User manual ACR ELECTRONICS MINI B2 CLASS B PERSONAL EPIRB

[. . . ] Do not turn it off and on in the misguided belief that you are saving battery power. Follow the instructions in section 5 to operationally test your EPIRB. Search And Rescue forces will respond to all known emergencies. This EPIRB will alert the authorities to an emergency if activated in most coastal waters, (excluding parts of Africa and Antarctica). [. . . ] TM ACR designed the MINI B2 ILS with an audible warble to help reduce the incidence of accidental activation. The audible warble also allows you to self test your beacon more effectively. NEVER operationally test your Class B EPIRB except as noted in Section 5. 2 of this manual. 1. 6 TECHNICAL DATA Pertinent technical data is listed below: ITEM Frequency Power Output Operating Life Battery Emission Modulation Frequency Stability Operating Temperatures Activation Size Weight Attachments Accessories CHARACTERISTICS 121. 5 and 243. 0 MHz (simultaneous) Minimum 75 mW on each frequency during 48 hours continuous operation 48 hours minimum at -20°, (-4°F) longer in temperate climates Lithium battery, 12 year shelf life, 6 year replacement interval (as per regulation) Type A3X Downward sweeping tone between 1600 and 300 Hz at 2 to 4 sweeps per second . 005% (Crystal controlled) -20°C to +55°C (-4°F to +131°F) Manual " ON-OFF"switch 6. 0" H x 2. 6" W x 1. 6" D (152mm x 66mm x 41mm) excluding antenna 9. 9 ounces (280 g) Lanyards, Hanked and Wrist ACR/MINI B2TM Mounting Bracket, (Optional) PN 9321 SECTION 2 - INSTALLATION 2. 1 GENERAL TM The ACR/MINI B2 Beacon has been designed for multi-purpose installation for survival use, personnel, rafts, floats and survival craft. It should be stowed where it will be readily available in an emergency, or mounted TM where easily accessible with the optional ACR/MINI B2 Mounting Bracket. SECTION 3 - OPERATION 3. 1 GENERAL TM The ACR/MINI B2 Beacon is designed to be manually deployed and activated. It may be hand held on the deck of vessels or attached with the lanyard provided to survival suits, a raft or life vest. The beacon should be in a vertical orientation, (antenna "UP"), to transmit effectively. It should be operated in an area free of obstructions. MANUAL DEPLOYMENT Remove the Beacon from its mounting or storage position and ensure that the antenna is in an upright position. Flip the switch to the "ON" position. The LED indicator will remain on for 5 seconds indicating that the batteries are functional. After 5 seconds, the LED indicator will begin flashing, indicating that the transmitter is functioning properly. 2763, will also emit an audio warble, again indicating that the transmitter is functioning properly. If operated from the deck of the vessel, choose the most advantageous position free of surrounding obstacles. If deployed in water, make sure that the antenna is positioned vertically and the antenna itself is out of the water. It is preferable to hold the unit above the water, as immersion reduces effectiveness. 3. 2 SECTION 4 - MAINTENANCE 4. 1 GENERAL The Beacon has been designed for use with a minimum of maintenance required. A check list is given in this section, and when accomplished periodically, should help to assure emergency operation and extended life use. CAUTION: Perform all maintenance operations and checks within a screen room, if available, to prevent inadvertent transmission of emergency signals. If a screen room is not available, use caution in handling the Beacon during servicing to prevent signal transmission. Replace Battery Pack immediately after extended use or emergency. The ACR/MINI B2 EPIRB has a dated battery life. The battery is dated at a six (6) year period or half the actual life of the battery, which is 12 years. Replacement must be done at six (6) years per FCC regulations. [. . . ] After the 5 (five) seconds, the LED will blink, confirming RF signal transmission. On the ACR/MINI B TM 2 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 unless special arrangements are made with the USCG, FCC and/or local FAA authorities. Operational transmission testing may be executed only during the first five (5) minute period of any hour and only for three tone or one operational transmission (LED light flashing/audio warble) second, sweeps of the audio modulating whichever is longer.
