Paragraph 3

Motor life-boat fixed radiotelegraph installations and portable radio equipment for survival craft shall be tested at least once a month using an antenna provided with the installations or equipment. In the case of motor life-boat fixed radiotelegraph installations, the test shall, where practicable, be carried out with the life-boat floating in the sea.

Batteries providing a source of energy for any part of the radio installation shall be tested at least once a month by means of a hydrometer where practicable, or where a hydrometer cannot be used, by a suitable load test. A check shall also be made of the security of the battery and its connections and the condition of the battery and its compartment.
