![iIMPORTANTREAD THIS INSTRUCTION MANUALCAREFULLY before attempting to operate thetransceiver.SAVE THIS INSTRUCTION MANUAL. Thismanual contains important safety and operating in-structions for the IC-756PRO.EXPLICIT DEFINITIONSRWARNING HIGH VOLTAGE! NEVER attachan antenna or internal antenna connector during trans-mission. This may result in an electrical shock or burn.RNEVER apply AC to the [DC13.8V] jack on thetransceiver rear panel. This could cause a fire or ruinthe transceiver.RNEVER apply more than 16 V DC, such as a 24 Vbattery, to the [DC13.8V] jack on the transceiver rearpanel. This could cause a fire or ruin the transceiver.RNEVER let metal, wire or other objects touch anyinternal part or connectors on the rear panel of thetransceiver. This may result in an electric shock.NEVER expose the transceiver to rain, snow or anyliquids.AVOID using or placing the transceiver in areas withtemperatures below –10°C (+14°F) or above +60°C(+140°F). Be aware that temperatures on a vehicle’sdashboard can exceed 80°C (+176°F), resulting in per-manent damage to the transceiver if left there for ex-tended periods.AVOID placing the transceiver in excessively dusty en-vironments or in direct sunlight.AVOID placing the transceiver against walls or puttinganything on top of the transceiver. This will obstructheat dissipation.Place unit in a secure place to avoid inadvertent use by chil-dren.During mobile operation, DO NOT operate the trans-ceiver without running the vehicle’s engine. Whentransceiver power is ON and your vehicle’s engine isOFF, the vehicle’s battery will soon become exhausted.Make sure the transceiver power is OFF before start-ing the vehicle. This will avoid possible damage to thetransceiver by ignition voltage spikes.During maritime mobile operation, keep the transceiverand microphone as far away as possible from the mag-netic navigation compass to prevent erroneous indica-tions.BE CAREFUL! The heatsink will become hot whenoperating the transceiver continuously for long periods.BE CAREFUL! If a linear amplifier is connected, setthe transceiver’s RF output power to less than the lin-ear amplifier’s maximum input level, otherwise, the lin-ear amplifier will be damaged.Use Icom microphones only (supplied or optional).Other manufacturer’s microphones have different pinassignments, and connection to the IC-756PRO maydamage the transceiver.PRECAUTIONSVersions of the IC-756PRO which display the “CE”symbol on the serial number seal, comply with theEuropean harmonised standard ETS300 684(EMC product standard for Commercially AvailableAmateur Radio Equipment).WORDR WARNINGCAUTIONNOTEDEFINITIONPersonal injury, fire hazard or electric shock may occur.If disregarded, inconvenience only. No risk of personal injury, fire or electric shock.Equipment damage may occur.Spurious may be received near the following frequencies.These are made in the internal circuit and does not indicate atransceiver malfunction:6.144 MHz, 8.000 MHz, 12.288 MHz, 12.890 MHz (when spectrum scope is ON), 18.433 MHz, 24.573 MHz](https://usermanual.wiki/ICOM-orporated/IC-756PRO.Manual/User-Guide-72054-Page-2.png)
