FOREWORD
Thank you for making the IC-7700 your radio of choice. We hope you agree
with Icom’s philosophy of “technology first.” Many hours of research and devel-
opment went into the design of your IC-7700.
DFEATURES
❍Ultimate receiver performance: third-order intercept (IP3) of
+40 dBm (HF bands only)
❍Built-in Baudot RTTY and PSK31 modulator/demodulator
and direct PC keyboard connection capability for RTTY and
PSK31 operations without a PC
❍High resolution spectrum scope — center frequency and fixed
frequency modes, plus mini-scope displays
IMPORTANT
READ THIS INSTRUCTION MANUAL CAREFULLY before at-
tempting to operate the transceiver.
SAVE THIS INSTRUCTION MANUAL. This manual contains important
safety and operating instructions for the IC-7700.

An LCD filter has been added to European versions for Electromagnetic interference (EMI) and Radio
Frequency interference (RFI) compliance purpose. In some instances, the LCD may be a little difficult to see,
but this is normal and does not indicate an LCD malfunction.
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 equipment 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 guarantee 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 interference by one or more of the following measures:
•Reorientorrelocatethereceivingantenna.
•Increasetheseparationbetweentheequipmentandreceiver.
•Connecttheequipmentintoanoutletonacircuitdifferentfromthattowhichthereceiverisconnected.
•Consultthedealeroranexperiencedradio/TVtechnicianforhelp.
WORD DEFINITION
RDANGER! Personaldeath,seriousinjuryoranexplosionmayoccur.
RWARNING! Personal injury, fire hazard or electric shock may occur.
CAUTION Equipment damage may occur.
NOTE Recommended for optimum use. No risk of personal inju-
ry, fire or electric shock.
ii
PRECAUTIONS
RDANGER HIGH RF VOLTAGE! NEVER
attach 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 vol-
umelevels.Hearingexpertsadviseagainstcontinu-
oushighvolumeoperation.Ifyouexperiencearinging
in your ears, reduce the volume or discontinue use.
RWARNING! NEVER operate or touch the
transceiver with wet hands. This may result in an elec-
tric shock or damage to the transceiver.
RWARNING! NEVER let metal, wire or other ob-
jects protrude into the transceiver or into connectors
on the rear panel. This may result in an electric shock.
RWARNING! 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.
CAUTION: NEVER put the transceiver in any un-
stable place (such as on a slanted surface or vibrated
place). This may cause injury and/or damage to the
transceiver.
CAUTION: NEVER put the transceiver’s rear
panel side down after lifting up the transceiver by
holding rack mounting handle. This may scratch the
surface of the place or damage the connectors on the
transceiver’s rear panel.
CAUTION: NEVER change the internal settings
of the transceiver. This may reduce transceiver per-
formance and/or damage to the transceiver.
In particular, incorrect settings for transmitter circuits,
such as output power, idling current, etc., might dam-
agetheexpensivefinaldevices.
The transceiver warranty does not cover any prob-
lems caused by unauthorized internal adjustment.
CAUTION: NEVER block any cooling vents on the
top, rear or bottom of the transceiver.
CAUTION: NEVERexposethetransceivertorain,
snow or any liquids.
CAUTION: NEVER install the transceiver in a
place without adequate ventilation. Heat dissipation
may be reduced, and the transceiver may be dam-
aged.
CAUTION:Thetransceiverweighsapprox.22.5kg
(50 lb). Always have two people available to carry, lift
or turn over the transceiver.
CAUTION: The line-voltage receptacle must be
near the transceiver and must be easily accessible.
Avoidextensioncords.
DO NOT
use harsh solvents such as benzine or al-
cohol when cleaning, as they can damage the trans-
ceiver’s surfaces.
DO NOT push the PTT switch when you don’t actu-
ally desire to transmit.
DO NOT use or store the transceiver in areas with
temperatures below ±0°C (+32°F) or above +50°C
(+122°F).
DO NOTplacethetransceiverinexcessivelydusty
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 inadvert-
ent use by children.
BE CAREFUL! If you use a linear amplifier, set the
transceiver’s RF output power to less than the linear
amplifier’smaximuminputlevel,otherwise,thelinear
amplifier will be damaged.
BE CAREFUL! touch the transceiver top cover when
transmitting continuously for long periods of time. The
top cover may be hot.
Use Icom microphones only (supplied or optional).
Other manufacturers’ microphones have different pin
assignments, and connection to the IC-7700 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 [I/O] switch (on the rear panel) OFF and/or dis-
connect the AC power cable from the AC outlet when
you will not use the transceiver for long period of time.
For U.S.A. only

notexpresslyapprovedbyIcomInc.,couldvoidyour
authority to operate this device under FCC regula-
tions.

tions during transmit. (p. 3-10)
➥Switches the multi-function digital
meter ON or OFF when pushed and
held for 1 sec. (p. 3-10)

or bypasses them. (p. 5-9)
•“P.AMP1”activates10dBpreamp.
•“P.AMP2”activates16dBhigh-gain
preamp.
➥Turns the preamp function OFF when
pushed and held for 1 sec. (p. 5-9)
✔What is the preamp?
The preamp amplifies signals in the receiver front end to
improve S/N ratio and sensitivity. Select “P. AMP1” or “P.
AMP2” when receiving weak signals.
MF4 (MULTI-FUNCTION 4 SWITCH)
➥ Selects a 6 dB, 12 dB or 18 dB at-
tenuator when pushed. (p. 5-9)
➥ Turns the attenuator function OFF
when pushed and held for 1 sec.
(p. 5-9)
✔What is the attenuator?
The attenuator prevents a desired signal from being dis-
torted when very strong signals are near the desired fre-
quency, or when very strong electromagnetic fields, such
as from a broadcasting station, are near your location.

MF5 (MULTI-FUNCTION 5 SWITCH)
➥ Activates and selects a fast, mid
or slow AGC time constant when
pushed. (p. 5-11)
•IntheFMmode,only“FAST”isavailable.
➥Selects the AGC set mode when
pushed and held for 1 sec. (p. 5-11)
The AGC time constant can be set
between 0.1 and 8.0 sec. (depending
on the mode), or turned OFF. When the
AGC is “OFF,” the S-meter does not
function.
✔What is the AGC?
The AGC controls the receiver gain to produce a con-
stant audio output level, even when the received signal
strength varies dramatically. Select “FAST” for tuning and
then select “MID” or “SLOW,” depending on the receiving
condition.
MF6 (MULTI-FUNCTION 6 SWITCH)
➥ Turns the speech compressor ON or
OFF in the SSB mode. (p. 6-5)
➥ Switches the compression between
narrow, mid or wide when pushed and
held for 1 sec.
✔What is the speech compressor?
The speech compressor compresses the transmitter
audio input to increase the average audio output level,
to increase talk power. This function is effective for long-
distance communication or when propagation conditions
are poor.
➥ Turns the 1⁄4-speed tuning function
ON or OFF in the SSB data, CW,
RTTY and PSK modes. (p. 3-6)
