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 ob-
served when operating this device. If you have any questions
regarding RF exposure and safety standards please refer
to the Federal Communications Commission Office of Engi-
neering and Technology’s report on Evaluating Compliance
with FCC Guidelines for Human Radio Frequency Electro-
magnetic Fields (OET Bulletin 65).
RWARNING! NEVER operate the transceiver while driv-
ing a vehicle. Safe driving requires your full attention—any-
thing 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 discontinue use.
RWARNING! NEVER apply AC power to the [DC13.8V]
socket 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] socket on the transceiver rear panel or use reverse
polarity. This could cause a fire or damage the transceiver.
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 transceiver
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 distributor for advice.
CAUTION: NEVER connect or use the supplied HM-151
(microphone) with other transceiver. This could cause dam-
age to the transceiver. The HM-151 is designed for use with
the IC-7000 ONLY.
CAUTION: NEVER expose the transceiver to rain, snow
or any liquids.
CAUTION: NEVER change the internal settings of the
transceiver. This may reduce transceiver performance and/
or damage to the transceiver.
DO NOT use harsh solvents such as benzine or alcohol 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 temper-
atures 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 anything
on top of the transceiver. This will obstruct heat dissipation.
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 rear panel will become hot when operat-
ing 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-7000 may damage the transceiver.
