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).
R WARNING HIGH VOLTAGE! NEVER at-
tach 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.
RCAUTION! 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.
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 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.
RNEVER installing the transceiver in a place with-
out adequate ventilation. Heat dissipation may be affected, and the transceiver may be damaged.
RNEVER operate or touch the transceiver with wet
hands. This may result in an electric shock or damage
to the transceiver.
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
CAUTION: Changes or modifications to this device,
not expressly approved by Icom Inc., could void your
authority to operate this device under FCC regulations.

INST ALLATION 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-756PROIII, see ‘Supplied
accessories’ on p. i 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 electromagnetic 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: NEVERconnect 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 transistor. 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-756PROIII has an SWR meter to monitor the antenna SWR continuously.

■ 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-756PROIII 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. 82) or the
memory transfer function (see p. 80). 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. 77–81)
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.

BASIC OPERATION

The triple band stacking register provides 3 memories
in one band. 3 sets of a frequency and operating mode
on each band are automatically stored when used.
If a band key is pushed once, the frequency and operating mode last used are called up. When the key is
pushed again, another stored frequency and operating
mode are called up.
This function is convenient when you operate 3 operating modes on one band. For example, one register
is used for a CW frequency, another for an SSB frequency and the other one for an RTTY frequency.
See the table below for a list of the band available and
the default settings for each band.

■ Squelch and receive (RF) sensitivity
Adjusts the RF gain and squelch threshold level. The
squelch removes noise output from the speaker
(closed position) when no signal is received.
•The squelch is particularly effective for FM. It is also available for other modes.
•12 to 1 o’clock position is recommended for any setting of
the [RF/SQL] control.
•The control can be set as ‘Auto’ (RF gain control in SSB,
CW and RTTY; squelch control in AM and FM) or squelch
control (RF gain is fixed at maximum) in set mode as follows. (p. 99)
Adjusting RF gain (Receive sensitivity)
Normally, [RF/SQL] is set to the 11 o’clock position.
Rotate [RF/SQL] to the 11 o’clock position for maximum sensitivity.
•Rotating counterclockwise from the maximum position reduces sensitivity.
• The S-meter indicates receive sensitivity.
Adjusting squelch (Removing non-signal noise)
Rotate [RF/SQL] clockwise when receiving no signal,
until the noise just disappears.
• [RX] indicator light goes out.
•Rotating [RF/SQL] past the threshold point invokes the S-
meter squelch— this allows you to set a minimum signal
level needed to open the squelch.
•When setting as RF gain/squelch control
•When functioning as RF gain control
(Squelch is fixed open; SSB, CW, RTTY only)
•When functioning as squelch control
(RF gain is fixed at maximum.)
While rotating the RF gain control, noise may be
heard. This comes from the DSP unit and does not
indicate an equipment malfunction.

About 5 MHz band operation (USA version only)
Operation on the 5 MHz band is allowed on 5 discrete
frequencies and must adhere to the following:
• USB mode
• Maximum of 50 watts ERP
(Effective Radiated Power)
• 2.8 kHz bandwidth
It is the operator’s responsibility to set all controls so
that the transmission in this band meets the stringent
conditions under which we may use these frequencies.
NOTE: We recommend that you store these frequencies, mode and filter settings into the memory
channel for easy recall.
*The channel center frequencies that are specified
by the FCC, show the center frequency of their
passband. However, the IC-756PROIII displays
carrier point frequency, so set 1.5 kHz below from
FCC channel center frequency.

■ Repeater operation
A repeater amplifies received signals and retransmits
them at a different frequency. When using a repeater,
the transmit frequency is shifted from the receive frequency by an offset frequency. A repeater can be accessed using split frequency operation with the shift
frequency set to the repeater’s offset frequency.
For accessing a repeater which requires a repeater
tone, set the repeater tone frequency in set mode
as described below.
q Set the offset frequencies (HF, 50 MHz) and turn
ON the quick split function in set mode (others) in
advance. (p. 69)
w Push [VFO/MEMO] to select VFO mode.
e Push the desired band key.
r Push [AM/FM] several times to select FM mode.

quency).
y Push [SPLIT] for 1 sec. to start repeater operation.
• Repeater tone is turned ON automatically.
•Shifted transmit frequency and “TX” appear in the sub
readout.
•The transmit frequency can be monitored while pushing
[XFC] or using dualwatch.
u Push and hold [PTT] to transmit; release [PTT] to
receive.
i To return to simplex, push [SPLIT] momentarily to
clear the sub display.

