HF/50 MHz TRANSCEIVER

i
Thank you for choosing this Icom product. The IC-7300 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-7300 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-7300.
FEATURES
•RF Direct Sampling System
The IC-7300 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.
•Real-Time Spectrum Scope
The spectrum scope is class-leading in resolution,
sweep speed and dynamic range. When you touch the
scope screen on the intended signal, the touched area is
magnied. The large 4.3 inch color TFT touch LCD offers
intuitive operation.
•New “IP+” Function
The new IP Plus function improves 3rd order intercept
point (IP3) performance. When a weak signal is received
adjacent to strong interference, the AD converter is
optimized against signal distortion.
•Class Leading RMDR and Phase Noise
Characteristics
The RMDR is improved to about 97dB (typical value) and
Phase Noise characteristics are also improved about
15dB (at 1 kHz frequency separation) compared to the
IC-7200.
•A 4.3 inch touch panel color display
•A built-in automatic antenna tuner
•Multi-function control for easy settings

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! Immediately turn OFF the transceiver power
and remove the DC power cable from the transceiver if it
emits an abnormal odor, sound or smoke. 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 souce and antenna before a storm.
CAUTION: NEVER expose the transceiver to rain, snow or
any liquids.
CAUTION: NEVER change the internal settings of the
transceiver. This could reduce transceiver performance
and/or damage to the transceiver. The transceiver warranty
does not cover any problems caused by unauthorized
internal adjustments.
CAUTION: NEVER install or place the transceiver in a
place without adequate ventilation, or block any cooling
vents on the top, rear, sides or bottom of the transceiver.
Heat dissipation may be reduced and damage the
transceiver.
CAUTION: NEVER use harsh solvents such as Benzine or
alcohol when cleaning, as they will damage the transceiver
surfaces.
CAUTION: NEVER leave the transceiver in areas with
temperatures below –10°C (+14°F) or above +60°C
(+140°F) for mobile operations.
CAUTION: NEVER place the transceiver in excessively
dusty environments. This could damage the transceiver.
DO NOT place the transceiver against walls or putting
anything on top of the transceiver. This may overheat the
transceiver.
BE CAREFUL! The Main unit will become hot when
operating the transceiver continuously for long periods of
time.
CAUTION: If you use a linear amplier, set the
transceiver’s RF output power to less than the linear
amplier’s maximum input level, otherwise a high input
could damage the linear amplier.
CAUTION: Use only Icom supplied or optional
microphones. Other manufacturer’s microphones may have
different pin assignments, and could damage the connector
and/or the transceiver.
NEVER leave the transceiver in an insecure place to avoid
use by unauthorized persons.
Turn OFF the transceiver’s power and/or disconnect the AC
power cable when you will not use the transceiver for a long
period of time.
Turn OFF the transceiver’s power and/or disconnect the DC
power cable when you will not use the transceiver for long
period of time.

Selecting a location
Select a location for the transceiver that allows
adequate air circulation, free from extreme heat, cold
or vibrations, and other electromagnetic sources.
The transceiver has a stand for desktop use.
Stand
CAUTION: NEVER carry the transceiver by holding the
stand, dials, controls and so on. This may damage them.
Heat dissipation
Grounding
To prevent electrical shock, television
interference (TVI), broadcast
interference (BCI) and other
problems, ground the transceiver
using the ground terminal [GND] 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.
RWARNING! NEVER connect the [GND] terminal
to a gas or electric pipe, since the connection could
cause an explosion or electric shock.
