INSTRUCTION MANUAL VHF MARINE TRANSCEIVER iM602 This device complies with Part 15 of the FCC rules. 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.
FOREWORD IMPORTANT Thank you for purchasing this Icom product. The ICM602 VHF MARINE TRANSCEIVER is designed and built with Icom’s state of the art technology and craftsmanship. With proper care, this product should provide you with years of trouble-free operation.
IN CASE OF EMERGENCY NOTE If your vessel requires assistance, contact other vessels and the Coast Guard by sending a distress call on Ch 16. A WARNING STICKER is supplied with the transceiver. To comply with FCC regulations, this sticker must be affixed in such a location as to be readily seen from the operating controls of the radio as in the diagram below. Make sure the chosen location is clean and dry before applying the sticker. (p. 48) USING CHANNEL 16 DISTRESS CALL PROCEDURE 1.
RADIO OPERATOR WARNING Icom requires the radio operator to meet the FCC Requirements for Radio Frequency Exposure. An omnidirectional antenna with gain not greater than 9 dBi must be mounted a minimum W ARN ING of 5 meters (measured from the lowest point of the antenna) vertically above the main deck and all possible personnel. This is the minimum safe separation distance estimated to meet all RF exposure compliance requirements.
