Foreword
This European Telecommunications Standard (ETS) has been produced by the Radio Equipment and
Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI) and
has undergone the ETSI standards approvals procedure.
The standard sets out the minimum requirements for the use of radiotelex equipment aboard ships,
operating in the maritime mobile MF/HF radio service. Equipment must be capable of transmitting on one or
more of the frequency bands assigned to the service (415 kHz to 526.5 kHz, 1605 kHz to 4.0 MHz, or 1605
kHz to 28MHz).
The standard incorporates the requirements of International Maritime Organisation (IMO) Assembly
Resolutions A 569(14) and A 613(15), CCIR Recommendations 490, 491-1 and 625 and CCITT
Recommendation F.130. It includes the performance standards for Narrow-Band Direct Printing (NBDP)
equipment operating in the Global Maritime Distress and Safety System (GMDSS). Where the equipment is
provided with a digital input panel, it must comply where practicable with CCITT Recommendation
E.161/Q.11.

1 Scope
1)
This standard states the minimum requirements for radiotelex equipment for use on board ships. These
requirements include the relevant provisions of the Radio Regulations and the performance standards for
shipborne MF/HF radio installations for Narrow Band Direct Printing (NBDP) equipment operating in the
Global Maritime Distress and Safety System (GMDSS), and of the performance standards Res. A 569(14)
and Res. A 613(15) as adopted by the International Maritime Organization (IMO).
Annex VI of CEPT Recommendation T/R 34-01, CCIR Recommendation 625, 490, 491-1 and CCITT
Recommendation F 130 are regarded as a constituent part of this standard.
Maritime radiotelex equipment shall use the error-detecting and correcting system used for direct-printing
telegraphy in the maritime mobile service as described in CCIR Recommendation 625.
The equipment shall be able to operate in the Forward Error Correcting (FEC) and Automatic Repetition
reQuest (ARQ) modes in accordance with CCIR Recommendation 625.
Maritime radiotelex equipment may consist of integrated equipment or of a combination of a maritime mobile
transmitter/receiver and external NBDP equipment. Where such a combination is used the requirements for
integrated equipment shall apply to that combination.
If the equipment, or parts of it, is designed in such a manner that it can also be used for other categories of
maritime radio communication (e.g. radiotelephony), the relevant parts of the equipment shall furthermore
fulfil the requirements of the relevant standards applicable for the service(s) in question.
2 General requirements
2.1 Construction
In all respects the mechanical and electrical design and construction and also the finish of the equipment
shall conform with good engineering practice, and the equipment shall be suitable for use on board ships at
sea.
The number of operational controls, their design and manner of function, location, arrangement and size
should provide for simple, quick and effective operation. The controls should be arranged in a manner as to
minimize the chance of inadvertent operation.
Their number should be the minimum necessary for satisfactory operation.
All operational controls should permit normal adjustments to be easily performed and should be easy to
identify from the position at which the equipment is normally operated. Controls not required for normal
operation should not be readily accessible.
The equipment should be so designed that the main units can be replaced readily, without elaborate
recalibration or readjustment.
All controls, indicators, and terminals, shall be clearly labelled. A label showing the type designation under
which the equipment is submitted for type testing, shall be fitted to the equipment so as to be clearly visible in
the normal operating position.
The serial number shall be permanently marked on each unit of the equipment or on a name plate
permanently fastened to that unit.
If the equipment consists of more than one unit, each unit shall have a clear identity.
Details of the power supply from which the equipment is intended to operate, shall also be clearly indicated.

1)
For the purposes of this standard, radiotelex equipment is defined as direct-printing telegraph equipment employing automatic
identification and error correction in the maritime mobile MF/HF radio service.

Page 12
ETS 300 067: November 1990
Equipment intended to be installed on the bridge shall be provided with adequate illumination to enable
identification of controls and facilitate reading of indicators at all times. Means shall be provided for dimming
to extinct the output of any equipment light source.
The design of the equipment shall be such that misuse of the controls shall not cause damage to the
equipment or injury to personnel.
If an equipment is connected to one or more other equipments, the performance of each shall be maintained.
Where a digital input panel with the digits "0" to "9" is provided, the digits shall, where practicable, be
arranged to conform with CCITT Recommendation E 161/Q.11.
For the purpose of maintenance, components shall be easily identifiable either by markings within the
equipment, or with the aid of the technical description.
For type-testing purposes, a comprehensive technical description shall be provided with the equipment.
Where external terminals can be used to operate the radiotelex equipment, the equipment shall be provided
with at least a standard interface in conformity with CCITT Recommendation V.10 or Recommendation
V.28 and/or be capable to operate a teleprinter in a 60 V/30 mA loop.
Where more than one keyboard/printer combination can be used, one shall have priority over the others.
At each operating position, an indication shall be available to indicate that another operating position is in
use.
Incoming calls shall have priority over the local use of the teleprinter and/or display unit.

