FCC RF EXPOSURE COMPLIANCE WARNING For compliance with FCC and Industry Canada RF Exposure Requirements, the transmitter antenna installation shall comply with the following two conditions: 1. The transmitter antenna gain shall not exceed 0 dBi 2. The transmitter antenna is required to be located outside of a vehicle and kept at a separation distance of 85 centimeters or more between the transmitter antenna of this device and persons during operation.
iIMPORTANTEXPLICIT DEFINITIONSRWARNING! NEVER connect the transceiver to anAC outlet. This may pose a fire hazard or result in an electricshock.NEVER connect the transceiver to a power source of morethan 16 V DC such as a 24 V battery. This connection will ruinthe transceiver.NEVER cut the DC power cable between the DC plug andfuse holder. If an incorrect connection is made after cutting,the transceiver might be damaged.NEVER place the transceiver where normal operation ofthe vehicle may be hindered or where it could cause bodilyinjury.NEVER allow children to touch the transceiver.NEVER expose the transceiver to rain, snow or any liquids.USE supplied microphone only. Other microphones havedifferent pin assignments and may damage the transceiver.DO NOT use or place the transceiver in areas with tem-CAUTIONSWORD DEFINITIONRWARNING Personal injury, fire hazard or electric shockmay occur.CAUTION Equipment damage may occur.NOTE If disregarded, inconvenience only. No riskof personal injury, fire or electric shock.READ ALL INSTRUCTIONS carefully and com-pletely before using the transceiver.SAVE THIS INSTRUCTION MANUAL—Thisinstruction manual contains important operating instructionsfor the IC-F610 and IC-F620 UHF TRANSCEIVERS.Icom, Icom Inc. and the logo are registered trademarks ofIcom Incorporated (Japan) in the United states, the UnitedKingdom, Germany, France, Spain, Russia and/or other coun-tries.SmarTrunk II™is a Trademark of SmarTrunk Systems, Inc.
iiperatures below –30°C or above +60°C or, in areas subjectto direct sunlight, such as the dashboard.AVOID operate the transceiver without running the vehi-cle’s engine. The vehicle’s battery will quickly run out if thetransceiver is in transmission while the vehicle’s engine OFF.AVOID placing the transceiver in excessively dusty envi-ronments.AVOID placing the transceiver against walls. This willobstruct heat dissipation.AVOID the use of chemical agents such as benzine oralcohol when cleaning, as they damage the transceiver sur-faces.BE CAREFUL! The transceiver will become hot whenoperating continuously for long periods.For U.S.A. onlyCAUTION: Changes or modifications to this transceiver, not ex-pressly approved by Icom Inc., could void your authority to operatethis transceiver under FCC regulations.TABLE OF CONTENTSIMPORTANT .................................................................................... iEXPLICIT DEFINITIONS ................................................................. iCAUTIONS ....................................................................................... iTABLE OF CONTENTS .................................................................. ii1 PANEL DESCRIPTION ........................................................ 1–6■Front panel ............................................................................ 1■Function display .................................................................... 2■Programmable function keys ................................................ 32 OPERATION ...................................................................... 7–10■Turning power ON ................................................................ 7■Channel selection ................................................................. 7■Receiving and transmitting ................................................... 8DTransmitting notes .......................................................... 8DTx code channel selection .............................................. 9DTx code number selection .............................................. 9DDTMF transmission ........................................................ 93 OPTIONAL SmarTrunk II™ OPERATION ....................... 11–12■SmarTrunk II™ and conventional modes ............................ 11■SmarTrunk II™ operation .................................................... 114 CONNECTION AND MAINTENANCE ............................. 13–19■Rear panel and connection ................................................. 13■Sullpied Accessories ........................................................... 14■Mounting the transceiver ..................................................... 15DInverting the Front panel .............................................. 15DMounting the Transceiver ............................................. 16■Optional UT-96/UT-105 installation ..................................... 17■Optional UT-109/UT-110 installation ................................... 17■Optional OPC-617 installation ............................................. 18■Antenna ............................................................................... 18■Fuse replacement ............................................................... 18■Cleaning ............................................................................. 185 OPTIONS ............................................................................... 19DOC..........................................................................................2000 IC-F610EUR.qxd 01.11.28 11:37 AM Page c (1,1)
