Antenna is spring loaded and deploys rapidly. The release trigger holds the antenna down at the beacon’s side in the stowed position. When the beacon is switched to the “ON” position the antenna will spring into an upright position. The antenna should then be extended to its full length for optimum transmission performance. The beacon should be operated in an area free of obstructions. 3.2 MANUAL ACTIVATION The beacon is manually activated. Manually activating the beacon requires movement of the “ON- OFF” switch to the "ON" position. Warning - Do not hold beacon near face or body while releasing the antenna. Antenna is spring loaded and deploys rapidly. From the “OFF” position, lift switch and move to the “ON” position. This will release the antenna from the stowed position. The beacon will begin transmitting and is confirmed by a steady red LED and followed by the audible warble and flashing red LED. Extend antenna to its full length. 3.3 DEACTIVATION The beacon should not be left in the "ON" position. Warning - Do not hold beacon near face or body while releasing the antenna. Antenna is spring loaded and deploys rapidly. To deactivate an "ON" beacon, lift the switch and move to the “OFF” position. Fold the antenna and recapture with quick release trigger. 3.4 OPERATIONAL NOTES The EPIRB is designed to float on water but will operate best when held upright out of water. An operational transmission on land should be conducted in an area free of obstructions, which could absorb RF energy and limit radiation patterns. Position the antenna straight up and extend (perpendicular to ground) and not pointing toward the receiving station. Note that the radiation field null occurs directly off the end of the antenna. Maintain a visual path where possible between the Beacon and the receiver, since beacons characteristically transmit "line of sight". The Beacon transmits on 121.5 MHz. SECTION 4 - MAINTENANCE 4.1 GENERAL The Beacon has been designed for use with a minimum of maintenance required. A checklist 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. 4.2 BATTERY CHECK AND SERVICE 1. See Section 5.2 for battery check. Replace Battery Pack immediately after extended use or emergency. 2. All routine service must be carried out at ACR or by factory authorized personnel at authorized service centers. In addition to replacing the battery, the o-rings will be replaced and the EPIRB will be hydro statically re-certified. Please call ACR for the location of your nearest authorized service center at least 30 days before expiration date. After the warranty period is over, Battery replacement may be performed in the field. Follow the directions below. 3. The MINI B300TM ILS EPIRB has a dated battery life. When purchasing a new battery, make sure the battery is fresh. The battery expiry date will be printed on the side of the battery. 4. The battery can be user replaced or returned to a BRC (Battery Replacement Center) for service. Call (800) 432-0227 for a BRC near you. To replace the battery, follow directions below. a. Remove four (4) screws holding the top cap of the Beacon to the case. Use a no. 2 Phillips screwdriver. Remove top cap and PC board from bottom case being careful not to disturb any electronic components on the PC board. b. Remove old battery and place new battery in battery clip with groove side of battery down and flat side of battery up. Caution: Make sure flat side of battery is up. Otherwise, the polarity of the battery would be reversed and damage to the battery will occur. The battery also poses a possible fire, explosion, or burn hazard when placed in the battery clip upside down. A semiconductor diode protects the electronics from damage due to battery reversal. c. Put the battery expiration date on the flat side of the battery and on the EPIRB case with ACR Part No. A1-20-0857 or equivalent permanent shield label. d. Grease the top cap o-ring with Dow Corning number 4 Silicone Grease, ACR Part No. A2- 09-0069. e. Replace the four- (4) screws holding the top cap to the bottom case of the Beacon. Make sure screws are tight but do not use excessive torque, which could strip the threads in the top cap. 5. All routine service or battery replacement must be carried out at ACR or by factory authorized personnel at authorized service centers. In addition to replacing the battery, the o-rings will be replaced and the EPIRB will be hydro statically re-certified. Please call ACR for the location of your nearest authorized service center at least 30 days before expiration date. 6. Safety Precautions: a) Warning: To avoid possible fire, explosion, leakage or burn hazard, ...