Foreword
This European Telecommunications Standard (ETS) has been produced by the Radio Equipment and
Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI) and
has undergone the ETSI standards approvals procedure.
The standard sets out the minimum requirements for the use of radiotelex equipment aboard ships,
operating in the maritime mobile MF/HF radio service. Equipment must be capable of transmitting on one or
more of the frequency bands assigned to the service (415 kHz to 526.5 kHz, 1605 kHz to 4.0 MHz, or 1605
kHz to 28MHz).
The standard incorporates the requirements of International Maritime Organisation (IMO) Assembly
Resolutions A 569(14) and A 613(15), CCIR Recommendations 490, 491-1 and 625 and CCITT
Recommendation F.130. It includes the performance standards for Narrow-Band Direct Printing (NBDP)
equipment operating in the Global Maritime Distress and Safety System (GMDSS). Where the equipment is
provided with a digital input panel, it must comply where practicable with CCITT Recommendation
E.161/Q.11.

1 Scope
1)
This standard states the minimum requirements for radiotelex equipment for use on board ships. These
requirements include the relevant provisions of the Radio Regulations and the performance standards for
shipborne MF/HF radio installations for Narrow Band Direct Printing (NBDP) equipment operating in the
Global Maritime Distress and Safety System (GMDSS), and of the performance standards Res. A 569(14)
and Res. A 613(15) as adopted by the International Maritime Organization (IMO).
Annex VI of CEPT Recommendation T/R 34-01, CCIR Recommendation 625, 490, 491-1 and CCITT
Recommendation F 130 are regarded as a constituent part of this standard.
Maritime radiotelex equipment shall use the error-detecting and correcting system used for direct-printing
telegraphy in the maritime mobile service as described in CCIR Recommendation 625.
The equipment shall be able to operate in the Forward Error Correcting (FEC) and Automatic Repetition
reQuest (ARQ) modes in accordance with CCIR Recommendation 625.
Maritime radiotelex equipment may consist of integrated equipment or of a combination of a maritime mobile
transmitter/receiver and external NBDP equipment. Where such a combination is used the requirements for
integrated equipment shall apply to that combination.
If the equipment, or parts of it, is designed in such a manner that it can also be used for other categories of
maritime radio communication (e.g. radiotelephony), the relevant parts of the equipment shall furthermore
fulfil the requirements of the relevant standards applicable for the service(s) in question.
2 General requirements
2.1 Construction
In all respects the mechanical and electrical design and construction and also the finish of the equipment
shall conform with good engineering practice, and the equipment shall be suitable for use on board ships at
sea.
The number of operational controls, their design and manner of function, location, arrangement and size
should provide for simple, quick and effective operation. The controls should be arranged in a manner as to
minimize the chance of inadvertent operation.
Their number should be the minimum necessary for satisfactory operation.
All operational controls should permit normal adjustments to be easily performed and should be easy to
identify from the position at which the equipment is normally operated. Controls not required for normal
operation should not be readily accessible.
The equipment should be so designed that the main units can be replaced readily, without elaborate
recalibration or readjustment.
All controls, indicators, and terminals, shall be clearly labelled. A label showing the type designation under
which the equipment is submitted for type testing, shall be fitted to the equipment so as to be clearly visible in
the normal operating position.
The serial number shall be permanently marked on each unit of the equipment or on a name plate
permanently fastened to that unit.
If the equipment consists of more than one unit, each unit shall have a clear identity.
Details of the power supply from which the equipment is intended to operate, shall also be clearly indicated.

1)
For the purposes of this standard, radiotelex equipment is defined as direct-printing telegraph equipment employing automatic
identification and error correction in the maritime mobile MF/HF radio service.

Equipment intended to be installed on the bridge shall be provided with adequate illumination to enable
identification of controls and facilitate reading of indicators at all times. Means shall be provided for dimming
to extinct the output of any equipment light source.
The design of the equipment shall be such that misuse of the controls shall not cause damage to the
equipment or injury to personnel.
If an equipment is connected to one or more other equipments, the performance of each shall be maintained.
Where a digital input panel with the digits "0" to "9" is provided, the digits shall, where practicable, be
arranged to conform with CCITT Recommendation E 161/Q.11.
For the purpose of maintenance, components shall be easily identifiable either by markings within the
equipment, or with the aid of the technical description.
For type-testing purposes, a comprehensive technical description shall be provided with the equipment.
Where external terminals can be used to operate the radiotelex equipment, the equipment shall be provided
with at least a standard interface in conformity with CCITT Recommendation V.10 or Recommendation
V.28 and/or be capable to operate a teleprinter in a 60 V/30 mA loop.
Where more than one keyboard/printer combination can be used, one shall have priority over the others.
At each operating position, an indication shall be available to indicate that another operating position is in
use.
Incoming calls shall have priority over the local use of the teleprinter and/or display unit.