The “P.AMP 2” is a high gain receive amplifier. When
the “P.AMP 2” is used during times of strong electric
fields, distortion sometimes results. In such cases,
use the transceiver with the “P.AMP 1” or “P.AMP
OFF” setting.
The “P.AMP 2” is most effective when:
•Used on bands above 24 MHz and when electric
fields are weak.
•Receive sensitivity is insufficient during low gain, or
while using a narrow band antenna (such as small
loop, a Beverage antenna or a short Yagi antenna,
etc.) is used.
[P.AMP]
■ Attenuator
The attenuator prevents a desired signal from distortion when very strong signals are near the desired frequency or when very strong electric fields, such as
from broardcasting stations, are near your location.
➥ Push [ATT] several times to set the attenuator 6
dB, 12 dB, 18 dB or OFF.
•“ATT 6dB,” “ATT 12dB,” “ATT 18dB” and “ATT OFF” appears respectively.

■ RIT function
The RIT (Receive Increment Tuning) function compensates for off-frequencies of the communicating
station.
The function shifts the receive frequency up to ±9.999
kHz in 1 Hz steps (10 Hz steps when cancelling the 1
Hz step readout) without moving the transmit frequency.
• See #1 on p. 5 for function description.
q Push [RIT] to turn the RIT function ON and OFF.
•“ ” and the shifting frequency appear when the
function is ON.
w Rotate the [RIT/∂∂TX] control.
e To reset the RIT frequency, push [CLEAR] for
1 sec.
•Push [CLEAR] momentarily to reset the RIT frequency
when the quick RIT/∂TX clear function is ON. (p. 103)
r To cancel the RIT function, push [RIT] again.

When RIT and ∂TX are ON at the same time, the
[RIT/∂∂TX] control shifts both the transmit and receive frequencies from the displayed frequency at
the same time.
•Calculate function
The shift frequency of the RIT (or ∂TX) function can
be added/subtracted to the displayed frequency.
While displaying the RIT (and/or ∂TX) shift frequency, push [RIT] (or [∂∂TX]) for 1 sec.
•Practical example
When you find a DX station on 21.025 MHz/CW and
the station is picking up stations transmitting slightly
up from 21.025 MHz.
q Push [RIT] and [∂∂TX] to turn both the RIT and
∂TX functions ON.
w Rotate [RIT/∂∂TX] to find the DX station’s receive
frequency.
e When you find the DX station’s receive frequency,
push [RIT] to turn the RIT function OFF.
•Now you can transmit the DX station’s receive frequency and receive the DX station’s transmit frequency (21.025 MHz).
r Start transmitting while the station is standing by.

■ 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] for 1 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 1 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 (RTTY
filter is turned ON) or 150/300/500 Hz steps in AM.
•[TWIN PBT] should normally be set to the center posi-
tions (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.

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)ENT].
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. To 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 operation can be selected in the set mode for both receive and transmit frequencies; or only the receive
frequency. (p. 100)

When you are searching for DX stations and you
suspect that a DX station may say “up ‘X’ kHz” for
their receive frequency:
OPERATION 1
q Push [SPLIT] for 1 sec. to standby for split oper-
ation.
w If the DX station’s operator says “up 10 kHz”:
• Push [1], [0] then [SPLIT].
•Or, rotate the tuning dial.
OPERATION 2
If the DX station’s operator says “down 5 kHz” before you enter standby for split operation:
➥ Push [(F-INP)ENT], [•], [5] then [SPLIT].
•The split function is turned ON and “5 kHz down” frequency is entered in the sub readout.
PRACTICAL EXAMPLE
When you receive a pile-up and you want to start
split frequency operation to simplify picking out stations:
q Push [SPLIT] momentarily and push [CHANGE]
for 1 sec.
•The sub readout frequency is equalized to the main
readout frequency and “ ” appears.
w Rotate the tuning dial to set your receive fre-
quency in the main readout.
e Announce your receive frequency.
r After you catch one of the calling stations’ call
signs, push and hold the PTT switch to respond.
•While pushing [XFC], you can monitor your transmit
frequency.
SPLIT
PRACTICAL EXAMPLE
When you find a DX station, an important consideration is how to set the split frequency.
When you push the [SPLIT] switch for 1 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 default. For your convenience, it can be turned OFF in set mode. (p. 100)
In this case, the [SPLIT] switch does not equalize the
main and sub readout frequencies.

