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. only Caution: Changes or modifications to this transceiver, not expressly approved by Icom Inc...
