In addition, your Icom radio complies with the fol-lowing Standards and Guidelines with regard to RF energyand electromagnetic energy levels and evaluation of such lev-els for exposure to humans:• FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliancewith FCC Guidelines for Human Exposure to Radio Frequency Electro-magnetic Fields.• American National Standards Institute (C95.1-1992), IEEE Standard forSafety Levels with Respect to Human Exposure to Radio Frequency Elec-tromagnetic Fields, 3 kHz to 300 GHz.• American National Standards Institute (C95.3-1992), IEEE RecommendedPractice for the Measurement of Potentially Hazardous ElectromagneticFields– RF and Microwave.• The following accessories are authorized for use with this product. Use ofaccessories other than those specified may result in RF exposure levelsexceeding the FCC requirements for wireless RF exposure.; Belt Clip (MB-86, MB-103), Rechargeable Li-Ion Battery Pack (BP-245), Speaker-micro-phone (HM-125), Headset with headset adapter (HS-94, HS-95, HS-97with OPC-1392).To ensure that your expose to RF electromagnetic en-ergy is within the FCC allowable limits for occupationaluse, always adhere to the following guidelines:CAUTIONWARNING• DO NOT operate the radio without a proper antenna attached, as this maydamaged the radio and may to exceed FCC RF exposure limits. A properantenna is the antenna supplied with this radio by the manufacturer or anantenna specifically authorized by the manufacturer for use with this radio.• DO NOT transmit for more than 50% of total radio use time (“50% dutycycle”). Transmitting more than 50% of the time can cause FCC RF expo-sure compliance requirements to be exceeded. The radio is transmittingwhen the “TX indicator” lights. You can cause the radio to transmit bypressing the “PTT” switch.• ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the bodywhen transmitting and only use the Icom belt-clips which are listed onpage 33 when attaching the radio to your belt, etc., to ensure FCC RF ex-posure compliance requirements are not exceeded. To provide the recipi-ents of your transmission the best sound quality, hold the radio in analmost vertical position at least 5 cm (2 inches) from your mouth, the mi-crophone is located next to the speaker, so you should “talk into thespeaker”.The information listed above provides the user with the information needed tomake him or her aware of RF exposure, and what to do to assure that this radiooperates within FCC RF exposure limits.Electromagnetic Interference/CompatibilityDuring transmissions, your Icom radio generates RF energy that can possiblycause 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 operatethe transmitter in areas that are sensitive to electromagnetic radiation such ashospitals, aircraft, and blasting sites.IC-M72_0.qxd  05.11.21 18:46  Page i (1,1)
