Basic Self Test (No Gps Data); Testing Your Beacon - ACR Electronics Cobham ResQLink PLB-375 Product Support Manual

6. Testing Your Beacon

Your beacon has the ability to perform 2 different tests to
ensure the beacon is working perfectly. The first is a basic self
test which checks the beacons Data Integrity and Memory; 406
MHz Synthesizer; RF Power/Battery; GPS header and sends a
satellite burst. The second test is a GPS Self Test that actually
turns the GPS Receiver on, downloads your position and then
transmits this data in the Self Test satellite burst.
Note: Self test should only be performed in the first 5 minutes of
any hour.

Basic Self Test (No GPS Data)

During a Self-test your beacon will send a 406 MHz signal coded
as Self-test to the satellite system and a 121.5 MHz homing
signal.
This beacon has enough excess battery life to perform 60 self
tests over the 5 year life of the battery.
To perform a Basic Self Test:
1. Unclip the antenna latch from the case.
2. Move the antenna into the upright position
3. Depress the Test button for 1 full second
A Green Light will flash followed by a Second Long Green Light
flash and the strobe light. This indicates a successful Basic Self
Test.
If a red LED flashes at the completion of the Self-test, your
beacon has failed. Repeat the Self-test. If the failure persists,
contact ACR Electronics
Center for servicing of your beacon.
or an authorized Battery Replacement
ACR strongly recommends performing the Self-Test
once per month, or at least two weeks prior to a trip
allowing enough time for service should your beacon
require it.
Battery Witness Seal Life
If your beacon flashes an initial Amber light at the
beginning of the Self- test, this indicates that your
electronic witness has been broken and you have used
more than 1 hour of battery life. While the beacon will still
operate normally in a distress situation, ACR strongly
recommends you have your battery replaced and the
electronic witness reset to ensure that you will have at
least 24 hours of battery power.
