44、-1 V1.4.1 (2011-11) 104 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 a

45、ll 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

46、. 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

47、 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-frequen

48、cy channels with manual control (simplex). The equipment shall be of a colour which distinguishes it from the portable VHF equipment specified in EN 300 225 5. The equipment shall be able to operate on all channels defined in Radio Regulations, appendix 18 1, noting in particular footnotes m) and e)

49、. Additional VHF channels for maritime use outside those defined by appendix 18 to the Radio Regulations 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 I
