200206SAFETY TRAINING INFORMATIONYour Icom radio generates RF electromag-netic energy during transmit mode. Thisradio is designed for and classified as“Occupational Use Only”, meaning it mustbe 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 anuncontrolled environment.• For compliance with FCC and Industry Canada RFExposure 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 antennaattached, 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 specifically authorized by the manufacturer foruse with this radio.•DO NOT transmit for more than 50% of total radio use time(“50% duty cycle”). Transmitting more than 50% of the timecan 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 thetransmitter in areas that are sensitive to electromagnetic radi-ation such as hospitals, aircraft, and blasting sites.WARNINGCAUTION
