This is the minimum safe separation distance estimated to meet all RF exposure compliance requirements. This 5 meter distance is based on the FCC Safe Maximum Permissible Exposure (MPE) distance of 3 meters 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. iii FAILURE TO OBSERVE THESE LIMITS MAY ALLOW THOSE WITHIN THE MPE RADIUS TO EXPERIENCE RF RADIATION ABSORPTION WHICH EXCEEDS THE FCC MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMIT. 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. !IC-M302_draft.qxd 03.9.1 6:02 PM Page iv (1,1) New2001 TABLE OF CONTENTS FOREWORD ………………………… i IMPORTANT ………………………… i EXPLICIT DEFINITIONS …………… i IN CASE OF EMERGENCY ……… ii NOTE ………………………………… ii RADIO OPERATOR WARNING … iii TABLE OF CONTENTS …………… iv PRECAUTION ……………………… v 1 OPERATING RULES…………… 1 2 PANEL DESCRIPTION ……… 2–4 ■ Panel description …………… 2 ■ Function display ……………… 3 ■ Microphone …………………… 4 3 BASIC OPERATION ………… 5–8 ■ Channel selection …………… 5 ■ Receiving and transmitting … 7 ■ Call channel programming … 8 ■ Channel names ……………… 8 ■ Microphone lock function …… 8 4 DUALWATCH/TRI-WATCH …… 9 ■ Description …………………… 9 ■ Operation ……………………… 9 5 SCAN OPERATION ……… 10–11 ■ Scan types …………………… 10 ■ Setting tag channels………… 11 ■ Starting a scan ……………… 11 6 SET MODE ………………… 12–14 ■ SET mode programming …… 12 ■ SET mode items …………… 13 7 TROUBLESHOOTING ……… 15 8 CHANNEL LIST ……………… 16 9 SPECIFICATIONS AND OPTIONS ……………………… 17 iv !IC-M302_draft.qxd 03.9.1 6:02 PM Page v (1,1) New2001 PRECAUTION RWARNING! NEVER connect the transceiver to an AC BE CAREFUL! The transceiver rear panel will become outlet. This may pose a fire hazard or result in an electric shock. hot when operating continuously for long periods. Place the transceiver in a secure place to avoid inadvertent use by children. CAUTION: Changes or modifications to this device, not expressly approved by Icom Inc., could void your authority to operate this device under FCC regulations. NEVER connect the transceiver to a power source of more than 16 V DC or use reverse polarity. This will ruin the transceiver. NEVER cut the DC power cable between the DC plug and fuse holder. If an incorrect connection is made after cutting, the transceiver may be damaged. NEVER place the transceiver where normal operation of the vessel may be hindered or where it could cause bodily injury. KEEP the transceiver at least 3.3 ft (1 m) away from the ship’s navigation compass. DO NOT use or place the transceiver in areas with temperatures below –4°F (–20°C) or above +140°F (+60°C) or, in areas subject to direct sunlight, such as the dashboard. AVOID the use of chemical agents such as benzine or alcohol when cleaning, as they may damage the transceiver surfaces. BE CAREFUL! The transceiver and optional HM-127 employ waterproof construction, which corresponds to JIS waterproof specification, Grade 7 (1 m/30 min.). However, once the transceiver or microphone has been dropped, waterproofing cannot be guaranteed due to the fact that the case may be cracked, or the waterproof seal damaged, etc. !IC-M302_draft.qxd 03.9.1 6:02 PM Page 1 (1,1) OPERATING RULES D PRIORITIES • Read all rules and regulations pertaining to priorities and keep an up-to-date copy handy. Safety and distress calls take priority over all others. • You must monitor Channel 16 when you are not operating on another channel. • False or fraudulent distress signals are prohibited and punishable by law. D PRIVACY • Information overheard but not intended for you cannot lawfully be used in any way. (2) OPERATOR’S LICENSE A Restricted Radiotelephone Operator Permit is the license most often held by small vessel radio operators when a radio is not required for safety purposes. The Restricted Radiotelephone Operator Permit must be posted or kept with the operator. Only a licensed radio operator may operate a transceiver. However, non-licensed individuals may talk over a transceiver if a licensed operator starts, supervises, ends the call and makes the necessary log entries. Keep a copy of the current government rules and regulations handy. • Indecent or profane language is prohibited. D RADIO LICENSES (1) SHIP STATION LICENSE You must have a current radio station license before using the transceiver. It is unlawful to operate a ship station which is not licensed. Inquire through your dealer or the appropriate government agency for a Ship-Radiotelephone license application. This government-issued license states the call sign which is your craft’s identification for radio purposes. Radio license for boaters (U.S.A. only) The Telecommunications Act of 1996 permits recreational boaters to have and use a VHF marine radio, EPIRB, and marine radar without having an FCC ship station license. Boaters traveling on international voyages, having an HF single sideband radiotelephone or marine satellite terminal, or required to carry a marine radio under any other regulation must still carry an FCC ship station license. For further information, see the FCC Ship Radio Stations Fact Sheet. !IC-M302_draft.qxd 03.9.1 6:02 PM Page 2 (1,1) New2001 PANEL DESCRIPTION ■ Panel description Speaker Function display u ytr e q POWER/VOLUME CONTROL [VOL] Turns power ON and OFF and adjusts the audio level.

Normal scan searches all tag channels in the selected channel group. Priority scan searches all tag channels in sequence while monitoring Channel 16. An NOAA broadcast station transmits a weather alert tone before important weather information. When the weather alert function is turned ON, the transceiver detects the alert, then the “WX ALT” indicator blinks until the transceiver is operated. The previously selected (used) weather channel is checked any time during standby or while scanning. • “WX ALT” appears instead of “WX” indication when the function is set ON. Normal scan (default) Priority scan D Scan resume timer The scan resume timer can be selected as a pause (OFF) or timer scan (ON). When OFF is selected, the scan pauses until the signal disappears. When ON is selected, the scan pauses 5 sec. and resumes even if a signal has been received on channels except for Channel 16.
