Thismanual contains important safety and operating in-structions for the IC-756PROII.EXPLICIT DEFINITIONSRWARNING HIGH VOLTAGE! NEVER at-tach an antenna or internal antenna connector duringtransmission. This may result in an electrical shock orburn.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 useby children.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 ex-hausted.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 when op-erating 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-756PROII maydamage the transceiver.PRECAUTIONSSpurious 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 MHzWORD DEFINITIONRRWARNING Personal injury, fire hazard or electricshock may occur.CAUTION Equipment damage may occur.NOTEIf disregarded, inconvenience only.

314INSTALLATION AND CONNECTIONS■UnpackingAfter unpacking, immediately report any damage to thedelivering carrier or dealer. Keep the shipping cartons.For a description and a diagram of accessory equip-ment included with the IC-756PROII, see ‘Supplied ac-cessories’ on p. 1 of this manual.■Selecting a locationSelect a location for the transceiver that allows ade-quate air circulation, free from extreme heat, cold, orvibrations, and away from TV sets, TV antenna ele-ments, radios and other electro-magnetic sources.The base of the transceiver has an adjustable standfor desktop use. Set the stand to one of two angles de-pending on your operating conditions.■GroundingTo prevent electrical shock, television interference(TVI), broadcast interference (BCI) and other prob-lems, ground the transceiver through the GROUNDterminal on the rear panel.For best results, connect a heavy gauge wire or strapto a long earth-sunk copper rod. Make the distance be-tween the [GND] terminal and ground as short as pos-sible.RWARNING: NEVER connect the [GND]terminal to a gas or electric pipe, since the connec-tion could cause an explosion or electric shock.■Antenna connectionFor radio communications, the antenna is of critical im-portance, along with output power and sensitivity. Se-lect antenna(s), such as a well-matched 50 Ωantenna,and feedline. 1.5:1 or better of Voltage Standing WaveRatio (VSWR) is recommended for your desired band.Of course, the transmission line should be a coaxialcable.When using 1 antenna, use the [ANT1] connector.CAUTION: Protect your transceiver from lightningby using a lightning arrestor.Antenna SWREach antenna is tuned for a specified frequencyrange and SWR may be increased out-of-range.When the SWR is higher than approx. 2.0:1, thetransceiver’s power drops to protect the final transis-tor. In this case, an antenna tuner is useful to matchthe transceiver and antenna. Low SWR allows fullpower for transmitting even when using the antennatuner. The IC-756PROII has an SWR meter to mon-itor the antenna SWR continuously.PL-259 CONNECTOR INSTALLATION EXAMPLE30 mm ≈9⁄8in 10 mm ≈3⁄8in 1–2 mm ≈1⁄16 in30 mm10 mm (soft solder)10 mm1–2 mmsolder solderSoftsolderCoupling ringSlide the coupling ring down.

224FREQUENCY SETTING■VFO descriptionVFO is an abbreviation of Variable Frequency Oscilla-tor, and traditionally refers to an oscillator.The transceiver’s VFO is somewhat different. The VFOof the IC-756PROII acts like a computer’s window andcan show one frequency and one operating mode.You can call up a desired frequency to the VFO withthe keypad, memo pad-read switch (see p. 56) or thememory transfer function (see p. 54). You can alsochange the frequency with the tuning dial and selectthe operating mode with the mode switches.During dualwatch or split frequency operation, the subVFO is functional (non-outline, non-spotted, larger fre-quency characters). While pushing [XFC] during splitfrequency operation, you can change the transmitreadout frequency with the keypad, memo pad-readswitch or the memory transfer function.METERPoANT1BWBW 2.4k2.4k SFTSFT 0VFOVFOFIL2FIL2USBUSBqw:ppTXTX1CWCWqr.qpp.pp21.076.5021.076.50SelectTUNING DIALMEMORYCHANNELMODESWITCHESMEMO PADKEYPAD(BAND KEY)TransferTransfer TransferChange21.295 MHz 28.025 MHz 7.001 MHz•Differences between VFO mode and memory modeVFO MODEVFO shows a frequency and operating mode.

495RECEIVE AND TRANSMIT■Antenna tuner operationThe internal automatic antenna tuner matches thetransceiver to the connected antenna automatically.Once the tuner matches an antenna, the variable ca-pacitor angles are memorized as a preset point foreach frequency range (100 kHz steps). Therefore,when you change the frequency range, the variablecapacitors are automatically preset to the memorizedpoint.CAUTION: NEVER transmit with the tuner ONwhen no antenna is connected. This will damagethe transceiver. Be careful of the antenna selection.TUNER OPERATION➥Push the [TUNER] switch to turn the internal an-tenna tuner ON. The antenna is tuned automati-cally when the antenna SWR is higher than 1.5:1.•When the tuner is ON, the [TUNER] switch lights.[TUNER] switchMANUAL TUNINGDuring SSB operation at low voice levels, the internaltuner may not be tuned correctly. In such cases, man-ual tuning is helpful.➥Push [TUNER] for 1 sec., to start manual tuning.•A side tone is emitted and [TUNER] blinks while tuning.•If the tuner cannot reduce the SWR to less than 1.5:1after 20 sec. of tuning, the [TUNER] switch indicatorgoes out.Push [TUNER] for 1 sec.AUTOMATIC TUNER START (HF bands only)If you want to deactivate the tuner under conditionsof VSWR 1.5:1 or less, use the auto tuner start func-tion and turn the tuner OFF. This function activatesthe tuner automatically when the SWR exceeds 1.5:1.This function is turned ON in set mode. (p. 71).PTT TUNER STARTThe tuner is always tuned when the PTT is pushedafter the frequency is changed (more than 1% fromlast-tuned frequency). This function removes the“push and hold [TUNER]” operation and activates forthe first transmission on a new frequency. This function is turned ON in set mode. (p. 71).NOTES:•If the tuner cannot tune the antennaCheck the following and try again:•the [ANT] connector selection.•the antenna connection and feedline.•the unaltered antenna SWR. (Less than 3:1 for HF bands; Less than 2.5:1 for 50 MHz band)•the transmit power. (8 W for HF bands; 15 W for 50 MHzband)•the power source voltage/capacity.If the tuner cannot reduce the SWR to less than 1.5:1after checking the above, perform the following:•repeat manual tuning several times.•tune with a 50 Ωdummy load and re-tune the antenna.•turn power OFF and ON.•adjust the antenna cable length.(This is effective for higher frequencies in some cases.)•Tuning a narrow bandwidth antennaSome antennas, especially for low bands, have a nar-row bandwidth. These antennas may not be tuned atthe edge of their bandwidth, therefore, tune such anantenna as follows:Suppose you have an antenna which has an SWR of1.5:1 at 3.55 MHz and an SWR of 3:1 at 3.8 MHz.qPush [TUNER] to turn the antenna tuner ON.wSelect CW mode.eTurn OFF the break-in function. (p. 5)rPush [TRANSMIT] to set to the transmit condition.tSet 3.55 MHz and key down.ySet 3.80 MHz and key down.uPush [TRANSMIT] to return to the receive condition.

