User manual ICOM IC-PCR100

[. . . ] INSTRUCTION MANUAL COMMUNICATIONS RECEIVER FOR COMPUTER iPCR100 This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. IMPORTANT READ ALL INSTRUCTIONS carefully and completely before using the receiver. OPERATING THEORY 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 IC-PCR100 receives RF energy from 0. 5 MHz* to 1300 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.
