6.3 MAINTENANCE OF EPIRB
Every Month: Perform EPIRB self-test. See chapter 6.3.What the self-test ac-
tually does is to send out a short test signal on 121,5 and 406,037MHz, testing
the output of the transmitter. While transmitting the test signal, the battery
voltage, output power and phase lock is tested. During the test of the 406MHz
transmitter a test message is transmitted, this test message is coded with a
special synchronization code and will not be recognized as real alert by the
COSPAS/SARSAT satellites. Carry out visual inspection for defects on both the
Tron 40S MkII and Bracket. The Tron 40S MkII should be easily removed and
replaced in the Bracket. Make sure that the Tron 40S MkII and Bracket is not
painted or otherwise covered with chemicals, oil, etc. Check the expiry date of
the EPIRB Battery and the Hydrostatic Release Mechanism. Check the presen-
ce of a firmly attached lanyard in good condition and that it is neatly stowed
and is not tied to the vessel or the mounting bracket. If the Tron 40S MkII is the
main EPIRB on board, these rules must be followed:
WARNING
The EPIRB can drop out of the FB6/FB5
bracket when releasing top cover