The tuner and transceiver will be damaged.NEVER operate the AH-4/AH-3 when it is notgrounded.Transmitting before tuning may damage the trans-ceiver. Note that the AH-4/AH-3 cannot tune whenusing a 1⁄2λlong wire or multiple of the operating fre-quency.•When connecting the AH-4/AH-3, the antennaconnector assignments are [ANT2] for the internaltuner and [ANT1] for the AH-4/AH-3.

(p. 73)Memo pads are convenient when you want to memo-rize a frequency and operating mode temporarily, suchas when you find a DX station in a pile-up, or when adesired station is busy for a long time and you want totemporarily search for other stations.Use the transceiver’s memo pads instead of relying onhastily scribbled notes that are easily misplaced.•Writing frequencies and operatingmodes into memo padsYou can simply write the accessed readout frequencyand operating mode by pushing [MP-W].When you write a 6th frequency and operating mode,the oldest written frequency and operating mode areautomatically erased to make room for the new set-tings.Each memo pad must have its own unique combi-nation of frequency and operating mode; memopads having identical settings cannot be written.Displayed frequency and modePushNewestThe oldest written frequencyand mode are erased.OldestMP-Wwq.wii.wwUSBwq.wuy.ppUSBwq.pwr.twUSBwq.pqi.pyUSBqr.qiw.rpUSBqr.qot.ppUSBMEMOPADS•Calling up a frequency from a memo padYou can simply call up the desired frequency and op-erating mode of a memo pad by pushing [MP-R] sev-eral times.•Both VFO and memory modes can be used.•The frequency and operating mode are called up, startingfrom the most recently written.When you call up a frequency and an operating modefrom memo pads with [MP-R], the previously dis-played frequency and operating mode are automati-cally stored in a temporary pad.

1685ABOUT CEINSTALLATION NOTESFor amateur base station installations it is recommended thatthe forwards clearance in front of the antenna array is calculatedrelative to the EIRP (Effective Isotropic Radiated Power). Theclearance height below the antenna array can be determined inmost cases from the RF power at the antenna input terminals.As different exposure limits have been recommended for differ-ent frequencies, a relative table shows a guideline for installa-tion considerations.Below 30 MHz, the recommended limits are specified in terms ofV/m or A/m fields as they are likely to fall within the near-field re-gion. Similarly, the antennae may be physically short in terms ofelectrical length and that the installation will require some an-tenna matching device which can create local, high intensitymagnetic fields. Analysis of such MF installations is best consid-ered in association with published guidance notes such as theFCC OET Bulletin 65 Edition 97-01 and its annexes relative toamateur transmitter installations. The EC recommended limitsare almost identical to the FCC specified ‘uncontrolled’ limits andtables exist that show pre-calculated safe distances for differentantenna types for different frequency bands. Further informationcan be found at http://www.arrl.org/.•Typical amateur radio installationExposure distance assumes that the predominant radiation pat-tern is forwards and that radiation vertically downwards is atunity gain (sidelobe suppression is equal to main lobe gain). Thisis true of almost every gain antenna today. Exposed persons areassumed to be beneath the antenna array and have a typicalheight to 1.8 m.The figures assume the worst case emission of constant carrier.For the bands 10 MHz and higher the following power densitylimits have been recommended:10 – 400 MHz 2 W/sq m435 MHz 2.2 W/sq mEIRP clearance heights by frequency bandWatts 10–2 m 70 cm 23 cm 13cm and above1 2.1 m 2 m 2 m 2 m10 2.8 m 2.7 m 2.5 m 2.3 m25 3.4 m 3.3 m 2.7 m 2.5 m100 5 m 4.7 m 3.6 m 3.2 m1000 12 m 11.5 m 7.3 m 6.3 mForward clearance, EIRP by frequency bandWatts 10–2 m 70 cm 23 cm 13cm and above100 2 m 2 m 1.1 m 0.7 m1000 6.5 m 6 m 3.5 m 3 m10,000 20 m 18 m 11 m 7 m100,000 65 m 60 m 35 m 29 mIn all cases any possible risk depends on the transmitter beingactivated for long periods. (actual recommendation limits arespecified as an average during 6 minutes) Normally the trans-mitter is not active for long periods of time. Some radio licenseswill require that a timer circuit automatically cuts the transmitterafter 1–2 minutes etc.Similarly some types of transmitter, SSB, CW, AM etc. have alower ‘average’ output power and the assessed risk is evenlower.
