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.

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).
