iiUSE the supplied microphone only. Other microphoneshave different pin assignments and may damage the trans-ceiver.DO NOT use or place the transceiver in areas with tem-peratures below –22°F (–30°C) or above +140°F (+66°C), orin areas subject to direct sunlight, such as the dashboard.AVOID operating the transceiver without running the vehi-cle’s engine. The vehicle’s battery will quickly run out if thetransceiver transmits 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 or alco-hol when cleaning, as they damage the transceiver surfaces.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 ................................................................. iPRECAUTION .................................................................................. 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 ............................................................... 9DScrambler function ................................................................ 9DUser set mode ..................................................................... 103 OPTIONAL SmarTrunk IITM OPERATION .......................... 11–12■SmarTrunk IITM and conventional modes ............................... 11■SmarTrunk IITM operation ....................................................... 114 CONNECTION AND MAINTENANCE ................................ 13–17■Rear panel and connection .................................................... 13■Supplied Accessories ............................................................. 14■Mounting the transceiver......................................................... 15■Optional UT-105, UT-108 or UT-111 installation ..................... 15■Optional UT-109 or UT-110 installation .................................. 16■Optional OPC-617 installation................................................. 16■Antenna................................................................................... 17■Fuse replacement .................................................................. 17■Cleaning ................................................................................. 175 OPTIONS ................................................................................... 186 SAFETY TRAINING INFORMATION ........................................ 19!IC-F111_F121_F211_F221.qxd 03.2.12 10:02 AM Page ii (1,1)

196SAFETY TRAINING INFORMATIONYour Icom radio generates RF electromagneticenergy during transmit mode. This radio isdesigned for and classified as “OccupationalUse Only”, meaning it must be used only duringthe course of employment by individuals awareof the hazards, and the ways to minimize suchhazards. This radio is NOT intended for use by the “GeneralPopulation” in an uncontrolled environment.• For compliance with FCC and Industry Canada RF ExposureRequirements, the transmitter antenna installation shall comply withthe following two conditions:1. The transmitter antenna gain shall not exceed 0 dBi.2. IC-F121:The antenna is required to be located outside of a vehicle andkept at a distance of 1 meter or more between the transmittingantenna of this device and any persons during operation. Forsmall vehicle as worst case, the antenna shall be located on theroof top at any place on the centre line along the vehicle in orderto achieve 1 meter separation distance. In order to ensure thisdistance is met, the installation of the antenna must be mountedat least 1 meter away from the nearest edge of the vehicle inorder to protect against exposure to bystanders.3. IC-F221:The antenna is required to be located outside of a vehicle andkept at a distance of 79 centimeters or more between the trans-mitting antenna of this device and any persons during operation.For small vehicle as worst case, the antenna shall be located onthe roof top at any place on the centre line along the vehicle inorder to achieve 79 centimeters separation distance. In order toensure this distance is met, the installation of the antenna mustbe mounted at least 79 centimeters away from the nearest edgeof the vehicle in order to protect against exposure to bystanders.To ensure that your exposure to RF electromag-netic energy is within the FCC allowable limitsfor occupational use, always adhere to the fol-lowing guidelines:•DO NOT operate the radio without a proper antenna attached, asthis may damage the radio and may also cause you to exceed FCCRF exposure limits. A proper antenna is the antenna supplied withthis radio by the manufacturer or an antenna speciﬁcally authorizedby the manufacturer for use with this radio.•DO NOT transmit for more than 50% of total radio use time (“50%duty cycle”). Transmitting more than 50% of the time can cause FCCRF exposure compliance requirements to be exceeded. The radiois transmitting when the “TX indicator” lights red. You can cause theradio to transmit by pressing the “PTT” switch.Electromagnetic Interference/CompatibilityDuring transmissions, your Icom radio generates RF energy that canpossibly cause interference with other devices or systems. To avoidsuch interference, turn off the radio in areas where signs are postedto do so. DO NOT operate the transmitter in areas that are sensitiveto electromagnetic radiation such as hospitals, aircraft, and blastingsites.WARNINGCAUTION!IC-F111_F121_F211_F221.qxd 03.2.12 10:02 AM Page 19 (1,1)
