INSTRUCTION MANUAL VHF MARINE TRANSCEIVER iM602 This device complies with Part 15 of the FCC rules. Operation is sub- ject 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.
We want to take a couple of moments of your time to structions for the IC-M602. thank you for making the IC-M602 your radio of choice, and hope you agree with Icom’s philosophy of “tech- nology first.” Many hours of research and development went into the design of your IC-M602.
IN CASE OF EMERGENCY NOTE If your vessel requires assistance, contact other vessels and A WARNING STICKER is supplied with the transceiver. the Coast Guard by sending a distress call on Ch 16. To comply with FCC regulations, this sticker must be affixed in such a location as to be readily seen from the operating con- USING CHANNEL 16 trols of the radio as in the diagram below.
