1、INSTRUCTION MANUAL 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. iR2

2、 COMMUNICATIONS RECEIVER Downloaded by? Amateur Radio Directory? ? www.hamdirectory.info i FOREWORD READ ALL INSTRUCTIONScarefully and completely before using the receiver. SAVE THIS INSTRUCTION MANUAL This in- struction manual contains important operating instructions for the IC-R2. EXPLICIT DEFINI

3、TIONS The explicit defi nitions below apply to this instruction manual. CAUTIONS RWARNING! NEVERoperate the receiver with a head- set or other audio accessories at high volume levels. Hearing experts advise against continuous high volume operation. If you experience a ringing in your ears, reduce th

4、e volume level or discontinue use. AVOID using or placing the receiver in direct sunlight or in areas with temperatures below 10C (+14F) or above +60C (+140F). Even when the receiver power is OFF, a slight current still fl ows in the circuits.Remove batteries from the receiver when not using it for

5、a long time. Otherwise, the installed batteries will become exhausted. For U.S.A. only CAUTION: Changes or modifi cations to this device, not ex- pressly approved by Icom Inc., could void your authority to operate this device under FCC regulations. WORD R WARNING CAUTION NOTE DEFINITION Personal inj

6、ury, fire hazard or electric shock may occur. If disregarded, inconvenience only. No risk of personal injury, fire or electric shock. Equipment damage may occur. 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

7、 Electromagnetic Compatibility. ii SUPPLIED ACCESSORIES Accessories included with the receiver:Qty. q Antenna (FA-S270C) . 1 w Handstrap . 1 e Belt clip . 1 r Ni-Cd charger (BC-127A/D) and 2 Ni-Cd batteries .1 set* *Not supplied with some versions. OPERATING THEORY Electromagnetic radiation which ha

8、s 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 wav

9、es. AF energy is in the range of 20 to 20,000 Hz. *kHz is an abbreviation of kilohertz or 1000 hertz, MHz is abbrevia- tion of megahertz or 1,000,000 hertz, where hertz is a unit of fre- quency. OPERATING NOTES The IC-R2 may receive its own oscillated frequency, resulting in no reception or only noi

10、se reception, on some frequencies. The IC-R2 may receive interference from extremely strong signals on different frequencies or when using an external high-gain antenna. qwe r FOREWORD . i EXPLICIT DEFINITIONS . i CAUTIONS . i SUPPLIED ACCESSORIES . ii OPERATING THEORY . ii OPERATING NOTES . ii TABL

16、CATIONS AND OPTIONS . 3435 iii TABLE OF CONTENTS 1 1ACCESSORY ATTACHMENT DAntenna Insert the supplied antenna into the an- tenna connector and screw down the an- tenna as shown at right. Keep the jack cover attached when jack is not in use to avoid bad contacts from dust and moisture. Commercially a

17、vailable antennas may increase receiver per- formance. An optional AD-92SMA ANTENNA CONNECTOR ADAPTERis available to connect an antenna with a BNC con- nector. DBattery installation q Remove the battery cover from the receiver. w Install 2 R6 (AA) size al- kaline, dry cell or Ni-Cd batteries. Be sur

18、e to observe the cor- rect polarity. Charge Ni-Cd batteries be- fore use. (See the separate BC-127A/D instruction sheet.) Keep battery contacts clean. Its a good idea to clean bat- tery terminals once a week. DBelt clip Conveniently attaches to your belt. Slide the belt clip into the plastic loop on

19、 the back of the receiver. DHandstrap Slide the handstrap through the loop on the side of the belt clip as illus- trated at right. Facilitates carrying.
