5.5 Self-test
Self-tests shall be performed regularly to verify that the EPIRB is working
correctly. A self-test will use battery power, so please follow the
recommendations in Chapter 6 for self-test intervals.
5.5.1 Normal self-test
1 2
To start the self-test, move the switch to test position and hold until the
test indicator light is on.
During the normal self-test, short test signals on 121.5 MHz, AIS and
Cospas-Sarsat are transmitted. The test signals will not be recognized as
distress signals. While transmitting the test signals the battery and the
transmitted signals are tested.
The test indicator will give a short dark period every time a signal is
transmitted.
If the RLS protocol is enabled the blue RLS indicator light will light up for
approximately 1 second.
The top light will flash once if the self-test is successful.
If the self-test detects a fault in the EPIRB module, the test indicator light
will start blinking at the end of the test. For fault codes see the table in
section 5.5.3.
