this radio by the manufacturer or an antenna specifically 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 indicator” lights red. You can cause the radio to transmit by pressing the “PTT” switch. • ALWAYS use Icom authorized accessories (antennas, batteries, belt clip
