82310_UM_ SVDR_E 33
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.
1.
Press the spring-loaded switch on top of the Capsule to the TEST
position, see paragraph 5.2. Keep hands and other objects away
from the upper part of the Capsule. (Away from the antenna).
2.
A successful test will consist of a series of blinks on the LED
test-indicator, followed by a continuous light and a strobe flash
after app.15 seconds.
3.
If the procedure fails to end up with a continuous light, this
indicates a fault in the EPIRB module. (See paragraph 6.2.1).
4.
Release the switch and put the Capsule back into the bracket.
What the self-test actually does is first to wait app.15 seconds to
allow the reference oscillator inside the EPIRB module to warm up.
Then a short burst is transmitted by the 121.5MHz 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 synchronization 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
module. This can be done with the Jotron AS test unit Tron
UNIDEC or another EPIRB tester.
