Regulation 10 Additional radio equipment to be provided for area A1/A2 ships
In addition to meeting the requirements of regulation 8, every area A1/A2 ship shall be provided with—
an MF radio installation capable of transmitting and receiving, for distress and safety purposes, on the frequencies—
2,187.5 kHz using DSC; and
2,182 kHz using radiotelephony;
a radio installation capable of maintaining a continuous DSC watch on the frequency 2,187.5 kHz; such installation may be separate from, or combined with, that required by paragraph (a)(i) of this regulation; and
means of initiating the transmission of ship-to-shore distress alerts by a radio service other than MF operating either—
through the polar orbiting satellite service on 406 MHz; this requirement may be fulfilled by the satellite EPIRB, required by regulation 8(1)(f) if it is installed close to, or capable of remote activation from, the position from which the ship is normally navigated; or
on HF using DSC; or
through the INMARSAT geostationary satellite service; this requirement may be fulfilled by—
the equipment specified in paragrah (3)(b) of this regulation; or
the satellite EPIRB, required by regulation 8(1)(f) it is is installed close to, or capable of remote activation from, the position from which the ship is normally navigated.
Means shall be provided to initiate transmission of distress alerts by the radio installations specified in paragraphs (1)(a) and (1)(c) of this regulation from the position from which the ship is normally navigated.
The ship shall, in addition, be capable of transmitting and receiving general radiocommunications using radiotelephony or direct-printing telegraphy by either—
a radio installation operating on working frequencies in the bands between 1,605 kHz and 4,000 kHz or between 4,000 kHz and 27,500 kHz. This requirement may be fulfilled by the addition of this capability in the equipment required by paragraph (1)(a) of this regulation; or
an INMARSAT ship earth station.
