GPS test
Warning: as testing the GPS receiver expends significant amounts of battery energy do
not test the GPS operation more than once a year. Testing the GPS receiver is limited to
12 tests over the lifetime of the battery, after this the GPS test will fail to activate.
This test must only be performed where the EPIRB has a clear and unobstructed view of
the sky. This is required to allow the GPS receiver to acquire a signal from sufficient
satellites to allow it to determine a position. Make sure the area marked “GPS antenna”
is not obstructed.
Rotate and hold the TEST key for ten seconds. The LED will illuminate red to indicate the
key has been pressed then start flashing. Release the test key between 10 and 15 seconds.
If the TEST key is released before ten seconds, the EPIRB will enter the self test
mode.
If the TEST key is inadvertently held for over 15 seconds, the LED will start flashing
green. Release the TEST key and wait for 2 minutes before attempting another GPS
test
After entering the GPS test mode the LED will change to a long red flash and a short green
flash until either a position fix is obtained or the GPS test fails. A successful test will be
indicated by the strobe flashing and the green LED flashing. The number of green flashes
indicates the number of GPS tests remaining. The unit automatically turns off after the
test indication.
If after five minutes the GPS receiver has not received a position, a failure will be indicated
by the red LED flashing after which the unit will turn off.
The test can be ended at any time by rotating the TEST key for five seconds.
