6 SELF-TEST
The purpose of a self-test is to verify that the beacon is working correctly. During this
test a short test signal on 121.5 MHz and 406.037 MHz is sent testing the output of
the transmitter and operation of the EPIRB. While transmitting the test signal, battery
voltage, output power and phase lock are tested. During the test of the 406MHz
transmitter a test message is transmitted, this test message is coded with a special
code and will not be recognized as real alert by the Cospas-Sarsat satellites.
Th ere are two different kinds of tests that can be performed:
1. Normal self-test.
2. Extended self-test including the GPS.
Jotron AS recommends the Tron 40VDR Float Free Capsule to be tested every
month. This test involves both the self-test and GPS-test. Note: The extended
self-test are
limited
to 60 for a period of 5-year.
WARNING: Tests must be limited to the first five minutes of the hour
(due to transmission of the 121.5 MHz.)
6.1 NORMAL SELF-TEST
To perform the normal self-test, do the following:
1. Release the front cover by removing the safety clip.
2. Take the Tron 40VDR float free capsule out
of the bracket.
3. Move the switch gently from the READY position to the
TEST position and hold for 15 sec.
4. Keep hands and other objects away from the antenna.
5. A single flash indicates passed test, others see chapter 6.3.
