6.4 MAINTENANCE OF EPIRB
Every Month: Perform EPIRB self-test.
What the self-test actually 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 40GPS MkII and
Bracket. The Tron 40GPS MkII should be easily removed and replaced in the Bracket. Make sure that the
Tron 40GPS 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 presence 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 40GPS MkII is the main EPIRB on board, these rules must be followed:
Every 12th month:
If the Tron 40GPS MkII is the main EPIRB on board and the ship falls under the SOLAS regulations of
SBM, these rules must be followed: Perform extended annual test according to IMO’s MSC/Circ.1040
(Annual testing of 406 MHz satellite EPIRBs) as required by SOLAS IV/15.9.This test can be carried out
by one of Jotron AS authorized representatives or any other service provider in possession of a Tron
UNIDEC, Tron DEC or any other Cospas/Sarsat EPIRB tester/decoder.
Every 2ndYear:
Hydrostatic Release Mechanism including Plastic Bolt on the Float Free Brackets must be replaced.
(Check expiry date on label).
Every 5thYear:
