that your EPIRB gets back to you. If someone attempts to register an EPIRB reported as stolen, your national authority will notify the appropriate police department. Visit www.cospas-sarsat.org for more detailed information.

6.Servicing the manual release bracket

To remove a beacon from the bracket, lift the latch and release the pressure from the beacon. The beacon will now be able to slide upwards out of the bracket.

It is not anticipated that the bracket will require servicing other than periodic cleaning.

Brackets are a key part of the overall beacon system. They hold a beacon ready for deployment while preventing false alarms.

NOTE: Whenever a beacon is returned for service, it must be accompanied by the bracket.

7.Self-testing the beacon

The RLB-40 beacon may be self-tested up to a maximum of sixty times in the five-year life of the battery, or once per month for the life of the battery. Self- tests can be performed randomly, however, ACR recommends that you perform the Self-test on a once per month schedule. Do not exceed the limit in order to conserve the battery for emergency use.

The functional Self-test is initiated by momentarily lifting the Activation Switch to a vertical position and holding it in this position for at least one second and at most four seconds. A beep indicates the initiation of the Self-test sequence. Self-test will check battery capacity and perform five functional tests, which include the battery life, beacon memory, board circuit, 406 RF and strobe test.

The last green LED flash and a long beep indicate a successful test. If any of the individual tests fail during Self-test, there will be two beeps and a red LED flash. Self-test will discontinue at that point.

NOTE: The “beeps” are a very high-pitched tone that some people may not be able to hear. When performing the Self-test, you may count the green LED flashes.
