User manual ACR ELECTRONICS SR-102 REV 1C

[. . . ] A photocopy of the suggested procedures for distress communications outlined in Section 5 should be kept with each radiotelephone to aid the designated operator and maximize the intelligibility and success of his radio distress request. The 16/6 Survival Craft Portable Two-Way VHF Radiotelephone is intended to be used for on-scene emergency communications between survival craft and ship, and survival craft and rescue units. The radio is equipped with a 5 year lithium survival battery pack which is user replaceable. With the lithium battery pack installed, the unit meets all IMO, SOLAS and FCC requirements for survival craft two-way VHF transceivers. [. . . ] Speak loudly and clearly into speaker area from a distance of approximately 3"--6" (7. 5 cm to 15 cm). Both Volume indicators stay lit during transmission. Keep transmissions to a minimum to conserve battery power. *NOTE: ON/OFF button is designed with a short delay to prevent accidental turn-on. BATTERY SAVE FEATURE To conserve battery life, the unit will automatically shut-off following a period of approximately 20- 30 minutes of idle radio activity. SECTION 5- SENDING DISTRESS COMMUNICATIONS The following are a set of observations intended to help the user maximize his success during the course of a rescue where two-way communication is possible. Transmit only when the channel is clear of activity, or between other stations' transmissions during a distress. Use the world recognized expression M'AIDER or MAYDAY to call for help. Note that MAYDAY is commonly pronounced as it is read in English, when utilized in English speaking countries. To improve the chances of being understood internationally, it is best to pronounce the above expression two ways: a. The internationally recognized way, M'AIDER (in French) pronounced phonetically as "m - d, " (see any French language instruction book for further details) and, b. The commonly used pronunciation in English speaking countries MAYDAY pronounced phonetically as "m - d. " To prevent the distress signal from being misunderstood, and to improve the intelligibility of the distress call, use the two pronunciations above when calling, for example (also, see example for part c): Y1-03-0079-1C 8 "M'AIDER MAYDAY M'AIDER THIS IS MARY JANE WXT599 WXT599 WXT599". Always use the ICAO Convention (Convention on International Civil Aviation) recognized alphabet for spelling. ICAO recognized alphabet: A B C D E F G H I J K L M Alpha Bravo Charlie Delta Echo Foxtrot Golf Hotel India Juliet Kilo Lima Mike N O P Q R S T U V W X Y Z November Oscar Papa Quebec Romeo Sierra Tango Uniform Victor Whiskey X-ray Yankee Zulu EXAMPLE: "M'AIDER MAYDAY M'AIDER THIS IS MARY JANE Whiskey X-ray Tango 599 Whiskey X-ray Tango 599 Whiskey X-ray Tango 599" To acknowledge that a transmission has been received and understood in its entirety, simply use the expression "R R R" spoken as "Romeo Romeo Romeo" ("R" stands for received). Note: some radio operators use the expression "Roger" instead of "Romeo". Antenna height and range of communications are intimately related. In general, a higher antenna will have a longer range than a similar lower antenna. The typical range for a transmitting radio held at about 1. 2 meters (4. 0 ft) above average water level is expected to equal 4. 5 kilometers (2. 8 statute miles). The receiving shipborne antenna can extend the range if it is mounted high. Airborne receivers greatly extend the above range (over 150 kilometers/100 miles for aircraft flying over 1500 meters/5000 ft). Because of the above fact, and to maximize the range of the survival craft VHF radiotelephone, the unit should be held as high as possible without endangering the safety of the operator. Y1-03-0079-1C 9 SECTION 6 ­ MAINTAINING THE SR-102 SURVIVAL RADIO MANDATORY TESTING Radiotelephones operated within the U. S. A. must be operationally tested on a periodic basis (FCC regulations, Part 80, section 80. 834, until superseded by section 80. 1095). To test the radiotelephone, follow the steps given below. [. . . ] *Five years for the following products: EPIRB, PLB, S-VDR, SSAS. USEFUL LIFE POLICY The typical service life of a properly maintained Product is limited to 12 years from date of manufacture. Products that are 12 years and 1 month or older from date of manufacture will not be serviced by ACR or our Battery Replacement Centers. A Product that is 12 or less years old from date of manufacture will be serviced as long as the unit appears fit to be placed back into its final operational cycle. Service includes the replacement of those items that must be replaced at service intervals and the verification that the device appears to be in good mechanical and electrical working condition by an ACR authorized service technician. NOTICES ACR Electronics diligently works to provide a high quality Product Support Manual, however, despite best efforts, information is subject to change without notice, and omissions and inaccuracies are possible.
