INSTRUCTION MANUAL COMMUNICATIONS RECEIVER iR20 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. WARNING: MODIFICATION OF THIS DEVICE TO RECEIVE CELLULAR RADIO TELEPHONE SERVICE SIGNALS IS PROHIBITED UNDER FCC RULES AND FEDERAL LAW. FOREWORD Thank you for purchasing this Icom product. The IC-R20 COMMUNICATIONS RECEIVER is designed and built with Icom's superior technology and craftsmanship. With proper care, this product should provide you with years of trouble-free operation. We want to take a couple of moments of your time to thank you for making your IC-R20 your radio of choice, and hope you agree with Icom's philosophy of "technology first." Many hours of research and development went into the design of your IC-R20. IMPORTANT READ ALL INSTRUCTIONS carefully and completely before using the receiver. SAVE THIS INSTRUCTION MANUAL-- This instruction manual contains important operating instructions for the IC-R20. EXPLICIT DEFINITIONS DEFINITION Personal injury, fire hazard or electric shock R WARNING! may occur. CAUTION NOTE Equipment damage may occur. Recommended for optimum use. No risk of personal injury, fire or electric shock. WORD D FEATURES Covers 0.150­3304.999 MHz* wide frequency range *Some frequency bands are inhibited according to version External power supply operation 1250 memory channels* with 26 banks available *200 auto write and 50 scan edge channels are included. Built-in bar-antenna Dualwatch operation i Versions of the IC-R20 which display the "CE" symbol on the serial number seal, comply with the essential requirements of the European Radio and Telecommunication Terminal Directive 1999/5/EC, and that any applicable Essential Test Suite measurements have been performed. Icom, Icom Inc. and the logo are registered trademarks of Icom Incorporated (Japan) in the United States, the United Kingdom, Germany, France, Spain, Russia and/or other countries. PRECAUTION RWARNING! NEVER operate the receiver with an earphone, headphones 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. NEVER expose the receiver to rain, snow or any liquids. The receiver may be damaged. NEVER operate or touch the receiver with wet hands. This may result in an electric shock or damage the receiver. RWARNING! NEVER connect the receiver directly to an AC outlet. This may pose a fire hazard or result in an electric shock. NEVER solder the battery cell. This may damage the battery. AVOID using or placing the receiver in direct sunlight or in areas with temperatures below ­10°C (+14°F) or above +60°C (+140°F). RWARNING! NEVER operate the receiver while driving a vehicle. Safety driving requires your full attention--anything less may result in an accident. RWARNING! NEVER throw a battery cell or battery pack into a fire since as internal battery gas can cause an explosion. AVOID the use of chemical agents such as benzine or alcohol in cleaning, as they can damage the receiver's surfaces. Even when the receiver power is OFF, a slight current still flows in the circuits. Remove the battery pack or batteries from the receiver while not using it for a long time. Otherwise, the installed battery pack or batteries will become exhausted, and will need to be recharged. RWARNING! NEVER disassemble the battery pack. If the battery cell's internal material (electrolyte liquid) gets into your eyes, wash your eyes with water and obtain treatment from an eye doctor immediately. NEVER connect the receiver directly to a power source of more than 6 V DC. This will damage the receiver. RESPECT other people's privacy. Information overheard but not intended for you cannot lawfully be used in any way. For U.S.A. only NEVER connect the receiver to a power source using reverse polarity. This will damage the receiver. CAUTION: Changes or modifications to this device, not expressly approved by Icom Inc., could void your authority to operate this device under FCC regulations. ii SUPPLIED ACCESSORIES q w e r 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 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. t y OPERATING NOTES The IC-R20 may receive its own oscillated frequency, resulting in no reception or only noise reception, on some frequencies. q Antenna ...............................................................1 w Belt clip (MB-98) ................................................1 set e Battery spacer ......................................................1 r Hand strap .........................................................1 t Battery pack* (BP-206) ..........................................1 yAC adaptor*(BC-149A/D) .......................................1 (The shape of the BC-149A and BC-149D are different.) *Not supplied with some versions. The IC-R20 may receive interference from extremely strong signals on different frequencies or when using an external high-gain antenna. iii TABLE OF CONTENTS FOREWORD ................................................... i IMPORTANT ................................................... i EXPLICIT DEFINITIONS ................................ i PRECAUTION ................................................ ii SUPPLIED ACCESSORIES .......................... iii OPERATING THEORY .................................. iii OPERATING NOTES .................................... iii TABLE OF CONTENTS ................................ iv QUICK REFERENCE GUIDE .................

III QUICK REFERENCE GUIDE D Charging the battery IC-R20 Optional CP-18A/E Cigarette lighter cable with DC-DC converter to cigarette lighter socket to [DC] jack Now that you have your IC-R20 ready, you are probably excited to start listening. We would like to take you through a few basic operation steps to make your first "Scanning Experience" enjoyable. D About default setting The frequency control ([R-DIAL]) function can be traded with YZ volume control ([L-DIAL] and [Y]/[Z] keys) function by pushing for 1 sec. [1 DIAL.SEL]. However, in this QUICK REFERENCE GUIDE, the factory default setting ([R-DIAL] sets operating frequency) is used for simple instruction. AC adaptor Turn power BC-149A/D OFF. to AC outlet Charging periods: 8 hours (w/BP-206) q Install the battery pack (BP-206). w Plug the AC adaptor into an AC outlet. eTurn OFF the receiver, then insert the adaptor plug into the [DC] jack of the receiver. RWARNING!: NEVER attempt to charge any other batteries. Because the IC-R20 can charge the BP-206 only. Keep the jack cover attached when jack is not in use to protect the connectors from dust and moisture.
