  1. Normally, the organization promulgated herein is not in operation,
    but, to test its efficiency, it is introduced at irregular intervals for trial
    purposes for one week.

During these periods, "test" messages will be issued by the Admiralty
to all British merchant ships, and by the Naval Authorities responsible for
the respective areas shown in the Schedule to British merchant ships in
those areas. Rugby will not, however, broadcast on Sundays, while
Falklands will do so only on 125 kc/s (2,400 metres).

Further, these "test" messages will not be broadcast by the 500 kc/s
(600 metres) stations shown in the Schedule, but, instead, brief "warning"
messages will be broadcast daily from all these stations (except in Area 1,
where only four stations will broadcast—viz., Malin Head, Land’s End,
North Foreland, and Cullercoats), stating that the test period is in force.
These broadcasts will take place twice daily during the single-operator
periods, and will be in the form "GBMS in force for test until..........."
No prior notice will be given of the dates of the "test" periods which will
commence with the promulgation of the first "test" message.

  1. The organization may, however, be brought into force at any time
    should occasion arise to transmit messages of special importance to British
    merchant ships.

  2. If and when such occasion arises to bring the organization into force,
    either generally or in any particular area, messages notifying its introduction
    will be issued by the Admiralty and/or by the Naval Authority responsible
    for the area or areas concerned. When such messages are necessary every
    available means of reaching merchant ships will be employed—i.e., the
    messages will be broadcast not only by Rugby and the other stations at the
    times shown in the Schedule, but also where stations included in the organization
    transmit navigational warnings, weather reports, &c., at routine periods,
    messages notifying its introduction will be broadcast during those periods.
    Such messages will bear the address "All British merchant ships" or
    "British merchant ships in ........... area," in full; the use of the call
    signs mentioned in paragraph 2 above will commence when the organization
    is brought into force.
