To ensure continued reliability, the unit should be checked for operation at least once every 90 (ninety) days,following the procedure of Section 5.2.2. Rinse the outside of the unit with fresh water frequently to remove any salt build-up on case or exposedparts.4.5 PACKAGING AND TRANSPORTATIONThe ACR/MINI B2TM contains lithium batteries (solid cathode, total 3.4 grams lithium). The original shippingcarton may be used or consult your local transportation authority with regard to applicable regulations fortransporting the EPIRB.SECTION 5 - TESTING5.1 GENERALThe following paragraphs detail the Beacon testing procedures.5.2 OPERATIONAL TESTINGThe Beacon can be tested by turning it ON. The test consists of the following steps:1. Flip the “OFF-ON” switch to “ON." Switch “OFF” when finished with test.2. Red LED indicator will illuminate continuously for 5 (five) seconds, indicating a functional battery.After the 5 (five) seconds, the LED will blink, confirming RF signal transmission. On the ACR/MINI B2TM ILS the LED will blink and an audible warble will sound, confirming RF signal transmission.NOTE: Tests of more than 5 (five) second duration must be conducted at designated times and duration unlessspecial arrangements are made with the USCG, FCC and/or local FAA authorities. Operational transmissiontesting may be executed only during the first five (5) minute period of any hour and only for three tone or oneoperational transmission (LED light flashing/audio warble) second, sweeps of the audio modulatingwhichever is longer.The ACR/MINI B2TM ILS has a speaker fed by voltage from the microprocessor and the transmitter, whichproduces the audible warble. This EPIRB will emit a distinctive warbling sound when operationally tested. Anychange in the audible warble, (a loss of sound or intermittent sound), is an indication that you should have yourbeacon serviced at an authorized service station. Conduct this test only during the first five (5) minutes of eachhour as indicated above.
