i EXPLICIT DEFINITIONS R WARNING! NEVER connect the transceiver to an AC outlet. This may pose a fire hazard or result in an electricshock. NEVER connect the transceiver to a power source of more than 16 V DC such as a 24 V battery. This connection will ruinthe 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 bodilyinjury. 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- CAUTIONS WORD DEFINITION R WARNING 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 complete- ly before using the transceiver. SAVE THIS INSTRUCTION MANUAL — This instruction manual contains important operating instructions forthe IC-F52 1 VHF TRANSCEIVE R and IC-F62 1 UHF TRANSCEIVER . IMPORTANT IC-F510F520_F610F620.qxd 02.1.21 10:03 AM Page b (1,1) ii peratures below –22°F (–30°C) or above +140°F (+60°C) or,in 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 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 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. onlyCAUTION: Changes or modifications to this transceiver, not expressly approved by Icom Inc., could void your authority tooperate this transceiver under FCC regulations.

20020 6 SAFETY TRAINING INFORMATION Your Icom radio generates RF electromag-netic energy during transmit mode. Thisradio 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 isNOT intended for use by the “ General Population ” in an uncontrolled environment.• For compliance with FCC and Industry Canada RF Exposure Requirements, the transmitter antenna installationshall 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 outsideof a vehicle and kept at a separation distance of 63 cen-timeters or more between the transmitter antenna of thisdevice and persons during operation. 3. IC-F621: The transmitter antenna is required to be located outsideof a vehicle and kept at a separation distance of 50 cen-timeters or more between the transmitter antenna of thisdevice and persons during operation. To ensure that your exposure to RF elec-tromagnetic energy within the FCCallowable limits for occupational use,always adhere to the following guidelines: • DO NOT operate the radio without a proper antenna attached, as this may damage the radio and may also causeyou to exceed FCC RF exposure limits. A proper antenna isthe antenna supplied with this radio by the manufacturer oran antenna speci fi cally 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 tobe 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/CompatibilityDuring transmissions, your Icom radio generates RF energythat can possibly cause interference with other devices orsystems. To avoid such interference, turn off the radio inareas 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.