VOICE RECORDER FUNCTIONS
■ Digital voice recorder
The transceiver has a total of 8 memory channels, 4
each for transmit and receive, of digital voice memories. A maximum message length of 15 sec. can be
recorded in each receive channel, and a total message
length of 90 sec. can be recorded in transmit channels.
Providing a transmission memory is very convenient
for repeated CQ and number transmissions at contest
times, as well as when making consecutive calls in
DX’pedition.
•Recording a received audio
q Push [EXIT/SET] several times to close a multi-
function screen, if necessary.
w Select the desired mode by pushing [SSB],
[CW/RTTY] or [AM/FM].
e Push [(F-2)VOICE] to call up the voice recorder
screen.
•If the transmit voice memory channel (T1–T4) appears,
push [(F-5)T/R] to select receive voice memory channel.
r Push the desired memory channel switch,
[(F-1)R1]– [(F-4)R4], for 1 sec. to start recording.
• “REC” flashes and the recording timer counts up.
•The operating frequency, mode and current time are
programmed as the memory names automatically.
• Previously recorded contents are cleared.
t Push the selected memory channel switch,
[(F-1)R1]– [(F-4)R4], again to stop recording.
• Recording is automatically terminated after 30 min.
IMPORTANT!
Push one of [(F-1)R1]–[(F-4)R4] to stop recording before, or when 15 sec. has passed from the
start of recording.
The voice recorder memory records the 15 sec.
(max.) of audio before one of [(F-1)R1]–[(F-4)
R4] is pushed.
For example, when recording 20 sec. of audio,
the first 5 sec. audio will be over-recorded with
the last 5 sec., so that the total of audio
recorded is 15 sec. only.
y Push [EXIT/SET] twice to exit the voice memory
screen.
•Playing the recorded audio
q Push [EXIT/SET] several times to close a multi-
function screen, if necessary.

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. 102)
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.

•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] sev-
eral 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] several 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.

■ Scan types
■ Preparation
•Channels
For programmed scan:
Program scan edge frequencies into scan edge memory channels P1 and P2.
For
∂
F scan:
Set the ∂F span (∂F scan range) in the scan screen.
For memory scan:
Program 2 or more memory channels except scan
edge memory channels.
For select memory scan:
Designate 2 or more memory channels as select memory channels. To designate the channel as a select
memory channel, choose a memory channel, then
push [(F-3)SELECT] in the scan screen (memory
mode) or in the memory channel screen.
•Scan resume ON/OFF
You can select the scan to resume or cancel when detecting a signal, in set mode. Scan resume ON/OFF
must be set before operating a scan. See p. 87 for
ON/OFF setting and scan resume condition details.
•Scan speed
Scan speed can be selected from 2 levels, high or low,
in set mode. See p. 87 for details.
•Squelch condition
•The scan function can be used on the main readout only.
•You can operate a scan while operating on a frequency using
the dualwatch or split functions. See p. 63 for details.
SQUELCH
CLOSED
SQUELCH
OPEN
Scan stops when detecting a signal.
If you set scan resume ON in set mode, the
scan pauses for 10 sec. when detecting a
signal, then resumes. When a signal disappears while scan is paused, scan resumes
2 sec. later.
The scan continues
until it is stopped
manually, and does
not pause even if it
detects signals.
Scan pauses on
each channel when
the scan resume is
ON; not applicable
when OFF.

ANTENNA TUNER OPERATION
■ 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. 101)
•When OFF is selected, the [ANT] switch does not function
and [ANT1] is always selected.
•When “Manual” is selected, the [ANT] switch functions,
however, 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 selected 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 an external antenna selector for more
than 3 antennas (except for receive 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 variable
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.
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]
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 1 sec., to start manual tuning.
•Aside 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 1 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. 101).
PTT TUNER START
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. 101).
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. (pgs. 4, 66)
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 matches the IC-756PROIII to a long wire
antenna more than 7 m/23 ft long (3.5 MHz and above).
The AH-3 matches the IC-756PROIII 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. 18 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:
RDANGER: HIGH VOLTAGE!
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
⁄2λ 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 use with the AH-4. Set the desired frequency in an HF band for use with the AH-3.
•The AH-4/AH-3 will not operate on frequencies outside
of ham bands.
w Push [TUNER] for 1 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 and the AH-4/AH-3 is bypassed. At that point the antenna wire connection is to
the transceiver directly, and not via the AH-4/AH-3 antenna tuner.
r
To bypass the AH-4/AH-3 manually, push
[TUNER].
[TUNER]
•ANTENNA TUNER OF THE IC-PW1
When using an external antenna tuner such as the
IC-PW1’s tuner, tune with the external antenna tuner,
while the internal tuner is turned OFF. After tuning is
completed, turn the internal tuner ON. Otherwise,
both tuners tune simultaneously and correct tuning
may not be obtained.
See the instruction manual included with each antenna tuner for their respective operations.
