Release the key when the desired channel appears on the display. d) Certain channels used internationally for duplex operation, have been designated in the United States by the FCC with an "A" suffix as simplex channels. The GMDSS Survival Radio uses simplex (single-frequency) operation only. E The Survival Radio and its protective cover shall be packed with the ship's survival craft or in a survival suit. When not packed with a life raft, the radiotelephone should be stored in an accessible place, as close to the survival craft as possible. 5. 2 5. 2. 1 MANDATORY TESTING . 2 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within the U. S. A. must be operationally tested on a periodic basis (FCC regulations, part 80, section 80. 834, until superseded by section 80. 1095).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 (Note: this test requires that a separate VHF marine radio transceiver be used to monitor transmitted and received signals). Any transmissions effected for the purpose of testing the Survival Radio shall be as brief as possible. The recommended test message format is as follows: "<name of station receiving the test message> THIS IS <name of station transmitting this text><station callsign or call letters>. " EXAMPLE: "BLUE DUCK THIS IS MARY JANE WXT599. " When a second radiotelephone or the ship's receiver is utilized to monitor proper operation of the Survival Radio, the test distance between devices should be kept to a maximum and the following message format should be observed: "<name of station transmitting this text> THIS IS <name of station transmitting this text> MOBILE 1. " EXAMPLE: "MARY JANE THIS IS MARY JANE MOBILE 1 WXT599" (NOTE: if the unit to be tested is not on board the vessel containing the fixed station, "UNIT 1" should be used rather than "MOBILE 1". ) a. Remove the radio from its survival craft package. Slide ON/OFF switch up to "ON" position. Listen for the tone and for the squelch action 3 seconds after activating the unit. The receiver tunes to Channel 16 automatically when unit is turned ON. Listen for any activity on the frequency (Channel 16). If no activity is detected, transmit the test message and have someone monitor the transmission (see above for suggested test message formats). If the test signal was not heard (full quieting), replace the battery and retest. If the test signal is still not heard (full quieting), have the unit inspected at your nearest authorized service center. Have someone return the call from the monitoring station (lowest power setting) to verify proper radiotelephone receiver operation. If a response is not heard (full quieting), have the radio unit inspected at your nearest authorized service center. Y1-03-0128 Rev. [. . . ] " 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): "M'AIDER MAYDAY M'AIDER THIS IS MARY JANE WXT599 WXT599 WXT599. " c. 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 Xray 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. " d. Antenna height and range of communications are intimately related. [. . . ]
