INSTRUCTION MANUAL i706MKTMG HF/VHF/UHF ALL MODE TRANSCEIVER 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. IMPORTANT Read this instruction manual carefully before attempting to operate the transceiver. Save this instruction manual. This instruction manual contains important safety and operating instructions for the IC-706MKIIG. PRECAUTIONS RWARNING HIGH VOLTAGE! NEVER attach an antenna or internal antenna connector during transmission. This may result in an electrical shock or burn. During mobile operation, DO NOT operate the transceiver without running the vehicle's engine. When transceiver 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 heatsink 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-706MKIIG may damage the transceiver. 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. RNEVER apply AC to the [DC13.8V] socket on the transceiver rear panel. This could cause a fire or ruin the transceiver. RNEVER apply more than 16 V DC, such as a 24 V battery, to the [DC13.8V] socket on the transceiver rear panel. This could cause a fire or ruin the transceiver. RNEVER let metal, wire or other objects touch any internal part or connectors on the rear panel of the transceiver. This will cause electric shock. RNEVER expose the transceiver to rain, snow or any liquids. NEVER allow children to play with the transceiver. 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, resulting in permanent damage to the transceiver's front panel if left there for extended periods. 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 will obstruct heat dissipation. EXPLICIT DEFINITIONS The explicit definitions described below apply to this instruction manual. DEFINITION Personal injury, fire hazard or electric RWARNING shock may occur. CAUTION NOTE Equipment damage may occur. If disregarded, inconvenience only. No risk of personal injury, fire or electric shock. WORD i TABLE OF CONTENTS IMPORTANT .............................................................
