PRECAUTIONS R WARNING RF EXPOSURE! This device emits Radio Frequency (RF) energy. Extreme caution should be observed when operating this device. If you have any questions regarding RF exposure and safety standards please refer to the Federal Communications Commission Office of Engineering and Technology's report on Evaluating Compliance with FCC Guidelines for Human Radio Frequency Electromagnetic Fields (OET Bulletin 65). AVOID using or placing the transceiver in areas with temperatures below ­10°C (+14°F) or above +50°C (+122°F). Be aware that temperatures on a vehicle's dashboard can exceed 80°C (+176°F), resulting in permanent damage to the transceiver 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. Place unit in a secure place to avoid inadvertent use by children. 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. The LCD display may have cosmetic imperfections that appear as small or dark spots. This is not a malfunction or defect, but a normal characteristic of LCD displays. Use Icom microphones only (supplied or optional). Other manufacturer's microphones have different pin assignments, and connection to the IC-756PROIII may damage the transceiver. For U.S.A. only R WARNING HIGH VOLTAGE! NEVER attach an antenna or internal antenna connector during transmission. This may result in an electrical shock or burn. RWARNING! 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 result in reduced 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 NEVER apply AC to the [DC13.8V] jack on the transceiver rear panel. This could cause a fire or ruin the transceiver. R NEVER apply more than 16 V DC, such as a 24 V battery, to the [DC13.8V] jack on the transceiver rear panel. This could cause a fire or ruin the transceiver. R NEVER let metal, wire or other objects touch any internal part or connectors on the rear panel of the transceiver. This may result in an electric shock. R NEVER expose the transceiver to rain, snow or any liquids. R NEVER installing the transceiver in a place without adequate ventilation. Heat dissipation may be affected, 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. CAUTION: Changes or modifications to this device, not expressly approved by Icom Inc., could void your authority to operate this device under FCC regulations. ii TABLE OF CONTENTS IMPORTANT

(p. 100) #8 #9 When the quick tuning step is OFF, push for 1 sec. to turn the 1 Hz tuning step ON and OFF. · 1 Hz indications appear in both readouts and the frequency can be changed in 1 Hz steps. When the quick tuning step is ON, push for 1 sec. to enter the quick tuning step set mode. $2 MEMORY CLEAR SWITCH [M-CL] (p. 81) Clears the selected readout memory channel contents when pushed for 1 sec. in memory mode. · The channel becomes a blank channel. · This switch does not function in VFO mode. $3 MEMORY WRITE SWITCH [MW] (p. 79) Stores the selected readout frequency and operating mode into the displayed memory channel when pushed for 1 sec. · This function is available both in VFO and memory modes. $1 QUICK TUNING SWITCH [TS] (p. 26) Turns the quick tuning step ON and OFF. · While the quick tuning indicator, "Z," is displayed above the frequency indication, the frequency can be changed in programmed kHz steps. · 0.1, 1, 5, 9, 10, 12.5, 20 and 25 kHz quick tuning steps are available for each operating mode independently. Quick tuning indicator ANT 1 METER Po YZ $4 MEMORY UP/DOWN SWITCHES [Y]/[Z] (p. 77) Push to select the memory channel number for the selected readout. · Memory channels can be selected both in VFO and memory modes. Select the desired memory channel directly after pushing [(F-INP)ENT] and a memory channel number. $5 MEMO PAD-READ SWITCH [MP-R] (p. 82) Each pushing calls up a frequency and operating mode in a memo pad. The 5 (or 10) most recently programmed frequencies and operating modes can be recalled, starting from the most recent. · The memo pad capacity can be expanded from 5 to 10 in set mode for your convenience.

Pushing the same key 2 or 3 times calls up other stacked frequencies in the band. (p. 24) · Icom's triple band stacking register memorizes 3 frequencies in each band. %1 VFO/MEMORY SWITCH [VFO/MEMO] Switches the selected readout operating mode between the VFO mode and memory mode when pushed. (pgs. 23, 77) Transfers the memory contents to VFO when pushed for 1 sec. (p. 80) %2 MAIN/SUB·M.SCOPE SWITCH [MAIN/SUB·M.SCOPE] Push momentarily to select access to the main or sub readout. (p. 23) · The sub readout frequency is displayed in outline or mesh font. The sub readout functions only during split operation or dualwatch. 1 After pushing [(F-INP)ENT], enters a keyed frequency or memory channel. Pushing [(FYZ INP)ENT] or [Y]/[Z] is necessary at the end. (pgs. 25, 77) · e.g. to enter 14.195 MHz, push [(F-INP)ENT] [1] [4] [·] [1] [9] [5] [(F-INP)ENT]. $7 MEMO PAD-WRITE SWITCH [MP-W] (p. 82) Programs the selected readout frequency and operating mode into a memo pad. · The 5 most recent entries remain in memo pads. · The transmit frequency is programmed when pushed together with [XFC]. · The memo pad capacity can be expanded from 5 to 10 in set mode for your convenience. (p. 102) Push for 1 sec. to turn the mini spectrum scope screen indication ON and OFF. (p. 55) · The mini spectrum scope screen can be indicated with another screen, such as memory, set mode screen, simultaneously. $8 SPLIT SWITCH [SPLIT] (p. 71) Turns the split function ON and OFF when pushed. Turns the split function ON, equalizes the sub readout frequency to the main readout and sets the sub readout for frequency input when pushed for 1 sec. in non-FM modes. (Quick split function) · The offset frequency is shifted from the main readout frequency in FM mode. (pgs. 52, 100) · The quick split function can be turned OFF using set mode. (p. 100) %3 LCD FUNCTION DISPLAY (See p. 9 for details.) Shows the operating frequency, function switch menus, spectrum scope screen, memory channel screen, set mode settings, etc. Turns the split function ON and shifts the sub readout frequency after input an offset (±4 MHz in 1 kHz steps). $9 DUALWATCH SWITCH [DUALWATCH] (p. 63) Turns the dualwatch function ON and OFF when pushed. Turns the dualwatch function ON and equalizes the sub readout frequency to the main readout when pushed for 1 sec. (Quick dualwatch function) · The quick dualwatch function can be turned OFF using set mode. (p. 98) %0 MAIN/SUB CHANGE SWITCH [CHANGE] Switches the frequency and selected memory channel between main and sub readouts when pushed. · Switches between transmit frequency and receive frequency when the split frequency function is ON. (p. 71) Equalizes the sub readout frequency to the main readout frequency when pushed for 1 sec. 8 1
