GNSS Test
!
This test should only be performed where the PLB3 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 PLB3.
Press and hold the TEST key. 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 short green
flash until either a position fix is obtained
or the GNSS test fails.
A successful test will be indicated by long red
followed by a number of green
LED flashes and
an unsuccessful 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 PLB3 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 three seconds.
For further information regarding Self Test and Self Test history use the Ocean Signal App. to connect
to your PLB3 using Near Field Communication (NFC).
