Daily

a) The proper functioning of the DSC facilities shall be tested at least once each day, without radiation of signals, by use of the means provided on the equipment.
b) Batteries providing a source of energy for any part of the radio installations shall be tested daily and where necessary, brought up to the fully charged condition.
c) Printers shall be checked everyday to ensure that there is an adequate supply of paper.

Weekly

a) 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. When a vessel 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 vessel is within communication range of such a coast station. If a vessel fails to receive an acknowledgement from shore, additional test calls should be made to other stations on different frequencies and records maintained. If the vessel still does not get an acknowledgement, a self test should be done, a test call should be sent to another vessel and office to be informed. At least one such test call every month should be done on 24 V / DC and logged.
b) Where the reserve source of energy is not a battery (emergency generator), the reserve source of energy shall be tested weekly.
c) Each survival craft two-way VHP equipment shall be tested at least once a month on a frequency other than 156.8 MHz (VHF Channel 16), unless the equipment is of a sealed type where such testing is not practical. The sealed batteries must not be touched. All tests should be using the test batteries.
d) NBDP self-test and test from coastal Radio station shall Test and Maintenance Routines Equipment Test and Reserve Energy Checks be carried out once a week.

Monthly

a) 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.
b) 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.
c) 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.
d) A check shall be made at least once a month on the conditions of all aerials and insulators.
e) 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).
