FCC INFORMATION
• FOR CLASS B UNINTENTIONAL RADIATORS:
This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant to
part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful
interference in a residential installation. This equip-
ment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance
with the instructions, may cause harmful interference
to radio communications. However, there is no guar-
antee that interference will not occur in a particular
installation. If this equipment does cause harmful
interference to radio or television reception, which can
be determined by turning the equipment off and on,
the user is encouraged to try to correct the interfer-
ence by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment
and receiver.
• Connect the equipment into an outlet on a
circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV
technician for help.

PRECAUTIONS
R WARNING HIGH RF VOLTAGE! NEVER
attach an antenna or internal antenna connector
during transmission. This may result in an electrical
shock or burn.
R WARNING! NEVER
operate the transceiver
with a headset or other audio accessories at high
volume levels. Hearing experts advise against continu-
ous high volume operation. If you experience a ringing
in your ears, reduce the volume or discontinue use.
R WARNING! Immediately turn the transceiver
power OFF and remove the power cable if it emits an
abnormal odor, sound or smoke. Contact your Icom
dealer or distributor for advice.
R CAUTION! NEVER put the transceiver in
any unstable place (such as on a slanted surface or
vibrated place). This may cause injury and/or damage
to the transceiver.
R CAUTION! NEVER change the internal
settings of the transceiver. This may reduce trans-
ceiver 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 prob-
lems caused by unauthorized internal adjustment.
R CAUTION! NEVER apply AC power to the
[DC13.8V] socket on the transceiver rear panel. This
could cause a fire or damage the transceiver.
R CAUTION! NEVER apply more than 16 V DC,
such as a 24 V battery, to the [DC13.8V] socket on
the transceiver rear panel. This could cause a fire or
damage the transceiver.
R CAUTION! NEVER
let metal, wire or other
objects protrude into the transceiver or into connectors
on the rear panel. This may result in an electric shock.
R CAUTION! NEVER block any cooling vents
on the top, rear or bottom of the transceiver.
R CAUTION! NEVER expose the transceiver to
rain, snow or any liquids.
R CAUTION! NEVER
install the transceiver in a
place without adequate ventilation. Heat dissipation
may be reduced, and the transceiver may be damaged.
R CAUTION! NEVER operate or touch the trans-
ceiver with wet hands. This may result in an electric
shock or damage to the transceiver.
DO NOT use chemical agents such as benzine
or alcohol when cleaning the IC-7600, as they can
damage the transceiver’s surfaces.
DO NOT push the PTT switch when you don’t actu-
ally desire to transmit.
DO NOT use or place the transceiver in areas with
temperatures below ±0°C (+32°F) or above +50°C
(+122°F).
DO NOT place the transceiver in excessively dusty
environments or in direct sunlight.
DO NOT place the transceiver against walls or
putting anything on top of the transceiver. This may
overheat the transceiver.
Always place unit in a secure place to avoid inadver-
tent use by children.
BE CAREFUL! If you use a linear amplifier, set the
transceiver’s RF output power to less than the linear
amplifier’s maximum input level, otherwise, the linear
amplifier will be damaged.
BE CAREFUL! The heatsink will become hot when
operating the transceiver continuously for long peri-
ods of time.
Use Icom microphones only (supplied or optional).
Other manufacturers’ microphones have different pin
assignments, and connection to the IC-7600 may
damage the transceiver or microphone.
The LCD display may have cosmetic imperfections
that appear as small dark or light spots. This is not a
malfunction or defect, but a normal characteristic of
LCD displays.
During maritime mobile operation, keep the trans-
ceiver and microphone as far away as possible from
the magnetic navigation compass to prevent errone-
ous indications.
Turn the transceiver power OFF and/or disconnect
the DC power cable when you will not use the trans-
ceiver for long period of time.
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 regula-
tions.

N 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 equip-
ment included with the IC-7600, see ‘Supplied acces-
sories’ on p. ?? of this manual.
N Selecting a location
Select a location for the transceiver that allows ade-
quate air circulation, free from extreme heat, cold, or
vibrations, and away from TV sets, TV antenna ele-
ments, radios and other electromagnetic sources.
The base of the transceiver has adjustable feet for
desktop use. Set the feet to one of two angles depend-
ing on your operating preference.
N Grounding
To prevent electrical shock, television interference
(TVI), broadcast interference (BCI) and other prob-
lems, ground the transceiver through the GROUND
terminal on the rear panel.
For best results, connect a heavy gauge wire or strap
to a long ground 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 connec-
tion could cause an explosion or electric shock.
[GND]
N Antenna connection
For radio communications, the antenna is of critical im-
portance, along with output power and receiver sensi-
tivity. Select antenna(s), such as a well-matched 50 ø
antenna, and feedline. We recommend 1.5:1 or better
of Voltage Standing Wave Ratio (VSWR) on your oper-
ating bands. The transmission line should be a coaxial
cable.
When using a single antenna, use the [ANT1] connec-
tor.
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 tran-
sistors. In this case, an antenna tuner is useful to
match the transceiver and antenna. Low SWR allows
full power for transmitting. The IC-7600 has an SWR
meter to monitor the antenna SWR continuously.

