i7800 Instruction Manual THE TRANSCEIVER A-6328H-1EX-u Printed in Japan © 2004­2006 Icom Inc. FOREWORD Congratulations! You are the owner of the world's most advanced amateur HF/50 MHz transceiver-- IC-7800. The IC-7800 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 would like to take a few moments of your time to thank you for making the IC-7800 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-7800. D FEATURES Ultimate receiver performance: third-order intercept (IP3) of +40 dBm (HF bands only), both main and sub Independent identical receiver circuits for main and sub bands provide perfect no-compromise Dualwatch operation Built-in Baudot RTTY and PSK31 modulator/demodulator and direct PC keyboard connection capability for RTTY and PSK31 operation without a PC Upgraded real-time spectrum scope-- center frequency and fix frequency modes, plus mini-scope displays 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-7800. 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 of personal injury, fire or electric shock. TRADEMARKS 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. i PRECAUTIONS R WARNING HIGH RF VOLTAGE! NEVER attach an antenna or internal antenna connector during transmission. This may result in an electrical shock or burn. DO NOT push the PTT switch when you don't actually desire to transmit. AVOID using or storing the transceiver in areas with temperatures below ±0°C (+32°F) or above +50°C (+122°F). AVOID placing the transceiver in excessively dusty environments or in direct sunlight. AVOID placing the transceiver against walls or putting anything on top of the transceiver. This may overheat the transceiver. Always place unit in a secure place to avoid inadvertent use by children. BE CAREFUL! If you use a linear amplifier, 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 manufacturers' microphones have different pin assignments, and connection to the IC-7800 may damage the transceiver or microphone. The LCD display may have cosmetic imperfections that appear as small dark or light spots. This is not a malfunction or defect, but a normal characteristic of LCD displays. During maritime mobile operation, keep the transceiver and microphone as far away as possible from the magnetic navigation compass to prevent erroneous indications. Turn [I/O] switch (on the rear panel) OFF and/or disconnect the AC power cable from the AC outlet when you will not use the transceiver for long period of time. 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. R WARNING! NEVER operate the transceiver 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 or discontinue use. R CAUTION! NEVER change the internal settings of the transceiver. This may reduce transceiver performance and/or damage to the transceiver. In particular, incorrect settings for transmitter circuits, such as output power, idling current, etc., might damage the expensive final devices. The transceiver warranty does not cover any problems caused by unauthorized internal adjustment. R CAUTION! NEVER touch the transceiver top cover when transmitting continuously for long periods. The top cover may be hot. R CAUTION! The transceiver weighs approx. 25 kg (55 lb). Always have two people available to carry, lift or turn over the transceiver. R CAUTION! The line-voltage receptacle must be near the transceiver and must be easily accessible. Avoid extension cords. R ACHTUNG! Die Steckdose muß nabe bei diesem Gerät angebracht und zugänglich sein. R NEVER let metal, wire or other objects protrude into the transceiver or into connectors on the rear panel. This may result in an electric shock. R NEVER block any cooling vents on the top, rear or bottom of the transceiver. R NEVER expose the transceiver to rain, snow or any liquids. R NEVER install the transceiver in a place without adequate ventilation. Heat dissipation may be reduced, and the transceiver may be damaged. R NEVER operate or touch the transceiver with wet hands. This may result in an electric shock or damage to the transceiver. DO NOT use chemical agents such as benzine or alcohol when cleaning the IC-7800, as they can damage the transceiver's surfaces. ii SUPPLIED ACCESSORIES q w e r t y u i o !0 !1 !2 !3 !4 !5 q AC power cable* ....................................... 1 w Antenna jumper cables ................................. 2 e Rack mounting handles ........................... 1 pair r Screws for rack mounting handles ............ 1 set t CF (Compact Flash) memory card .................. 1 y Stands ................................................ 1 pair u Spare fuse (FGB 2 A) ................................. 1 i RCA plugs ................................................ 2 o DC power plug .......................................... 1 !0 2-conductor 1/8 plugs ................................. 3 !1 3-conductor 1/8 plugs ................................. 2 !2 3-conductor 1/4 plugs ................................. 3 !3 ACC plugs (7-pin) ....................................... 2 !4 ACC plugs (8-pin) ....................................... 2 !5 Antenna connector caps .............................. 4 *May differ from that shown according to version TABLE OF CONTENTS Section 1 PANEL DESCRIPTION I Front panel ........................................................................ 1-2 I Rear panel ........................................................................ 1-12 I LCD display ..................................................................... 1-14 I Screen menu arrangement ................................................... 1-15 INSTALLATION AND CONNECTIONS I Unpacking ........................................................................
