INSTRUCTION MANUAL HF/50 MHz ALL MODE TRANSCEIVER i703 FOREWORD Thank We understand that you have a choice of many different radios in the market place. We want to take a couple of moments of your time to thank you for making the IC-703 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-703. IMPORTANT READ THIS INSTRUCTION MANUAL CAREFULLY before attempting to operate the transceiver. SAVE THIS INSTRUCTION MANUAL. This manual contains important safety and operating instructions for the IC-703. FEATURES DSP features (AF DSP; UT-106 DSP UNIT required some version) All mode capability covering 160­6 m 9.0­15.87 V operation Compact with detachable front panel ±0.5 ppm of high frequency stability Built in antenna tuner Simple band scope function EXPLICIT DEFINITIONS 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 or personal injury, fire or electric shock. PRECAUTION R WARNING RF EXPOSURE! This device emits Radio Frequency (RF) energy. Extreme caution should be observed when operating this device. If you have any questions regarding RF exposure and safety standards please refer to the Federal Communications Commission Office of Engineering and Technology's report on Evaluating Compliance with FCC Guidelines for Human Radio Frequency Electromagnetic Fields (OET Bulletin 65). R WARNING HIGH VOLTAGE! NEVER attach an antenna or internal antenna connector during transmission. This may result in an electrical shock or burn. R NEVER apply AC to the [DC13.8V] receptacle on the transceiver rear panel. This could cause a fire or damage the transceiver. AVOID placing the transceiver against walls or putting anything on top of the transceiver. This will obstruct heat dissipation. Place unit in a secure place to avoid inadvertent use by children. During mobile operation, DO NOT operate the transceiver without running the vehicle's engine. When the transceiver's power is ON and your vehicle's engine is OFF, the vehicle's battery will soon become exhausted. Make sure the transceiver power is OFF before starting the vehicle. This will avoid possible damage to the transceiver by ignition voltage spikes. During maritime mobile operation, keep the transceiver and microphone as far away as possible from the magnetic navigation compass to prevent erroneous indications. BE CAREFUL! The rear panel will become hot when operating the transceiver continuously for long periods. BE CAREFUL! If a linear amplifier is connected, set the transceiver's RF output power to less than the linear amplifier's maximum input level, otherwise, the linear amplifier will be damaged. Use Icom microphones only (supplied or optional). Other manufacturer's microphones have different pin assignments, and connection to the IC-703 may damage the transceiver. R NEVER apply more than 16 V DC, such as a 24 V battery, to the [DC13.8V] receptacle on the transceiver rear panel. This could cause a fire or damage the transceiver. R NEVER let metal, wire or other objects touch any internal part or connectors on the rear panel of the transceiver. This may result in an electric shock. NEVER expose the transceiver to rain, snow or any liquids. AVOID using or placing the transceiver in areas with temperatures below ­10°C (+14°F) or above +60°C (+140°F). Be aware that temperatures on a vehicle's dashboard can exceed 80°C (+176°F), resulting in permanent damage to the transceiver if left there for extended periods. AVOID placing the transceiver in excessively dusty environments or in direct sunlight. Beat signals may be heard on some frequencies. These will occur as a result of circuit construction. For U.S.A. only Caution: Changes or modifications to this transceiver, not expressly approved by Icom Inc., could void your authority to operate this transceiver under FCC regulations. i TABLE OF CONTENTS Quick Reference 1 2 3 4 5 6 7 8 9 10 SUPPLIED ACCESSORIES The transceiver comes with the following accessories.
