Foreword
This draft 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 defines the minimum technical characteristics required for portable VHF radio telephones
operating in survival craft and optionally on board ships at sea, in certain frequency bands allocated to the Maritime
Mobile Service (MMS). It also incorporates the requirements detailed in the Radio Regulations, International
Convention for the Safety of Life at Sea SOLAS 1974 as amended [4] and the relevant recommendations of the
International Maritime Organization.
Every EN prepared by ETSI is a voluntary standard. The present document contains text concerning type approval of
the 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.
Proposed national transposition dates
Date of latest announcement of this EN (doa): 3 months after ETSI publication
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 6 months after doa
Date of withdrawal of any conflicting National Standard (dow): 18 months after doa

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).

1 Scope
The present document states the minimum technical characteristics required for portable VHF radiotelephones operating
in the bands between 156 MHz and 174 MHz allocated to the Maritime Mobile Services by the ITU Radio Regulations
(see ITU Radio Regulations, Appendix 18 [1]) and suitable for use in survival craft and, optionally, on board ships at
sea. The requirements detailed in the Radio Regulations, International Convention for the Safety Of Life At Sea SOLAS
1974 [4] and the International Maritime Organization Resolutions A.694(17) [i.4], MSC149 (77) [i.1] and
A.809(19) [i.3] are incorporated in the present document.

4 General requirements
4.1 Construction
The equipment shall be portable and capable of being used for on-scene communications between survival craft,
between survival craft and ship and between survival craft and rescue unit. It may also be used for on-board
communications when capable of operating on appropriate frequencies.
The equipment shall comprise at least:
- an integral transmitter/receiver including antenna and battery;
- an integral control unit including a press-to-transmit switch; and
- an internal microphone and loudspeaker.
The equipment shall be of either, highly visible yellow or orange colour, or marked with a surrounding highly visible
yellow or orange marking strip, which shall be visible also during charging and storage, as applicable.
The mechanical and electrical construction and finish of the equipment shall conform in all respects to good engineering
practice and the equipment shall be suitable for use on board ships and survival craft at sea.
All controls shall be of sufficient size to enable the usual control functions to be easily performed by a user wearing
gloves for immersion suits, in accordance with SOLAS 1974 Chapter III, Regulation 32 [4]. The number of controls
should be the minimum necessary for simple and satisfactory operation. With the possible exception of channel
selection, it shall be possible to operate the equipment using only one hand.

It may also be used for on-board communications when capable of operating on appropriate frequencies. The equipment shall comprise at least: - an integral transmitter/receiver including antenna and battery; - an integral control unit including a press-to-transmit switch; and - an internal microphone and loudspeaker. The equipment shall be of either, highly visible yellow or orange colour, or marked with a surrounding highly visible yellow or orange marking strip, which shall be visible also during charging and storage, as applicable. The mechanical and electrical construction and finish of the equipment shall conform in all respects to good engineering practice and the equipment shall be suitable for use on board ships and survival craft at sea. All controls shall be of sufficient size to enable the usual control functions to be easily performed by a user wearing gloves for immersion suits, in accordance with SOLAS 1974 Chapter III, Regulation 32 [4]. The number of controls should be the minimum necessary for simple and satisfactory operation. With the possible exception of channel selection, it shall be possible to operate the equipment using only one hand. SIST EN 300 225 V1.5.1:2016

Components shall be readily identifiable. For the purpose of conformance testing in accordance with the present document, adequate technical and operational documentation shall be supplied with the equipment. The equipment shall not be unduly affected by sea water, oil, or exposure to sunlight.
The equipment shall be of small size and light weight (not more than 1,5 litres and 1,5 kg). The equipment shall have provisions for its attachment to the clothing of the user and also be provided with a wrist or neck strap. For safety reasons, the strap should include a suitable weak link to prevent the bearer from being ensnared. The manufacturer shall provide evidence on the method of attaching the equipment to the user's clothing, including the immersion suit specified in SOLAS 1974 Chapter III, Regulation 32 [4]. The manufacturer shall supply documentary proof of compliance with this requirement. 4.2 Frequencies and power The equipment shall operate only on single-frequency channels for voice communications with manual control (simplex). The equipment shall provide for transmission and reception of signals on channel 16 and at least one other single frequency channel from those specified in Appendix 18 of the Radio Regulations [1], (with the exception of the DSC calling channel 70 and AIS1 and AIS2). NOTE: Preference shall be given to simplex channels where analogue voice is the priority mode. Independent selection of transmitting and receiving frequencies shall not be possible. After switch on the equipment shall be operational within 5 seconds and meet the requirements of the present document within 1 minute. It shall not be possible to transmit during channel switching operations.
