Testing Your Beacon
GPS Self-Test (GNSS Self-Test)
The GPS receiver is located under the bottom front portion of the case
(indicated by “GPS Give
Clear View to Sky”)
. It is imperative that the receiver is not obstructed during the GPS self-test
or during activation to ensure that the GPS receiver is acquiring your latitude (LAT) and
longitude (LON) position. This test must be performed outside with a clear view of the sky.
This beacon has enough excess battery life to perform 20 GPS self-tests over the 5 year life of
the battery. Once this GPS testing feature reaches 20 tests, the feature will be disabled by
internal software.
To perform a GPS self-test:
1.
Unclip the antenna latch from the case and rotate antenna 90 degrees into the upright
position. (ON/OFF button will be exposed on face of beacon once antenna is in upright
position).
2.
Depress the “Test” button
between 5 and 10 seconds.
The GPS self-test light sequence is as follows: A
blue
LED will flash followed by 3 quick
blue
LED
flashes indicating that the GPS self-test has begun. Subsequent
red
LED flashes will occur
approximately every 5 seconds until GPS has been acquired by the beacon. Once valid GPS data
has been obtained, a long
green
LED flash and a strobe flash will occur, indicating a successful
GPS self-test. As long as the beacon is unable to acquire GPS coordinates, the beacon will
continue flashing the
red
LED
for no longer than 110 seconds and then terminate GPS self-test,
indicating a failed GPS self-test.
In case of a failed GPS self-test, repeat GPS self-test and if
failure persists, return the beacon to ACR Electronics, Inc. for service. The PLB-410 and PLB-435
will both display the same LED sequences but the PLB-435 will also display the following 3 things
on the screen to show a passed GPS Test: GPS Coordinates, “GNSS Test Pass,” and the total
number of GPS tests remaining that the beacon is able to run. In the event of a failed GPS Test,
the PLB-
435 will display the following on the screen: “GNSS Test Fail” followed by the total
number of GPS tests remaining that the beacon is able to run.
The maximum number of GPS tests allowed is 20. If the user tries to perform another GPS test
after the maximum of 20 has been reached, there will be a
green
LED flash, followed by 3 quick
green
LED flashes, followed by 3
red
LED flashes and the beacon will then turn off (in addition to
the 3
red
LED flashes, the PLB-435 will display a message on the screen indicating that the GPS
Test Limit has been reached). Additionally, if the total ON time of the beacon exceeds 2 hours,
the beacon will not allow any more GPS tests to run.
