READ THIS INSTRUCTION MANUAL CAREFULLY before attempting to operate the

transceiver.

SAVE THIS INSTRUCTION MANUAL. This

manual contains important safety and operating instructions for the IC-756PRO.

EXPLICIT DEFINITIONS

RWARNING HIGH V OLTAGE! NEVERattach

an antenna or internal antenna connector during transmission.This may result in an electrical shock or burn.

R NEVER apply AC to the [DC13.8V] jack on the

transceiver rear panel.This could cause a ﬁre or ruin the transceiver.

RNEVER 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.

RNEVER let metal, wire or other objects touch any

internal par t or connectors on the rear panel of the transceiver. This may result in an electric shock.

NEVER expose the transceiver to rain, snow or any

liquids. AVOID using or placing the transceiver in areas with

temperatures below –10°C (+14°F) or above +60°C (+140°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 e xhausted.

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 prev ent 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-756PRO may damage the transceiver.

PRECAUTIONS

Versions of the IC-756PRO which display the “CE” symbol on the serial number seal, comply with the European harmonised standard ETS300 684 (EMC product standard for Commercially A vailable Amateur Radio Equipment).

INSTALLATION AND CONNECTIONS

■ Unpacking

After unpacking, immediately report any damage to the delivering carrier or dealer.Keep the shipping cartons.

For a description and a diagram of accessory equipment included with the IC-756PRO, see ‘Supplied ac- cessories’ on p.1 of this manual.

■ Selecting a location

Select a location for the transceiver that allows adequate air circulation, free from extreme heat, cold, or vibrations, and away from TV sets, TV antenna elements, radios and other electro-magnetic sources.

The base of the transceiver has an adjustable stand for desktop use. Set the stand to one of two angles depending on your operating conditions.

■ Grounding

To prevent electrical shock, television interference (TVI), broadcast interference (BCI) and other problems, ground the transceiver through the GROUND terminal on the rear panel.

For best results, connect a heavy gauge wire or strap to a long earth-sunk copper rod. Make the distance between the [GND] terminal and ground as short as possible.

RWARNING: NEVER connect the [GND]

terminal to a gas or electric pipe, since the connection could cause an explosion or electric shock.

■ Antenna connection

For radio communications , the antenna is of critical importance, along with output power and sensitivity. Select antenna(s), such as a well-matched 50 Ω antenna, and feedline.1.5:1 or better of Voltage Standing Wave Ratio (VSWR) is recommended for your desired band. Of course, the transmission line should be a coaxial cable.

When using 1 antenna, use the [ANT1] connector.

CAUTION:Protect your transceiver from lightning

by using a lightning arrestor.

Antenna SWR

Each antenna is tuned for a specified frequency range and SWR may be increased out-of-range. When the SWR is higher than approx. 2.0:1, the transceiver’s power drops to protect the ﬁnal transis- tor.In this case, an antenna tuner is useful to match the transceiver and antenna. Low SWR allows full power for transmitting even when using the antenna tuner.The IC-756PRO has an SWR meter to monitor the antenna SWR continuously.

CAUTION:

Set the transceiver output power for 80 W max. with the [RF POWER] control, otherwise, a protection circuit will activate.

CONNECTING A NON-ICOM LINEAR AMPLIFIER

R WARNING:

Set the transceiver output power and linear amplifier ALC output level ref erring to the linear ampliﬁer instruction manual.

The ALC input level must be in the

range 0 V to –4 V, and the transceiver does not accept positive voltage.Non-matched ALC and RF power settings could cause a fire or ruin the linear ampliﬁer.

The speciﬁcations for the SEND relay are 16 V DC 2 A. If this level is exceeded, a large external relay must be used.

When 2 to 13.8 V is applied to pin 6 of [ACC(2)], the [XVERT] jack is activated for transverter operation and the antenna connectors do not receive or transmit any signals.(p.13)

While receiving, the [XVERT] jack can be activ ated as an input terminal from an external transverter.

While transmitting, the [XVERT] jack outputs signals of the displayed frequency at –20 dBm (22 mV) as signals for the external transverter.

FREQUENCY SETTING

■ VFO description

VFO is an abbreviation of Variable Frequency Oscillator, and traditionally refers to an oscillator.

The transceiver’s VFO is somewhat different.The VFO of the IC-756PRO acts like a computer’s window and can show one frequency and one operating mode.

You can call up a desired frequency to the VFO with the keypad, memo pad-read switch (see p. 55) or the memory transfer function (see p. 53). You can also change the frequency with the tuning dial and select the operating mode with the mode switches.

During dualwatch or split frequency operation, the sub VFO is functional (non-outline, non-spotted, larger frequency characters). While pushing [XFC] during split frequency operation, you can change the transmit readout frequency with the keypad, memo pad-read switch or the memory transfer function.