N Selecting an operating band
The triple band stacking register provides 3 memories
for each band key, storing frequency and mode infor-
mation.
This function is convenient when you operate 3 oper-
ating modes on one band. For example, one register
is used for a CW frequency, another for a SSB fre-
quency and the other one for a RTTY frequency.
If a band key is pushed once, the frequency and oper-
ating mode last used are called up. When the key is
pushed again, another stored frequency and operat-
ing mode are called up.
See the table below for a list of the bands available
and the default settings for each band.

D 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’s your responsibility to set all controls so that trans-
mission in this band meets the stringent conditions
under which amateur operations may use these fre-
quencies.
NOTE: We recommend that you store these fre-
quencies, mode and filter settings into memory
channels for easy recall.
* The FCC specifies center frequencies on the
5 MHz band. However, the IC-7600 displays car-
rier frequency. Therefore, tune the transceiver to
1.5 kHz below the specified FCC channel center
frequency.

• “Z” appears when the quick tuning function is ON.
w Rotate the main dial to change the frequency in
programmed kHz steps.
e Push [TS] again to turn the quick tuning function
OFF.
• “Z” disappears.
r Rotate the main dial for normal tuning if desired.
D Selecting “kHz” step
q Push [TS] to turn the quick tuning function ON.
• “Z” appears when the quick tuning function ON.
w Push and hold [TS] for 1 sec. to enter quick tuning
step set mode.
• Selected tuning steps for all modes appear.
e Select the desired operating mode.
r Rotate the main dial to select the desired tuning
step.

N Repeater operation
A repeater retransmits a received signal on a differ-
ent 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 transmit frequency
shifted to the repeater's receive frequency.
For accessing a repeater which requires an access
tone, set the tone frequency in tone frequency set
mode as described below.

About the “P.AMP2”
The “P.AMP 2” is a high gain receive amplifier. When
the “P.AMP 2” is used in the presence of strong elec-
tromagnetic 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 signals are
weak.
• Receive sensitivity is insufficient when using low-
gain antennas, or while using a narrow band
antenna (such as small loop, a Beverage antenna
or a short Yagi antenna).
N Attenuator
The attenuator prevents a desired signal from distor-
tion when very strong signals are near the desired
frequency or when very strong electromagnetic fields,
such as from broadcast stations near your location.
± Push [ATT] (MF4) several times to set the attenua-
tor 6 dB, 12 dB, 18 dB or attenuator OFF.

N Twin PBT operation
<MODE> SSB/CW/RTTY/PSK/AM
PBT (Passband Tuning) electronically narrows the IF
passband width by shifting the IF frequency slightly
outside of the IF filter passband to reject interference.
The IC-7600 uses DSP for the PBT function. Moving
both [TWIN-PBT] controls to the same position shifts
the IF both above and below the received frequency.
± The LCD shows the passband width and shift fre-
quency graphically.
• The indicator on the [PBT-CLR] switch lights when
PBT is in use.
± Push and hold [FILTER] for 1 sec. to enter the filter
set screen. Current passband width and shift fre-
quency is displayed in the filter set screen.
± To set the [TWIN-PBT] controls to the center posi-
tions, push and hold [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
(SSB/CW/RTTY/PSK modes) or 100 Hz (AM mode)
steps.
• The [TWIN-PBT] controls 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 the [TWIN-PBT] controls, noise may
occur. This comes from the DSP unit and does not
indicate an equipment malfunction.

N Noise blanker
<MODE> SSB/CW/RTTY/PSK/AM
The noise blanker eliminates pulse-type noise such
as the noise from car ignitions. The noise blanker is
not available for FM mode.
± Push [NB] to turn the noise blanker function ON
and OFF.
• The indicator on this switch lights green when when the
noise blanker is ON.
When using the noise blanker, received signals
may be distorted if they are excessively strong or
for other types of noise than impulse. Turn the
noise blanker OFF, or set the noise blanker thresh-
old level (see below) to a shallow position in this
case.
D NB set mode
To deal with various type of noise, attenuation level
and noise blanking duration can be set in NB set
mode.
q Push and hold [NB] for 1 sec. to enter NB set
mode.

N Noise reduction
The noise reduction function reduces random noise
components and enhances desired signals which are
buried in noise. The DSP performs the random noise
reduction function.
q Push [NR] to turn the noise reduction ON.
• The indicator on this switch lights green.
w Rotate the [NR] control to adjust the noise reduc-
tion level.
e Push [NR] to turn the noise reduction OFF.
• The indicator goes off.
Large rotations of the [NR] control results in audio
signal masking or distortion. Set the [NR] control
for maximum readability.
N Dial lock function
The dial lock function prevents frequency changes
by accidental movement of the tuning dial. The lock
function electronically locks the dial.
± Push and hold [SPEECH/LOCK] for 1 sec. to tog-
gle the dial lock function ON and OFF.
• The [LOCK] indicator lights when the dial lock
function is in use.
NOTE: When “LOCK/SPEECH” is selected in
[[SPEECH/LOCK] Switch] item in others set mode,
pushing [SPEECH/LOCK] activates the dial lock
function. (p. ??)
