Foreword
This European Standard (Telecommunications series) has been produced by ETSI Technical Committee
Electromagnetic compatibility and Radio spectrum Matters (ERM).
This edition of the present document is the result of the incorporation of an amendment into the third edition of
ETS 300 225 (1998). This amendment has been approved via the ETSI standards One-step Approval Procedure. For
details, consult the document history on the last page.
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 [9] 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.

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 Radio Regulations
(see Radio Regulations, Appendices 18 [1] and 19 [2]) 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 and the International Maritime Organization Resolutions A.694(17) [4] and A.809(19) [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 [9]. 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.
Any parts of the equipment required to be checked during inspection or maintenance operations as laid down by the
manufacturer, shall be readily accessible. 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 II
