6 MAINTENANCE AND TROUBLESHOOTING
6.1 EPIRB module / battery module
The EPIRB should be tested and batteries replaced according to
MSC circ.1039. See chapter 5.6.1.
6.2 Testing EPIRB module
6.2.1 Self-test with sea water contacts activated
To perform the self-test with seawater contacts activated, the
capsule has to be removed from the release mechanism. Authorized
personnel should annually test the seawater contacts.
WARNING
Releasing the Capsule from the bracket will interrupt all
connections between the ships S-VDR system and the FRM
inside the Capsule, and all recordings will be interrupted.
The regulations require the Capsule not to be removed for
more than 10 minutes.
Remove the capsule from the release mechanism and go to paragraph
6.2.2.
6.2.2 Self-test with sea water contacts deactivated
Turn the switch to the «TEST» position. The red indicator will start
flashing for approx. 15 sec. This is to allow the internal TCXO
(Temperature Controlled Xtal Oscillator) to be stable.
Then the output power of both transmitters are checked, the battery
voltage and the PLL of the 406 Transmitter.
A complete message on the 406 Frequency is transmitted, with
inverted frame sync.
