Radio Tests Required:

Daily :

Weekly :

           o The proper operation of the DSC facilities shall be tested at least once a week by means of a test call when within communication range of a coast station fitted with DSC equipment. Where a ship has been out of communication range of a coast station fitted with DSC equipment for a period of longer than one week, a test call shall be made on the first opportunity that the ship is within communication range such as a coast station.

           o Where the reserve source of energy is not a battery (for example, a motor generator), the reserve source of energy shall be tested weekly.



Monthly :

           o Each EPIRB and satellite EPIRB shall be tested at least once a month to determine its capability to operate properly using the means provided on the device and without using the satellite system.

           o Each search and rescue radar transponder shall be checked at least once a month using the in-built test facility and checked for security and signs of damage.

           o A check shall be made at least once a month on the security and condition of all batteries providing a source of energy for any part of a radio installation. The battery connections and compartment shall also be checked.

           o A check shall be made at least once a month on the conditions of all aerials and insulators.

           o Each survival craft two-way VHF equipment shall be tested at least once a month on a frequency other than 156.8 MHz (VHF Channel 16).
