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 instal-
lation. 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 inter-
ference will not occur in a particular installation. If this equip-
ment 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 inter-
ference by one or more of the following measures:

PRECAUTIONS
RDANGER HIGH VOLTAGE! NEVER touch an an-
tenna or internal antenna connector during transmission. This
may result in an electrical shock or burn.
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 stan-
dards please refer to the Federal Communications
Commission Office 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 while
driving a vehicle. Safe driving requires your full attention—
anything less may result in an accident.
RWARNING! NEVER operate the transceiver with
an earphone, headphones or other audio accessories
at high volume levels. Hearing experts advise against
continuous high volume operation. If you experience a
ringing in your ears, reduce the volume level or discon-
tinue use.
RWARNING! NEVER apply AC power to the [DC 13.8V]
connector on the transceiver rear panel. This could cause a
fire or damage the transceiver.
RWARNING! NEVER apply more than 16 V DC to the
[DC13.8V] connector on the transceiver rear panel. This could
cause a fire or damage the transceiver.
RWARNING! NEVER reverse the DC power cable po-
larity when connecting to a power source. This could cause a
fire or damage the transceiver.
RWARNING! NEVER cut the DC power cable between
the DC plug and fuse holder. If an incorrect connection is
made after cutting, the transceiver might be damaged.
RWARNING! NEVER let metal, wire or other objects
touch any internal part or connectors on the rear panel of the
transceiver. This may result in an electric shock or this could
cause a fire or damage the transceiver.
RWARNING! NEVER operate or touch the trans-
ceiver with wet hands. This may result in an electric
shock or may damage the transceiver.
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 dis-
tributor for advice.
CAUTION: NEVER expose the transceiver to rain, snow
or any liquids.
CAUTION: NEVER change the internal settings of
the transceiver. This may reduce transceiver perfor-
mance and/or damage to the transceiver.
DO NOT operate the transceiver near unshielded elec-
trical blasting caps or in an explosive atmosphere.
DO NOT use harsh solvents such as benzine or al-
cohol to clean the transceiver, as they will damage the
transceiver’s surfaces. If the transceiver becomes dusty
or dirty, wipe it clean with a soft, dry cloth.
DO NOT use or place the transceiver in areas with tem-
peratures below –10°C (+14°F) or above +60°C (+140°F). Be
aware that temperatures on a vehicle’s dashboard can ex-
ceed +80°C (+176°F), resulting in permanent damage to the
transceiver if left there for extended periods.
DO NOT place the transceiver in excessively dusty environ-
ments or in direct sunlight.
DO NOT place the transceiver against walls or putting any-
thing on top of the transceiver. This will obstruct heat dissipa-
tion.
Place the transceiver in a secure place to avoid inadvertent
use by children.
During mobile operation, NEVER place the transceiver
where air bag deployment may be obstructed.
During mobile operation, DO NOT place the transceiver
where hot or cold air blows directly onto it.
During mobile operation, DO NOT operate the transceiver
without running the vehicle’s engine. When the transceiver’s
power is ON and your vehicle’s engine is OFF, the vehicle’s
battery will soon become exhausted.
Make sure the transceiver power is OFF before starting the
vehicle engine. This will avoid possible damage to the trans-
ceiver by ignition voltage spikes.
During maritime mobile operation, keep the transceiver and
microphone as far away as possible from the magnetic navi-
gation compass to prevent erroneous indications.
BE CAREFUL! The Main unit will become hot when oper-
ating the transceiver continuously for long periods of time.
BE CAREFUL! If a linear amplifier is connected, set the
transceiver’s RF output power to less than the linear ampli-
fier’s maximum input level, otherwise, the linear amplifier will
be damaged.
Use Icom microphones only (supplied or optional). Other
manufacturer’s microphones have different pin assignments,
and connection to the IC-7100 may damage the transceiver.

*1When the SEND terminal controls the inductive load (such as a relay), a counter-electromotive force can cause
the transceiver’s malfunction or damage. To prevent this, we recommend adding a switching diode, such as an
“1SS133,” on the load side of the circuit to the counter-electromotive force absorption.
When the diode is added, a switching delay of the relay may occur. Be sure to check its switching action before
operation.
