Testing
It is important to perform regular testing of equipment to ensure proper
operation. This also ensures the EPIRB is in good working order and
therefore ready for use in a potential emergency.
9.2.1
Self-test
The purpose of a self-test is to verify that the EPIRB functions as it should.
During this test, a short test signal on 121,5MHz and 406,037MHz are sent
to test the output of the transmitter and operation of the EPIRB. While
transmitting the test signal, the battery voltage and status, output power
and phase lock are tested. When testing the 406MHz transmitter a test
message is transmitted, this test message is coded with a special
synchronization code that will not be recognized as an actual alert by the
Cospas-Sarsat satellites.
There are two types of tests:
1.
Self-test
2.
Extended self-test including GPS test
Testing should be completed within the first 5 mins of
an hour as the satellite EPIRB emits a 121,5 MHz signal
during testing.
To perform a self-test, do the following:
1.
Remove the EPIRB from the bracket.
