3. If the EPIRB fail to end up with a continuous light, this indicates a fault in the EPIRB.
4. Release the switch and put the EPIRB back into the bracket.What the self test actu-
ally does is first to wait app. 15 seconds to allow the reference oscillator inside the
EPIRB to warm up.Then a short burst is transmitted by the 121.5 MHz transmitter,
while the output level of the transmitter is checked. Finally, a test signal is transmitted
by the 406 transmitter. During this test signal the battery voltage, output power and
frequency is checked.
While testing the 406 MHz transmitter a test message is transmitted, this test message
is coded with a special synchronisation code and will not be detected by the COSPAS/
SARSAT satellites.The purpose of this test message  is to control the actual coding of
the EPIRB.This can be done with the  JOTRON test unit TronDEC/UniDeck or an other
EPIRB checker.

The EPIRB is normally stored in its bracket.The bracket contains means to prevent acci-
dental activation of the EPIRB.The bracket should be mounted 
in a place that is easily available for periodic testing, and a place which is easily accessible
in case an emergency situation occur.
