5.1 Prior to carrying out any maintenance and,
upon completion, a self-test should be performed, following the instructions
on the equipment, and the results noted.
5.2 Attention is drawn to paragraph 3 on the prevention
of false distress alerts. Avoidance of live transmissions is required
to prevent unnecessary loading of the satellite channels.
5.3 It should be verified that the self-test mode
operates properly. This check could be performed by holding the switch
in self-test mode position for 1 min after the first self-test mode
burst transmission. All transmissions should cease after releasing
the self-test mode switch. Additionally, for 406 MHz satellite EPIRBs
which received the COSPAS-SARSAT type approval after October 1998
(Type Approval Certificates 106 and higher) the number of self-test
bursts should be verified to be no more than one.
