Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. IMPORTANT READ ALL INSTRUCTIONS carefully and completely before using the transceiver. SAVE THIS INSTRUCTION MANUAL -- This instruction manual contains important operating instructions for the IC-M502. IN CASE OF EMERGENCY If your vessel requires assistance, contact other vessels and the Coast Guard by sending a distress call on channel 16. Or, transmit your distress call using digital selective calling on channel 70. 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 9-digit DSC ID if you have one). 4. "LOCATED AT ..............." (your position) 5. The kind of the distress and assistance required. 6. Any other information which might facilitate the rescue. i USING DIGITAL SELECTIVE CALLING (Ch 70) DISTRESS CALL PROCEDURE 1. While lifting up the switch 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 at left.

NEVER connect the transceiver to an AC outlet. This may pose a fire hazard or result in an electric shock. AVOID the use of chemical agents such as benzine or alcohol when cleaning, as they may damage the transceiver surfaces. BE CAREFUL! The transceiver rear panel will become 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 vehicle 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. 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. CLEAN THE TRANSCEIVER AND MICROPHONE THOROUGHLY WITH FRESH WATER after exposure to water including fresh water, otherwise, the keys and iii OPERATING RULES 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. 1 (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. PRIVACY · Information overheard but not intended for you cannot lawfully be used in any way. · Indecent or profane language is prohibited. 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. 1 2 PANEL DESCRIPTION I Panel description q POWER SWITCH [POWER] Push to toggle the transceiver power ON and OFF. w VOLUME CONTROL [VOL] Adjusts the audio level.
