i7610
HF/50 MHz TRANSCEIVER

i
Thank you for choosing this Icom product. The IC-7610 HF/50 MHz TRANSCEIVER is designed and built with
Icom’s state of the art technology and craftsmanship. With proper care, this product should provide you with
years of trouble-free operation. We appreciate you making the IC-7610 your transceiver of choice, and hope you
agree with Icom’s philosophy of “technology rst.” Many hours of research and development went into the design
of your IC-7610.
FEATURES
•RF Direct Sampling System
The IC-7610 employs an RF direct sampling system.
RF signals are directly converted to digital data and
processed in the FPGA. This system is a leading
technology marking an epoch in amateur radio.
•2 identical receivers
The IC-7610 has 2 independent receiver circuits for the
Main and Sub bands.
•A built-in DIGI-SEL unit
Both the Main and Sub receivers have built-in DIGI-SEL
(digital preselector) units. These reject interfering signals.
•Real-Time Spectrum Scope
Displays the Main and Sub band conditions. It provides
class-leading performance in resolution, sweep speed and
provides a 100 dB dynamic range.
•A built-in automatic antenna tuner
•Multi-function control for easy settings
•Extra large 7 inch touch screen color display
•External monitor connection with a DVI-D port
•BNC type RX IN/OUT connectors
•Class Leading RMDR and Phase Noise
Characteristics
•IP remote control capability with the optional
RS-BA1 ip remote control software
•Remote encoder capability with the optional
RC-28 remote encoder
•Dualwatch operation

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:
• 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
RDANGER HIGH RF VOLTAGE! NEVER touch an
antenna or antenna connector while transmitting. This could
cause an electrical shock or burn.
RDANGER! NEVER operate the transceiver near
unshielded electrical blasting caps or in an explosive
atmosphere. This could cause an explosion and death.
RWARNING 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
Ofce of Engineering and Technology’s report on
Evaluating Compliance with FCC Guidelines for Human
Radio Frequency Electromagnetic Fields (OET Bulletin 65).
RWARNING! NEVER operate the transceiver with a
headset or other audio accessories at high volume levels. If
you experience a ringing in your ears, reduce the volume or
discontinue use.
RWARNING! NEVER apply AC power to the [DC13.8V]
socket on the transceiver rear panel. This could cause a re
or damage the transceiver.
RWARNING! NEVER apply more than 16 V DC to the
[DC13.8V] socket on the transceiver rear panel. This could
cause a re or damage the transceiver.
RWARNING! NEVER reverse the DC power cable
polarity. This could cause a re or damage the transceiver.
RWARNING! NEVER remove the fuse holder on the DC
power cable. Excessive current caused by a short could
cause a re or damage the transceiver.
RWARNING! NEVER let metal, wire or other objects
contact the inside of the transceiver, or make incorrect
contact with connectors on the rear panel. This could cause
an electric shock or damage the transceiver.
RWARNING! NEVER operate or touch the transceiver
with wet hands. This could cause an electric shock or
damage to the transceiver.
RWARNING! NEVER operate the equipment if you notice
an abnormal odor, sound or smoke. Immediately turn OFF
the power and/or remove the DC power cable. Contact your
Icom dealer or distributor for advice.
RWARNING! NEVER put the transceiver on an unstable
place where the transceiver may suddenly move or fall.
This could cause an injury or damage the transceiver.
RWARNING! NEVER operate the transceiver during a
lightning storm. It may result in an electric shock, cause
a re or damage the transceiver. Always disconnect the
power source and antenna before a storm.
CAUTION: DO NOT expose the transceiver to rain, snow
or any liquids. They could damage the transceiver.
CAUTION: DO NOT change the internal settings of the
transceiver. This may reduce transceiver performance and/
or damage the transceiver. The transceiver warranty does
not cover any problems caused by unauthorized internal
adjustments.
CAUTION: DO NOT install the equipment in a place
without adequate ventilation, or block any cooling vents
on the top, rear, sides or bottom of the transceiver or the
cooling fan. Heat dissipation may be reduced and damage
the transceiver.
CAUTION: DO NOT use harsh solvents such as benzine or
alcohol when cleaning. This could damage the equipment
surfaces. If the surface becomes dusty or dirty, wipe it clean
with a soft, dry cloth.
CAUTION: DO NOT place or leave the transceiver in
areas with temperatures below 0°C (32°F) or above 50°C
(122°F).
CAUTION: DO NOT place the transceiver in excessively
dusty environments, or in direct sunlight. This could
damage the transceiver.
CAUTION: DO NOT set the transceiver’s RF output power
to more than a connected linear amplier’s maximum input
level. Otherwise, the linear amplier will be damaged.
CAUTION: DO NOT use non-Icom microphones. Other
microphones have different pin assignments and may
damage the transceiver.
BE CAREFUL! The transceiver will become hot when
operating the transceiver continuously for long periods of
time.
NEVER leave the transceiver in an insecure place to avoid
use by unauthorized persons.
Turn OFF the transceiver’s power and disconnect the DC
power cable when you will not use the transceiver for long
period of time.
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.
