C SECTION 1 -- INTRODUCTION 1. 1 General This manual provides installation, operation and maintenance instructions for the ACR/MINI B300TM Emergency Position Indicating Radio Beacon (EPIRB), hereinafter referred to as the Beacon. [. . . ] C Modulation Frequency Stability Operating Temperatures Activation Size Weight Attachments Downward sweeping tone between 1600 and 300 Hz at 2 to 4 sweeps per second ± 3. 5 kHz (Crystal controlled) -20°C to +55°C (-14°F to +131°F) Manual "ON-OFF" switch 127mm x 66mm x 41mm (5. 0"H x 2. 6"W x 1. 6"D) excluding antenna 215 g (7. 6 ounces) Lanyards, Hanked and Wrist SECTION 2 -- INSTALLATION 2. 1 General The ACR/MINI B300TM Beacon has been designed for multi-purpose installation for survival use, personnel, rafts, floats and survival craft. It should be carried with you or stowed where it will be readily available in an emergency. Remove top cap and PC board from bottom case being careful not to disturb any electronic components on the PC board. Remove old battery and place new battery in battery clip with groove side of battery down and flat side of battery 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. Put the battery expiration date on the flat side of the battery and on the EPIRB case with ACR part no. Grease the top cap o-ring with Dow Corning number 4 Silicone Grease, ACR Part no. 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. Battery Date Code A typical Duracell DL223A battery has a date code of 6J1313. The first alphanumeric character of the code is always a number representing the last digit of the year of manufacture. The second alphanumeric character of the code is always a letter, the position of which in the alphabet represents the number of the month of manufacture. That is: A represents January, B represents February, C represents March, etc. 5 Y1-03-0136 Rev. C 2. 2 2. 3 The next two alphanumeric characters of the code represent the day of the month of manufacture. Therefore, the date of manufacture for the date code 6J1313 is October 13, 1996. 2. 4 Battery Expiry Date The battery Expiry Date is obtained by adding the battery manufacturers rated replacement life of 10 years to the date of manufacture. For example, a date code of 6J1313 would have a Battery Expiry Date of October 13, 2006. SECTION 3 -- OPERATION 3. 1 General The EPIRB is designed to operate best when placed on a flat non-conductive surface or while over water at sea. It should be operated in an area free of obstructions, which could absorb RF energy and limit radiation patterns. [. . . ] Replace the battery immediately after extended use or emergency and always on or before the battery expiry date. Safety Precautions: Warning: To avoid possible fire, explosion, leakage or burn hazard, do not open, recharge, disassemble, heat above 71°C (160°F) or incinerate. Inspection Check The following checks should be made during the periodic servicing: 1. Check the antenna tip and telescoping sections for any signs of damage or corrosion. [. . . ]
