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.
SAVETHIS INSTRUCTION MANUAL.This manual contains important
safety and operating instructions for the IC-7700.

FCC INFORMATION
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 instruc-
tions, 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 recep-
tion, 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:
• 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.

WORD DEFINITION
RDANGER! Personal death, serious injury or an explosion may occur.
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
during a lightning storm. It may result in an electric
shock, cause a fire or damage the transceiver. Always
disconnect the power source and antenna before a
storm.
RWARNING! NEVER operate the transceiver
with a headset or other audio accessories at high vol-
ume levels. Hearing experts advise against continu-
ous high volume operation. If you experience a ringing
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 perfor-
mance and/or damage to the transceiver.
In particular, incorrect settings for transmitter circuits,
such as output power, idling current, etc., might dam-
age the expensive final devices.
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: NEVER expose the transceiver to rain,
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: The transceiver weighs approximately
22.5 kg (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.
Avoid extension cords.
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 NOT place the transceiver in excessively dusty
environments or in direct sunlight.
DO NOT place the transceiver against walls or put-
ting anything on top of the transceiver.This may over-
heat 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’s maximum input level, otherwise, the linear
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
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.
