7.3 GNSS Test
!
This test should only be performed where the EPIRB3 has a clear and
unobstructed view of the sky. This is required to allow the GNSS receiver to
acquire a signal from sufficient satellites to allow it to determine a position.
Ensure the area marked “GNSS Antenna” is not obstructed.
It is recommended that a GNSS test is carried out at least once every six months to ensure
correct operation of the EPIRB3.
Press and hold the TEST key for 5 seconds. The LED will illuminate red to indicate
the key has been pressed, then start flashing. Shortly after, the LED will cease flashing and
become a steady red light. Release the TEST key now.
During the GNSS test the LED will repeat a long red flash followed by a short green
flash until either a position fix is obtained or the GNSS test fails.
A successful test will be indicated by a number of green LED flashes and an unsuc-
cessful test will be indicated by a number of red LED flashes. The number of flashes
indicates the number of GNSS tests remaining (e.g. 7 flashes = 7 tests remaining).
The test result flashes will be repeated after 2 seconds.
If there are 10 or more tests remaining then the LED will flash 10 times only (repeated).
The EPIRB3 has the capacity to carry out 60 GNSS tests within the lifetime of the battery.
If there are no tests remaining immediately after the current test, the LED will flash green
or red rapidly for three seconds (not repeated) depending on whether the GNSS test
was successful or not, respectively.
When there are no tests remaining, the LED will flash red rapidly for three seconds (not
repeated).
The test can be ended at any time by holding the TEST key for 1 to 2 seconds.
For further information regarding Self Test and Self Test history use the Ocean Signal App
to connect to your EPIRB3 using Near Field Communication (NFC).
