IMPORTANT READ ALL INSTRUCTIONS carefully and complete-
ly before using the transceiver. SAVE THIS INSTRUCTION MANUAL This instruction manual contains important operating instructions for the IC-F621 UHF TRANSCEIVER. EXPLICIT DEFINITIONS TRANSCEIVER IC-F521 VHF and WORD RWARNING CAUTION NOTE DEFINITION Personal injury, re hazard or electric shock may occur. Equipment damage may occur. If disregarded, inconvenience only. No risk of personal injury, re or electric shock. i CAUTIONS RWARNING! NEVER connect the transceiver to an AC outlet. This may pose a re hazard or result in an electric shock. NEVER connect the transceiver to a power source of more than 16 V DC such as a 24 V battery. This connection 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 might be damaged. NEVER place the transceiver where normal operation of the vehicle may be hindered or where it could cause bodily injury. NEVER allow children to touch the transceiver. NEVER expose the transceiver to rain, snow or any liquids. USE supplied microphone only. Other microphones have different pin assignments and may damage the transceiver. DO NOT use or place the transceiver in areas with tem-
peratures below 22F (30C) or above +140F (+60C) or, in areas subject to direct sunlight, such as the dashboard. AVOID operating the transceiver without running the vehi-
cles engine. The vehicles battery will quickly run out if the transceiver is in transmission while the vehicles engine OFF. AVOID placing the transceiver in excessively dusty envi-
ronments. AVOID placing the transceiver against walls. This will obstruct heat dissipation. AVOID the use of chemical agents such as benzine or alcohol when cleaning, as they damage the transceiver sur-
faces. BE CAREFUL! The transceiver will become hot when operating continuously for long periods. For U.S.A. only CAUTION: Changes or modications to this transceiver, not expressly approved by Icom Inc., could void your authority to operate this transceiver under FCC regulations.

netic energy during transmit mode. This radio is designed for and classified as Occupational Use Only, meaning it must be used only during the course of employ-
ment by individuals aware of the hazards, and the ways to minimize such hazards. This radio is NOT intended for use by the General Population in an uncontrolled environment. 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. IC-F521:
The transmitter antenna is required to be located outside of a vehicle and kept at a separation distance of 63 cen-
timeters or more between the transmitter antenna of this device and persons during operation. 3. IC-F621:
The transmitter antenna is required to be located outside of a vehicle and kept at a separation distance of 50 cen-
timeters or more between the transmitter antenna of this device and persons during operation. To ensure that your exposure to RF elec-
tromagnetic energy within the FCC allowable limits for occupational use, always adhere to the following guidelines:
CAU TION DO NOT operate the radio without a proper antenna attached, as this may damage the radio and may also cause you to exceed FCC RF exposure limits. A proper antenna is the antenna supplied with this radio by the manufacturer or an antenna specically authorized by 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 FCC RF exposure compliance requirements to be exceeded. The radio is transmitting when the TX indica-
tor lights red. You can cause the radio to transmit by press-
ing the PTT switch. Electromagnetic Interference/Compatibility During transmissions, your Icom radio generates RF energy that can possibly cause interference with other devices or systems. To avoid such interference, turn off the radio in areas where signs are posted to do so. DO NOT operate the transmitter in areas that are sensitive to electromagnetic radi-
ation such as hospitals, aircraft, and blasting sites. 200 20 Count on us!