•Differences between VFO mode and memory mode

VFO MODE

VFO shows a frequency and operating mode. If the frequency or operating mode is changed, the VFO automatically memorizes the new frequency or new operating mode.

When a VFO is selected from another band or memory mode, the frequency and operating mode last used for that VFO appear.

[EXAMPLE]

MEMORY MODE (pgs. 50–54)

Each memory channel shows a frequency and operating mode like a VFO. Even if the frequency or mode is changed, the memory channel does not memorize the new frequency or operating mode.

When the memory channel is selected from another memory channel or VFO mode, the memorized frequency and operating mode appear.

■ Mode selection

■ Twin PBT operation

General PBT (Passband Tuning) function electronically narrows the IF passband width by shifting the IF frequency to slightly outside of the IF ﬁlter passband to reject interference.This transceiver uses the DSP circuit for the PBT function. Moving both [TWIN PBT] controls to the same position shifts the IF. ➥ The LCD shows the passband width and shift fre-

quency graphically.

➥ Push [FILTER] f or 2 sec.to enter the ﬁlter set mode.

Current passband width and shift frequency is displayed in the ﬁlter set mode screen.

➥ To set the [TWIN PBT] controls to the center posi-

tions, push [PBT CLR] for 2 sec.

The variable range depends on the passband width and mode.The edge of the variable range is half of the passband width, and PBT is adjustable in 25 or 50 Hz steps. These controls function as an IF shift control while in AM mode and when the RTTY ﬁlter is turned ON.Only the inner control may function in this case .IF shift is adjustable in 20/40 Hz steps in RTTY (R TTY ﬁl- ter is turned ON) or 150/300/500 Hz steps in AM.

•[TWIN PBT] should normally be set to the center positions (PBT setting is cleared) when there is no interference.

•When PBT is used, the audio tone may be changed.

•Not available for FM mode.

•While rotating [TWIN PBT], noise may occur.This comes

from the DSP unit and does not indicate an equipment malfunction.

RECEIVE AND TRANSMIT

The following modes are available in the IC-756PRO: SSB (LSB/USB), CW, CW-R (CW reverse), RTTY,

RTTY-R (RTTY reverse), AM and FM. Data modes of SSB, AM and FM are also available.

Microphone signals are muted when data mode is selected.

To select a mode of operation, push the desired mode switch momentarily. Push the switch again to toggle between USB and LSB, CW/CW-R and RTTY/RTTYR, AM and FM, if necessary. Push the switch for 2 sec. to toggle between normal and data mode, CW and CW-R, RTTY and RTTY-R, if necessary.

RECEIVE AND TRANSMIT

■ Split frequency operation

Split frequency operation allows you to transmit and receive in the same mode on two different frequencies. The split frequency operation is basically performed using 2 frequencies on the main and sub readouts.

Following is an e xample of setting 21.290 MHz for receiving and 21.310 MHz for transmitting.

q Set 21.290 MHz (USB) in VFO mode.

w Push [SPLIT] momentar ily, then push [CHANGE]

for 2 sec.

•The quick split function is much more convenient for selecting the transmit frequency. See the next section for details.

•The equalized transmit frequency and “”appear on the LCD.

•“TX” appears to show the transmit frequency’s readout.

e Rotate the tuning dial while pushing [XFC] to set

the transmit frequency to 21.310 MHz.

•The transmit frequency can be monitored while pushing [XFC] or using dualwatch.

r Now you can receive on 21.290 MHz and transmit on

21.310 MHz.

To change the transmit and receive frequencies, push [CHANGE] to exchange the main and sub readouts.

DIRECT SHIFT FREQUENCY INPUT

The shift frequency can be entered directly.

q Push [F-INP]. w Enter the desired shift frequency with the digit

keys.

•1 kHz to 1 MHz can be set.

•When you require a minus shift direction, push [ •] in

advance.

e Push [SPLIT].

•The shift frequency is input in the sub readout and the split function is turned ON.

[EXAMPLE]

DUALWATCH FUNCTION

The dualwatch function is convenient for tuning the transmit frequency while monitoring both frequencies used for transmitting and receiving.

SPLIT LOCK FUNCTION

Accidentally releasing the [XFC] switch while rotating the tuning dial changes the receive frequency.T o prevent this, use both the split lock and dial lock functions to change the transmit frequency only. The split lock function cancels the dial lock function while pushing [XFC] during split frequency operation.

The dial lock’s effectiveness during split frequency op- eration can be selected in the set mode for both receive and transmit frequencies; or only the receive frequency. (p. 69)

■ Quick split function

When you ﬁnd a DX station, an important consideration is how to set the split frequency.

When you push the [SPLIT] switch for 2 sec., split frequency operation is turned ON, the sub readout is equalized to the main readout frequency and enters standby for transmit frequency input.

This shortens the time needed to start split frequency operation.

