including assistive listening devices (Aids for the handicapped) with digital modulations and operating in the
range 863 MHz to 865 MHz may be tested to either the present document or to ETSI EN 301 357 [i.1] with due
consideration of power and operating frequency.
Ear worn hearing assistance devices may in some cases require stereo transmission to present both left and right audio
information to the wearer. For that reason, devices that transmit information to the hearing impaired may require two
channel operation. It is expected that two or more channel devices will be tested separately when determining
bandwidth and associated measurements. Channels may involve the use of two separate frequencies or wider
bandwidth.
Additional standards or specifications may be required for equipment:
1) intended to interface to Public Networks, e.g. PSTN. This facility may be subjected to regulatory conditions;
or
2) other relevant radio standards.
