Electromagnetic radiation which has frequencies of

20,000 Hz (20 kHz*) and above is called radio frequency (RF) energy because it is useful in radio transmissions. The ICR20 receives RF energy from 0.150 MHz* to 3304.999 MHz and converts it into audio frequency (AF) energy which in turn actuates a loudspeaker to create sound waves. AF energy is in the range of 20 to 20,000 Hz.

*kHz is an abbreviation of kilohertz or 1000 hertz, MHz is abbreviation of megahertz or 1,000,000 hertz, where hertz is a unit of frequency.
