EXPLICIT DEFINITIONS
WORD
DEFINITION
R WARNING
Personal injury, fire hazard or electric
shock may occur.
CAUTION
NOTE
Equipment damage may occur.
If disregarded, inconvenience only. No
risk or personal injury, fire or electric
shock.
PRECAUTIONS
R WARNING HIGH VOLTAGE! NEVER attach 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.
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.
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.
NEVER expose the transceiver to rain, snow or any
liquids.
BE CAREFUL! The heatsink will become hot when operating the transceiver continuously for long periods.
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.
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.
AVOID placing the transceiver in excessively dusty environments or in direct sunlight.
Use Icom microphones only (supplied or optional).
Other manufacturer’s microphones have different pin
assignments, and connection to the IC-756PROII may
damage the transceiver.
AVOID placing the transceiver against walls or putting
anything on top of the transceiver. This will obstruct
heat dissipation.
Spurious may be received near the following frequencies.
These are made in the internal circuit and does not indicate a
transceiver malfunction:
6.144 MHz, 8.000 MHz,
12.288 MHz, 12.890 MHz (when spectrum scope is ON),
18.433 MHz, 24.573 MHz

INSTALLATION AND CONNECTIONS
■ Unpacking
■ Antenna connection
After unpacking, immediately report any damage to the
delivering carrier or dealer. Keep the shipping cartons.
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.
For a description and a diagram of accessory equipment included with the IC-756PROII, see ‘Supplied accessories’ 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.
When using 1 antenna, use the [ANT1] connector.
CAUTION: Protect your transceiver from lightning
by using a lightning arrestor.

■ Grounding
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.
R WARNING: NEVER connect the [GND]
terminal to a gas or electric pipe, since the connection could cause an explosion or electric shock.
14
Strip the cable as
shown at left. Soft solder the center conductor.
solder solder
To prevent electrical shock, television interference
(TVI), broadcast interference (BCI) and other problems, ground the transceiver through the GROUND
terminal on the rear panel.
Slide the coupling ring
down. Strip the cable
jacket and soft solder.
30 mm ≈ 9⁄8 in 10 mm ≈ 3⁄8 in 1–2 mm ≈ 1⁄16 in
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-756PROII has an SWR meter to monitor the antenna SWR continuously.

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-756PROII 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. 56) or the
memory transfer function (see p. 54). 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.
MEMORY MODE (pgs. 51–55)
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 a VFO is selected from another band or memory mode, the frequency and operating mode last
used for that VFO appear.
When the memory channel is selected from another
memory channel or VFO mode, the memorized frequency and operating mode appear.

If a band key is pushed once, the frequency and
mode last used are called up. When the key is
pushed again, another stored frequency and mode
are called up.
This function is convenient when you operate 3
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.

■ 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 frequency 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 positions, push [PBT CLR] for 1 sec.
AM/FM
Push mode switch
for 1 sec.
Push mode switch
momentarily.
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 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
■ AGC function
The AGC (auto gain control) controls receiver gain to
produce a constant audio output level even when the
received signal strength is varied by fading, etc.
The transceiver has 3 AGC characteristics (time constant; fast, mid, slow) for non-FM mode.
The FM mode AGC time constant is fixed as
‘FAST’ (0.1 sec.) and AGC time constant cannot be
selected.

■ 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 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.
w Push [SPLIT] for 1 sec.

Regarding the use of the “P.AMP 2”
(Pre-amplifier 2)
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 shorten Yagi antenna, etc.) is used.

each for transmit and receive, of digital voice memories. A maximum message of 15 sec. can be recorded
in each receive channels, and total message 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.

■ 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.

■ 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.
TUNER OPERATION
➥ Push the [TUNER] switch to turn the internal antenna tuner ON. The antenna is tuned automatically when the antenna SWR is higher than 1.5:1.
CAUTION: NEVER transmit with the tuner ON
when no antenna is connected. This will damage
the transceiver. Be careful of the antenna selection.
[TUNER] switch
• When the tuner is ON, the [TUNER] switch lights.
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.
➥ 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 1.5:1
after 20 sec. of tuning, the [TUNER] switch indicator
goes out.
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. 71).
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. 71).
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.

above) or more than 12 m/40 ft long (1.8 MHz and
above).
• See p. 19 for the transceiver and AH-4/AH-3 connection.
• See the AH-4/AH-3 instruction manual for AH-4/AH-3 installation and antenna connection details.
AH-4/AH-3 setting example:
• 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

• 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.
[TUNER] switch
R WARNING: 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 1⁄2 λ long wire or multiple of the operating frequency.
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 [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.

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. 73)
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].
Displayed frequency and mode
Push
USB
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] several times.
MEMO PADS
• 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.

For programmed scan:
Program scan edge frequencies into scan edge memory channels P1 and P2.
Scan speed can be selected from 2 levels, high or low,
in set mode. See p. 61 for details.
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
• Squelch condition

Scan stops when detecting a signal.
If you set scan resume ON in set mode, the
SQUELCH scan pauses for 10 sec. when detecting a
CLOSED signal, then resumes. When a signal disappears while scan is paused, scan resumes
2 sec. after.
You can select the scan to resume or cancel when detecting a signal, in set mode. Scan resume ON/OFF

INSTALLATION NOTES
For amateur base station installations it is recommended that
the forwards clearance in front of the antenna array is calculated
relative to the EIRP (Effective Isotropic Radiated Power). The
clearance height below the antenna array can be determined in
most cases from the RF power at the antenna input terminals.
As different exposure limits have been recommended for different frequencies, a relative table shows a guideline for installation considerations.
Below 30 MHz, the recommended limits are specified in terms of
V/m or A/m fields as they are likely to fall within the near-field region. Similarly, the antennae may be physically short in terms of
electrical length and that the installation will require some antenna matching device which can create local, high intensity
magnetic fields. Analysis of such MF installations is best considered in association with published guidance notes such as the
FCC OET Bulletin 65 Edition 97-01 and its annexes relative to
amateur transmitter installations. The EC recommended limits
are almost identical to the FCC specified ‘uncontrolled’ limits and
tables exist that show pre-calculated safe distances for different
antenna types for different frequency bands. Further information
can be found at http://www.arrl.org/.
• Typical amateur radio installation
Exposure distance assumes that the predominant radiation pattern is forwards and that radiation vertically downwards is at
unity gain (sidelobe suppression is equal to main lobe gain). This
is true of almost every gain antenna today. Exposed persons are
assumed to be beneath the antenna array and have a typical
height to 1.8 m.

In all cases any possible risk depends on the transmitter being
activated for long periods. (actual recommendation limits are
specified as an average during 6 minutes) Normally the transmitter is not active for long periods of time. Some radio licenses
will require that a timer circuit automatically cuts the transmitter
after 1–2 minutes etc.
Similarly some types of transmitter, SSB, CW, AM etc. have a
lower ‘average’ output power and the assessed risk is even
lower.
Versions of the IC-756PROII which display the “CE”
