  • Page 1 INSTRUCTION MANUAL COMMUNICATIONS RECEIVER This device complies with Part 15 of the FCC rules. Operation is sub- ject 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.

  • Page 2: Foreword

    Equipment damage may occur. If disregarded, inconvenience only. No risk NOTE of personal injury, fire or electric shock. Versions of the IC-R2 which display “CE” on the serial number seal, comply with the essential requirements of the 89/336/EEC directive for Electromagnetic Compatibility. CAUTIONS...

    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-R2 re- ceives RF energy from 0.495 MHz* to 1309.995 MHz and converts it into audio frequency (AF) energy which in turn ac- tuates a loudspeaker to create sound waves.

    Receive mode selection Receive modes are determined by the physical properties of the radio signals. The receiver has 3 receive modes: FM, AM and WFM modes. The mode selection is stored independently in each band and memory channels. Typically, AM mode is used for the AM broadcast stations (0.495–1.620 MHz) and air band (118–135.995 MHz), and WFM is used for FM broadcast stations (76–107.9 MHz).
