Previous view PRECAUTIONS R DANGER HIGH RF VOLTAGE! NEVER attach an antenna or internal antenna connector during transmission. This may result in an electrical shock or burn. R WARNING! NEVER operate the transceiver with a headset or other audio accessories at high volume levels. The continuous high volume operation may cause a ringing in your ears. If you experience the ringing, reduce the volume level or discontinue use. R WARNING! NEVER operate or touch the transceiver with wet hands. This may result in an electric shock or damage to the transceiver. R WARNING! NEVER let metal, wire or other ob- jects protrude into the transceiver or into connectors on the rear panel. This may result in an electric shock. R WARNING! Immediately turn the transceiver power OFF and remove the power cable if it emits an abnormal odor, sound or smoke. Contact your Icom dealer or distributor for advice. CAUTION: NEVER put the transceiver in any un- stable place (such as on a slanted surface or vibrated place). This may cause injury and/or damage to the transceiver. CAUTION: NEVER put the transceiver's rear panel side down after lifting up the transceiver by holding rack mounting handle. This may scratch the surface of the place or damage the connectors on the transceiver's rear panel. 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. CAUTION: NEVER block any cooling vents on the top, rear or bottom of the transceiver. CAUTION: NEVER expose the transceiver to rain, snow or any liquids. CAUTION: NEVER install the transceiver in a place without adequate ventilation. Heat dissipation may be reduced, and the transceiver may be damaged. CAUTION: The transceiver weighs approximately 23.5 kg (52 lb). Always have two people available to carry, lift or turn over the transceiver. CAUTION: The line-voltage receptacle must be near the transceiver and must be easily accessible. DO NOT use extension cords. DO NOT use harsh solvents such as benzine or al- cohol when cleaning, as they can damage the transceiver's surfaces. DO NOT push the PTT switch when you don't actu- ally desire to transmit. DO NOT use or store the transceiver in areas with temperatures below ±0°C (+32°F) or above +50°C (+122°F). DO NOT place the transceiver in excessively dusty environments or in direct sunlight. DO NOT place 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. BE CAREFUL! NEVER touch the transceiver top cover when transmitting continuously for long periods of time. The top cover may be hot. Use Icom microphones only (supplied or optional). Other manufacturers' microphones have different pin assignments, and connection to the IC-7850 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. iii
