Practical training, supported by appropriate laboratory work,
should be given in:
.1 correct and efficient operation of all GMDSS subsystems and
equipment under normal propagation conditions and under
typical interference conditions;
.2 safe operation of all the GMDSS communication equipment and
ancillary devices, including safety precautions;
.3 adequate and accurate keyboard skill for the satisfactory
exchange of communications;
.4 operational techniques for:
.4.1 receiver and transmitter adjustment for the
appropriate mode of operation, including digital
selective calling and direct-printing telegraphy;
.4.2 antenna adjustment and re-alignment, as appropriate;
.4.3 use of radio life-saving appliances;
.4.4 use of emergency position-indicating radio beacons
(EPIRBs);
.5 antenna rigging, repair and maintenance, as appropriate;
.6 reading and understanding of pictorial, logic and circuit
diagrams;
.7 use and care of those tools and test instruments necessary
to carry out at-sea electronic maintenance;
.8 manual soldering and desoldering techniques, including
those involving semiconductor devices and modern circuits
and the ability to distinguish whether the circuit is
suitable to be manually soldered or desoldered;
.9 tracing and repair of faults to component level where
practicable, and to board/module level in other cases;
.10 recognition and correction of conditions contributing to
the fault occurring;
.11 maintenance procedures, both preventive and corrective for
all the GMDSS communication equipment and radionavigation
equipment;
.12 methods of alleviating electrical and electromagnetic
interference such as bonding, shielding and bypassing.
