1 Scope
The present document specifies technical characteristics and methods of measurements for equipment:
1) portable Very High Frequency (VHF) transceivers operating with 25 kHz channels;
2) portable Very High Frequency (VHF) transceivers operating with both 25 kHz and 12,5 kHz channels.
These radiotelephones are not providing maritime distress and safety communications functions (i.e. not forming part of
the Global Maritime Distress and Safety System (GMDSS)) operating in certain frequency bands allocated to the
maritime mobile service using either 25 kHz or 25 kHz and 12,5 kHz channels.
The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.2] under the
conditions identified in annex A.

4 General and operational requirements
4.1 Construction
The manufacturer shall declare that compliance to the requirements of clause 4 is achieved and shall provide relevant
documentation.
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.
All controls shall be of sufficient size to enable the usual control functions to be easily performed and the number of
controls should be the minimum necessary for simple and satisfactory operation.
All parts of the equipment to be checked during inspection or maintenance operations shall be readily accessible. The

Technical documentation shall be supplied with the equipment.
The VHF maritime mobile service uses both single-frequency and two-frequency channels. For two-frequency channels

Regulations, appendix 18 [1]).
The equipment, which can consist of more than one unit, shall be capable of operating on single frequency and
two-frequency channels with manual control (simplex).
The equipment shall be of a colour which distinguishes it from the portable VHF equipment specified in clause 4.1 of
ETSI EN 300 225 [5].
The equipment shall be able to operate on appropriate channels defined in ITU Radio Regulations, appendix 18 [1],
noting in particular footnotes m) and e).
Additional VHF channels for maritime use outside those defined by appendix 18 to the ITU Radio Regulations [1] may also
be provided where permitted by relevant administrations. These channels shall be clearly identified for use as relating to the
relevant administration(s) and accessed through a positive action(s) for enabling use of these channel(s) but means shall be
provided to block any or all of these additional channels if required by the relevant administration(s).
If 12,5 kHz channels are implemented in the equipment it shall be in accordance with Annex 4 of Recommendation
ITU-R M.1084-5 [7].
The equipment shall be so designed that use of channel 70 for purposes other than DSC is prevented (see

than AIS is prevented.
ETSI
11 ETSI EN 301 178 V2.2.1 (2017-03)
Scan or multiple watch may be provided but means shall be provided to block or unblock these functions.
If the equipment is fitted with an auxiliary antenna connector, simultaneous connection of both the auxiliary antenna
and the normal antenna shall be prevented.
It shall not be possible to transmit while any frequency synthesizer used within the transmitter is out of lock.
It shall not be possible to transmit during channel switching operations.
4.2 Controls and indicators
The equipment shall have a channel selector and shall indicate the designator, as shown in ITU Radio Regulations,

ETSI ETSI EN 301 178 V2.2.1 (2017-03) 8 1 Scope The present document specifies technical characteristics and methods of measurements for equipment: 1) portable Very High Frequency (VHF) transceivers operating with 25 kHz channels; 2) portable Very High Frequency (VHF) transceivers operating with both 25 kHz and 12,5 kHz channels. These radiotelephones are not providing maritime distress and safety communications functions (i.e. not forming part of the Global Maritime Distress and Safety System (GMDSS)) operating in certain frequency bands allocated to the maritime mobile service using either 25 kHz or 25 kHz and 12,5 kHz channels.

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. All controls shall be of sufficient size to enable the usual control functions to be easily performed and the number of controls should be the minimum necessary for simple and satisfactory operation. All parts of the equipment to be checked during inspection or maintenance operations shall be readily accessible. The components shall be readily identifiable. Technical documentation shall be supplied with the equipment. The VHF maritime mobile service uses both single-frequency and two-frequency channels. For two-frequency channels there shall be a separation of 4,6 MHz between the transmitting frequency and the receiving frequency (see Radio Regulations, appendix 18 [1]). The equipment, which can consist of more than one unit, shall be capable of operating on single frequency and two-frequency channels with manual control (simplex). The equipment shall be of a colour which distinguishes it from the portable VHF equipment specified in clause 4.1 of ETSI EN 300 225 [5]. The equipment shall be able to operate on appropriate channels defined in ITU Radio Regulations, appendix 18 [1], noting in particular footnotes m) and e). Additional VHF channels for maritime use outside those defined by appendix 18 to the ITU Radio Regulations [1] may also be provided where permitted by relevant administrations. These channels shall be clearly identified for use as relating to the relevant administration(s) and accessed through a positive action(s) for enabling use of these channel(s) but means shall be provided to block any or all of these additional channels if required by the relevant administration(s). If 12,5 kHz channels are implemented in the equipment it shall be in accordance with Annex 4 of Recommendation ITU-R M.1084-5 [7]. The equipment shall be so designed that use of channel 70 for purposes other than DSC is prevented (see Recommendations ITU-R M.493-14 [3] and M.541-10 [4]), and that use of channels AIS1 and AIS2 for purposes other than AIS is prevented.
