• 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 reason-
able protection against harmful interference in a residential
installation. This equipment generates, uses and can radi-
ate 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 in-
stallation. 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 re-
ceiver.

OPERATING THEORY
Electromagnetic radiation which has frequencies of
20,000 Hz (20 kHz*) and above is called radio frequency
(RF) energy because it is useful in radio transmissions. The
IC-RX7 receives RF energy from 0.150 MHz* to 1300 MHz
and converts it into audio frequency (AF) energy which in
turn actuates a loudspeaker to create sound waves. AF en-
ergy is in the range of 20 to 20,000 Hz.
*kHz is an abbreviation of kilohertz or 1000 hertz, MHz is abbrevia-
tion of megahertz or 1,000,000 hertz, where hertz is a unit of fre-
quency.
OPERATING NOTES
The IC-RX7 may receive its own oscillated frequency, result-
ing in no reception or only noise reception, on some fre-
quencies.
The IC-RX7 may receive interference from extremely strong
signals on different frequencies or when using an external
high-gain antenna.

■Caution
• RDANGER! Use and charge only specified Icom battery
packs with Icom radios. Only Icom battery packs are tested
and approved for use with Icom radios. Using third-party or
counterfeit battery packs may cause smoke, fire, or cause
the battery to burst.
DBattery caution
• RDANGER! DO NOT hammer or otherwise impact the
battery. Do not use the battery if it has been severely im-
pacted or dropped, or if the battery has been subjected to
heavy pressure. Battery damage may not be visible on the
outside of the case. Even if the surface of the battery does
not show cracks or any other damage, the cells inside the
battery may rupture or catch fire.
• RDANGER! NEVER use or leave battery pack in areas
with temperatures above +60˚C (+140˚F). High tempera-
ture buildup in the battery, such as could occur near fires
or stoves, inside a sun heated car, or in direct sunlight
may cause the battery to rupture or catch fire. Excessive
temperatures may also degrade battery performance or
shorten battery life.
• RDANGER! DO NOT expose the battery to rain, snow,
seawater, or any other liquids. Do not charge or use a wet
battery. If the battery gets wet, be sure to wipe it dry before
using.
• RDANGER! NEVER incinerate a used battery pack since
internal battery gas may cause it to rupture, or may cause
an explosion.
• RDANGER! NEVER solder the battery terminals, or
NEVER modify the battery pack.This may cause heat gen-
eration, and the battery may burst, emit smoke or catch
fire.
• RDANGER! Use the battery only with the receiver for
which it is specified. Never use a battery with any other
equipment, or for any purpose that is not specified in this
instruction manual.
• RDANGER! If fluid from inside the battery gets in your
eyes, blindness can result. Rinse your eyes with clean
water, without rubbing them, and see a doctor immediately.
• WARNING! Immediately stop using the battery if it emits
an abnormal odor, heats up, or is discolored or deformed. If
any of these conditions occur, contact your Icom dealer or
distributor.
• WARNING! Immediately wash, using clean water, any part
of the body that comes into contact with fluid from inside
the battery.
Misuse of Lithium-Ion batteries may result in the fol-
lowing hazards: smoke, fire, or the battery may rupture.
Misuse can also cause damage to the battery or degra-
dation of battery performance.

• WARNING! NEVER put the battery in a microwave oven,
high-pressure container, or in an induction heating cooker.
This could cause a fire, overheating, or cause the battery
to rupture.
• CAUTION! Always use the battery within the specified
temperature range for the receiver (–10˚C to +60˚C; +14˚
F to +140˚F) and the battery itself (–20˚C to +60˚C; –4˚F to
+140˚F). Using the battery out of its specified temperature
range will reduce the battery’s performance and battery
life.Please note that the specified temperature range of the
battery may exceed that of the receiver. In such cases, the
receiver may not work properly because it is out of its oper-
ating temperature range.
• CAUTION! Shorter battery life could occur if the battery
is left fully charged, completely discharged, or in an ex-
cessive temperature environment (above +50˚C; +122˚F)
for an extended period of time. If the battery must be left
unused for a long time, it must be detached from the radio
after discharging.You may use the battery until the battery
indicator shows half-capacity, then keep it safely in a cool
dry place with the below temperature range.
–20˚C (–4˚F) to +50˚C (+122˚F) (within a month).
–20˚C (–4˚F) to +35˚C (+95˚F) (within three months).
–20˚C (–4˚F) to +20˚C (+68˚F) (more than a year).
DCharging caution
• RDANGER! NEVER charge the battery pack in areas with
extremely high temperatures, such as near fires or stoves,
inside a sun heated car, or in direct sunlight. In such en-
vironments, the safety/protection circuit in the battery will
activate, causing the battery to stop charging.
• WARNING! DO NOT charge or leave the battery in the re-
ceiver beyond the specified time for charging. If the battery
is not completely charged by the specified time, stop charg-
ing and remove the external DC power from the receiver.
Continuing to charge the battery beyond the specified time
limit may cause a fire, overheating, or the battery may rup-
ture.
• CAUTION! DO NOT charge the battery outside of the
specified temperature range: +5˚C to +35˚C (+41˚F to
+95˚F). Icom recommends charging the battery at
+25˚C (+77˚F). The battery may heat up or rupture if
charged out of the specified temperature range. Addition-
ally, battery performance or battery life may be reduced.

■Charging
Prior to using the receiver for the first time, the battery pack
must be fully charged for optimum life and operation.
DBattery indicator and charging indicator
When the receiver’s power is ON, the battery indicator
shows “ ,” “ ” and “ (disappears)” in sequence
while charging, and indicator disappears when completely
charged.
When the receiver’s power is OFF, the charging indicator
shows “ ,” “ ” and “ ” in sequence with “Charg-
ing...” while charging, and indicator disappears when com-
pletely charged.
DCharging note
• Be sure to turn the receiver power OFF.
Otherwise the battery pack will not be charged completely or takes
longer to charge time periods.
• External DC power operation becomes possible when
using an optional CP-18A/E.The attached battery pack is
also charged simultaneously.
• If your battery pack seems to have no capacity even after
being charged, fully charge the battery pack again. If the
battery pack still does not retain a charge (or very little), a
new battery pack must be purchased.
qInsert the battery pack (BP-244) into the receiver. (p. 2)
wPlug the battery charger (BC-149A/D*) into an AC outlet;
or the optional CP-18A/E into a cigarette lighter socket.
* Not supplied with some versions.
eTurn OFF the receiver, then insert the adapter plug into
[DC 6V] of the receiver.
CAUTION: BE SURE to disconnect the CP-18A/E from
the cigarette lighter socket when charging is finished, be-
cause, a slight current still follows in the CP-18A/E and
the vehicle’s battery will become exhausted.
