3.
A successful test will consist of a series of flashes on the red LED test indicator, followed by
a continuous light and a Xenon strobe flash after app. 15 seconds.
This is to allow the internal OCXO (Oven Controlled Reference Oscillator) to warm up.
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.
4.
If the EPIRB fails to end up with a continuous light, this indicates a fault in the EPIRB.
See chapter 1.1.

MAINTENANCE OF JOTRON EPIRB
Every Month:
Perform EPIRB self-test. See chapter
6.2.
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 45S/SX and Bracket. The Tron 45S/SX should be easily removed and replaced in the Bracket. Make
sure that the Tron 45S/SX 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 45S/SX is
the main EPIRB on board, these rules must be followed:
Every 12th month:
If the Tron 45S/SX 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’s 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:
See chapter 6.1.