The quick split function is ON by def ault.For your convenience, it can be turned OFF in set mode.(p. 68) In this case, the [SPLIT] switch does not equalize the main and sub readout frequencies.

q Suppose you are operating at 21.290 MHz (USB)

in VFO mode.

w Push [SPLIT] for 2 sec.

•Split frequency operation is turned ON.

•The sub readout is equalized to the main readout fre-

quency.

•The sub readout enters standby for transmit frequency input.

e Rotate the tuning dial to set the transmit frequency;

or, input the transmit frequency using the keypad and [ENT]; or, input a shift frequency using the keypad and [SPLIT].

•The transmit frequency can be monitored while pushing [XFC] or using dualwatch.

■ Automatic antenna selection

The transceiver covers 0.1–60 MHz over 10 bands. Each band key has a band memory which can memorize a selected antenna (ANT1, ANT2, ANT1/RX antenna and ANT2/RX antenna).When you change the operating frequency beyond a band, the previously used antenna is automatically selected for the new band.This function is convenient when you use 2 or 3 antennas.

To use the band memory, enter set mode and conﬁrm that “Auto” is selected as the [ANT] switch item. (p.70)

•When OFF is selected, the [ANT] switch does not function and [ANT1] is always selected.

•When “Manual” is selected, the [ANT] switch functions, howev er, band memory does not function. In this case, you must select an antenna manually.

•When “Auto” is selected (default setting), the antenna tuner ON/OFF condition is also memorized in the band memory.

•When “Auto” or “Manual” is selected, the antenna tuner ON/OFF condition is consistent with the [ANT] switch.

•Antenna switch selection example

Under the following condition, “Auto” should be se- lected as the [ANT] switch set mode item.

- When you use 2 antennas. Under the following conditions, “Manual” should be

selected as the [ANT] switch set mode item.

- When using 1 antenna.

- When using the EX-627 HF AUTOMATIC ANTENNA

SELECTOR

for more than 3 antennas (except for re-

ceive antenna).

- When using an external antenna tuner.

■ Antenna tuner operation

The internal automatic antenna tuner matches the transceiver to the connected antenna automatically. Once the tuner matches an antenna, the variable capacitor angles are memorized as a preset point for each frequency range (100 kHz steps). Therefore, when you change the frequency range, the v ariable capacitors are automatically preset to the memorized point.

CAUTION:

NEVER transmit with the tuner ON

when no antenna is connected.This will damage the transceiver. Be careful of the antenna selection.

RECEIVE AND TRANSMIT

TUNER OPERATION

➥Push the [TUNER] switch to turn the internal an-

tenna tuner ON.The antenna is tuned automatically when the antenna SWR is higher than 1.5:1.

•When the tuner is ON, the [TUNER] switch lights.

[TUNER] switch

MANUAL TUNING

During SSB operation at low voice levels, the internal tuner may not be tuned correctly.In such cases, manual tuning is helpful.

➥Push [TUNER] for 2 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 1.5:1

after 20 sec. of tuning, the [TUNER] switch indicator goes out.

Push [TUNER] for 2 sec.

AUTOMATIC TUNER START (HF bands only)

If you want to deactivate the tuner under conditions of VSWR 1.5:1 or less, use the auto tuner start function and turn the tuner OFF. This function activates the tuner automatically when the SWR exceeds 1.5:1.

This function is turned ON in set mode. (p.69).

PTT TUNER ST ART

The tuner is always tuned when the PTT is pushed after the frequency is changed (more than 1% from last-tuned frequency). This function removes the “push and hold [TUNER]” operation and activates for the ﬁrst transmission on a new frequency.

This function is turned ON in set mode. (p.69).

NOTES:

•If the tuner cannot tune the antenna

Check 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 MHz band)

•the power source voltage/capacity.

If the tuner cannot reduce the SWR to less than 1.5:1 after checking the above, perform the following:

•repeat manual tuning several times.

•tune with a 50 Ω dummy 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 antenna

Some antennas, especially for low bands, have a narrow bandwidth. These antennas may not be tuned at the edge of their bandwidth, therefore, tune such an antenna as follows:

Suppose you have an antenna which has an SWR of

1.5:1 at 3.55 MHz and an SWR of 3:1 at 3.8 MHz.

q Push [TUNER] to turn the antenna tuner ON. w Select CW mode. e Turn OFF the break-in function.(p.5) r Push [TRANSMIT] to set to the transmit condition. t Set 3.55 MHz and key down. y Set 3.80 MHz and key down. u Push [TRANSMIT] to return to the receive condition.

■ Optional external tuner operation

•AH-4/AH-3 HF AUTOMATIC ANTENNA TUNER

The AH-4/AH-3 matches the IC-756PRO to a long wire antenna more than 3 m/10 ft long (3.5 MHz and above) or more than 12 m/40 ft long (1.8 MHz and above).

