Self Test
The Self Test verifies all key functions of the PLB including the remaining battery life
and transmitter operation.
• Press and hold the
TEST
button until the indicator
light flashes once.
• After a few seconds, there will
be a sequence of flashes.
• The PLB will switch off after
the test is completed.
GPS Signal Acquisition Test
• Start this test indoors, out of view of the open sky.
• Immediately after completing a Self Test as described
above, press and hold the
TEST button again for 30
seconds - the indicator light will start flashing slowly,
indicating that the GPS is searching for a signal.
• Move outside so that the PLB now has a clear
view of the sky.
• Ensure GPS Zone on unit is not obstructed.
• Unit will flash slowly until GPS fix is acquired.
• A series of long flashes indicates a successful
GPS fix and the number of GPS tests remaining.
• If no GPS fix is acquired after 5 minutes, the test
will fail and the indicator light will stop flashing.
• To preserve battery life, a maximum of 10 GPS
tests are permitted during each battery’s 6 year
storage life, after which further GPS tests are
prohibited until the battery is replaced.
