Front panel will illuminate and noise will be heard coming from speaker. To turn unit off, push slide switch down to OFF position. 4. 2 To select a channel. 2 To select a channel: CAUTION: To assure ease of operation in an emergency, the radio will be tuned to Channel 16 immediately after it has been turned on. a) To select the next higher channel, briefly press the CHANNEL s key. c) To select other channels, press and hold either the CHANNEL s key or the CHANNEL t while observing the channel 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within the U. S. A. must be operationally tested on a periodic basis (FCC regulations, part 80, section 80. 834, until superseded by section 80. 1095).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. 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. 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. l. Press the CHANNEL t key to tune unit to any channel (except Channel 16). [. . . ] E 2. The commonly used pronunciation in English speaking countries MAYDAY pronounced phonetically as " ma - d a . " 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. [. . . ]