•See p.20 for the transceiver and AH-4/AH-3 connection.

•See the AH-4/AH-3 instruction manual for AH-4/AH-3 in-

stallation and antenna connection details.

AH-4/AH-3 setting example:

RWARNING: HIGH VOL TAGE!

NEVER touch the antenna element while tuning

or transmitting.

NEVER operate the AH-4/AH-3 without an antenna wire.The tuner and transceiver will be damaged.

NEVER operate the AH-4/AH-3 when it is not grounded.

Transmitting before tuning may damage the transceiver. Note that the AH-4/AH-3 cannot tune when using a 1⁄2 λ long wire or multiple of the operating fre- quency.

•When connecting the AH-4/AH-3, the antenna connector assignments are [ANT2] for the internal tuner and [ANT1] for the AH-4/AH-3.The antenna indicator in the LCD displays “ANT1(EXT)” when the AH-4/AH-3 is connected and selected.

•The AH-3 can be used for HF bands only. It cannot be used for the 50 MHz band.

•AH-4/AH-3 operation

Tuning is required for each frequency. Be sure to re-tune the antenna before transmitting when you change the frequency—even slightly.

q Set the desired frequency in an HF or 50 MHz

band for using with the AH-4. Set the desired frequency in an HF band for using with the AH-3.

•The AH-4/AH-3 will not operate on frequencies outside of ham bands.

w Push [TUNER] for 2 sec.

•The [TUNER] light blinks while tuning.

e The [TUNER] light lights constantly when tuning is

complete.

•When the connected wire cannot be tuned, the [TUNER] light goes out, the AH-4/AH-3 is bypassed and the antenna wire is connected to the antenna connector on the transceiver directly.

r To bypass the AH-4/AH-3 manually, push

•Selecting a memory channel using the memory channel screen

q Push [EXIT] one or more times to close a m ulti-

function screen, if necessary.

w Push [(F-3)MEMORY] to select the memory chan-

nel screen.

•[(F-5)WIDE] toggles the standard and wide screens.

e Rotate the tuning dial while pushing [(F-2)SET] to

select the desired memory channel.

•[Y] and [Z] can also be used.

r Push [EXIT] to exit the memory channel screen.

•Conﬁrming programmed memory channels

q Select the memor y channel screen as described

above.

w Rotate the tuning dial while pushing [(F-1)ROLL]

to scroll the screen.

e Push [(F-2)SET] to select the highlighted memory

channel, if desired.

r Push [EXIT] to exit the memory channel screen.

•Setting a memory channel as a select memory

Select memory channels are used for select memory scan. Select memory scan repeatedly scans the select memory channels only. This is useful to speedup the memory scan interval. Of course, select memory channels are also scanned during normal memor y scan.

q Select the memor y channel screen as described

at left.

w Rotate the tuning dial while pushing [(F-2)SET] to

select the desired memory channel.

•[Y] and [Z] can also be used.

e Push [(F-3)SELECT] to set the memor y channel

as a select memory or not.

r Repeat steps w to e to program another memory

channel as a select memory channel, if desired.

t Push [EXIT] to exit the memory channel screen.

Setting select memory channels is also possible in the scan screen.

MEMORY OPERATION

■ Memo pads

The transceiver has a memo pad function to store frequency and operating mode for easy write and recall. The memo pads are separate from memory channels.

The default number of memo pads is 5, however, this can be increased to 10 in set mode if desired. (p.71)

Memo pads are convenient when you want to memorize a frequency and operating mode temporarily , such as when you ﬁnd a DX station in a pile-up, or when a desired station is busy for a long time and you want to temporarily search for other stations.

Use the transceiver’s memo pads instead of relying on hastily scribbled notes that are easily misplaced.

•Writing frequencies and operating modes into memo pads

You can simply write the accessed readout frequency and operating mode by pushing [MP-W].

When you write a 6th frequency and operating mode, the oldest written frequency and operating mode are automatically erased to make room for the new settings.

Each memo pad must have its own unique combination of frequency and operating mode; memo pads having identical settings cannot be written.

MEMO PADS

•Calling up a frequency from a memo pad

You can simply call up the desired frequency and operating mode of a memo pad by pushing [MP-R] one or more times.

•Both VFO and memory modes can be used.

•The frequency and operating mode are called up, starting

from the most recently written.

When you call up a frequency and an operating mode from memo pads with [MP-R], the previously displayed frequency and operating mode are automatically stored in a temporary pad. The frequency and operating mode in the temporary pad can be recalled by pushing [MP-R] one or more times.

•You may think there are 6 memo pads because 6 different

frequencies (5 are in memo pads and 1 is in the temporary pad) are called up by [MP-R].

If you change the frequency or operating mode called up from a memo pad with the tuning dial, etc., the frequency and operating mode in the temporary pad are erased.
