this radio should provide you with years We hope you agree with Icom’s philosophy of “technology first.” Many hours of research and development design of your IC-M304. DFEATURES . Large 2-digit Channel with scrolling comment . New Force5Audio . speaker . Built-in DSC meets RTCM SC101 requirement . Submersible construction . Favorite channel function . AquaQuake water draining function Icom, Icom Inc. and the logo are registered trademarks of Icom Incor porated (Japan) in the United States, the United Kingdom, Germany, France, Spain, Russia and/or other countries. FORCE5AUDIO logo is a registered trademark of Icom Incorporated (Japan) in the United States. IMPORTANT READ ALL INSTRUCTIONS carefully and completely before using the transceiver. SAVE THIS INSTRUCTION MANUAL — This instruction manual contains important operating the IC-M304. EXPLICIT DEFINITIONS WORD DEFINITION R WARNING! Personal injury, fire hazard or electric shock may occur. CAUTION Equipment damage may occur. NOTE Recommended for optimum use. No risk of personal injury, fire or electric shock. CLEAN THE TRANSCEIVER AND MICROPHONE THOROUGHLY WITH FRESH WATER after exposure to water including salt water, otherwise, the keys and switches may become inoperable due to salt crystallization. IN CASE OF EMERGENCY If your vessel requires assistance, the Coast Guard by sending a USING CHANNEL 16 DISTRESS CALL PROCEDURE 1. “MAYDAY MAYDAY MAYDAY. ” 2. “THIS IS ...............” (name of vessel) 3. Your call sign or other indication of the vessel (AND DSC ID if you have one). 4. “LOCATED AT ...............” (your position) 5. The nature of the distress and assistance required. 6. Any other information which might facilitate the rescue. Or, transmit your distress call using digital selective calling on Channel 70. USING DIGITAL SELECTIVE CALLING (Ch 70) DISTRESS CALL PROCEDURE 1. While opening the key cover, push and hold [DISTRESS] for 5 sec. until you hear 5 short beeps change to one long beep. 2. Wait for an acknowledgment from a coast station. • Channel 16 is automatically selected. 3. Push and hold [PTT] , then transmit the appropriate information as listed above. NOTE A WARNING STICKER is supplied with the transceiver. To comply with FCC regulations, in such a location as to be readily seen of the radio as in the diagram below. Make sure the chosen location is clean and dry before applying (p. 32) EXAMPLE WARNING STICKER RADIO OPERATOR WARNING Icom requires the radio operator FCC Requirements for Radio An omnidirectional antenna with greater than 9 dBi must be mounted WARNING of 5 meters (measured from the lowest the antenna) vertically above the main deck all possible personnel. This is the minimum safe separation distance estimated to meet all RF exposure compliance This 5 meter distance is based on the FCC Safe Maximum Permissible Exposure (MPE) distance of added to the height of an adult (2 meters) and is appropriate for all vessels. For watercraft without suitable structures, the antenna must be mounted so as to maintain a minimum of 1 meter vertically between the antenna, (measured from the lowest point of the antenna), to the heads of all persons AND all persons must stay outside of the 3 meter MPE radius. Do not transmit with radio and antenna when persons are within the MPE radius of the antenna, unless such persons (such as driver or radio operator) are shielded from antenna field by a grounded metallic barrier. The MPE Radius is the minimum distance from the antenna axis that person should maintain in order to avoid RF exposure higher than the allowable MPE level set by FCC. FAILURE TO OBSERVE THESE LIMITS MAY ALLOW THOSE WITHIN THE MPE RADIUS EXPERIENCE RF RADIATION ABSORPTION WHICH EXCEEDS MAXIMUM PERMISSIBLE EXPOSURE IT IS THE RESPONSIBILITY OF THE RADIO OPERATOR TO ENSURE THAT THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS ARE OBSERVED AT ALL TIMES DURING RADIO TRANSMISSION. THE RADIO OPERATOR IS TO ENSURE THAT NO BYSTANDERS COME WITHIN THE RADIUS OF THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS. Determining MPE Radius THE MAXIMUM PERMISSIBLE EXPOSURE (MPE) RADIUS HAS BEEN ESTIMATED TO BE A RADIUS OF ABOUT 3M PER OET BULLETIN 65 OF THE FCC. THIS ESTIMATE IS MADE ASSUMING THE MAXIMUM POWER OF THE RADIO AND ANTENNAS WITH A MAXIMUM GAIN OF 9dBi ARE USED FOR A SHIP MOUNTED SYSTEM.
