INSTRUCTION MANUAL COMMUNICATIONS RECEIVER iR2 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. FOREWORD READ ALL INSTRUCTIONS carefully and completely before using the receiver. CAUTIONS R WARNING! NEVER operate the receiver with a headset 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 the volume level or discontinue use. AVOID using or placing the receiver in direct sunlight or in SAVE THIS INSTRUCTION MANUAL -- This instruction manual contains important operating instructions for the IC-R2. EXPLICIT DEFINITIONS The explicit definitions below apply to this instruction manual. WORD R WARNING CAUTION NOTE DEFINITION Personal injury, fire hazard or electric shock may occur. Equipment damage may occur. If disregarded, inconvenience only. No risk of personal injury, fire or electric shock. areas with temperatures below ­10°C (+14°F) or above +60°C (+140°F). Even when the receiver power is OFF, a slight current still flows in the circuits. Remove batteries from the receiver when not using it for a long time. Otherwise, the installed batteries will become exhausted. For U.S.A. only CAUTION: Changes or modifications to this device, not expressly approved by Icom Inc., could void your authority to operate this device under FCC regulations. 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. i 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 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 receives RF energy from 0.495 MHz* to 1309.995 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. q w e OPERATING NOTES r The IC-R2 may receive its own oscillated frequency, resulting in no reception or only noise 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. ii TABLE OF CONTENTS FOREWORD ...................................... i EXPLICIT DEFINITIONS ................... i CAUTIONS ......................................... i SUPPLIED ACCESSORIES .............. ii OPERATING THEORY ...................... ii OPERATING NOTES ........................ ii TABLE OF CONTENTS .................... iii 1 ACCESSORY ATTACHMENT ..... 1 2 PANEL DESCRIPTION .......... 2 ­ 5 s Panel description ...................... 2 s Function display ........................ 4 3 FREQUENCY AND CHANNEL SETTING ................................ 6 ­ 8 s VFO and memory channels ...... 6 s Operating band selection .......... 6 s Setting a frequency ................... 7 s Setting a tuning step ................. 7 s Selecting a memory channel .... 8 s Lock function ............................ 8 s Attenuator function ................... 8 4 BASIC OPERATION ............. 9 ­ 11 s Receiving .................................. 9 s Setting volume level ................ 10 s Setting squelch level ............... 10 iii s Monitor function ...................... 10 s Receive mode selection ......... 11 s Display backlighting ................ 11 5 MEMORY CHANNELS ....... 12 ­ 14 s General ................................... 12 s Programming during selection 12 s Programming after selection ... 13 s Transferring memory contents to another memory ................. 13 s Memory bank selection .......... 14 s Memory clear .......................... 14 6 SCAN OPERATION ............ 15 ­ 19 s Scan types .............................. 15 s Full/band/programmed scan ... 16 s Memory (bank) scan ............... 16 s Selecting scan edges ............. 17 s Skip channel setting ............... 18 s Scan resume condition ........... 18 s Frequency skip function .......... 19 7 PRIORITY WATCH ............. 20 ­ 21 s Priority watch types ................ 20 s Priority watch operation .......... 21 8 SUBAUDIBLE TONE OPERATION ....................... 22 ­ 23 s Tone squelch operation .......... 22 s Pocket beep operation ............ 23 s Tone scan ............................... 23 9 DUPLEX OPERATION .............. 24 10 OTHER FUNCTIONS ......... 25 ­ 30 s Set mode ................................ 25 s Dial select step ....................... 26 s Beep tones ............................. 26 s Power saver ............................ 26 s Auto power-off function ........... 27 s Monitor switch action .............. 27 s Dial speed acceleration .......... 28 s Lock function effect ................. 28 s Channel indication mode ........ 29 s Cloning function ...................... 29 s Partial reset ............................ 30 s All reset ................................... 30 11 TROUBLESHOOTING .............. 31 12 OPERATION FLOW CHART.. 32 ­ 33 13 SPECIFICATIONS AND OPTIONS ............................ 34 ­ 35 ACCESSORY ATTACHMENT D Antenna Insert the supplied antenna into the antenna connector and screw down the antenna as shown at right.
