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 installation. This equip-
ment 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 guar-
antee 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 interfer-
ence 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.

dom, Germany, France, Spain, Russia and/or other countries.

PRECAUTIONS
RWARNING HIGH RF VOLTAGE! NEVER
attach an antenna or internal antenna connector
during transmission. This may result in an electrical
shock or burn.
RWARNING! NEVER operate the transceiver
with a headset or other audio accessories at high
volume levels. Hearing experts advise against continu-
ous high volume operation. If you experience a ringing
in your ears, reduce the volume or discontinue use.
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.
RCAUTION! NEVER put the transceiver in
any unstable place (such as on a slanted surface or
vibrated place). This may cause injury and/or damage
to the transceiver.
RCAUTION! NEVER change the internal
settings of the transceiver. This may reduce trans-
ceiver performance and/or damage to the transceiver.
In particular, incorrect settings for transmitter circuits,
such as output power, idling current, etc., might
damage the expensive final devices.
The transceiver warranty does not cover any prob-
lems caused by unauthorized internal adjustment.
RCAUTION! NEVER apply AC power to the
[DC13.8V] socket on the transceiver rear panel. This
could cause a fire or damage the transceiver.
RCAUTION! NEVER apply more than 16 V DC,
such as a 24 V battery, to the [DC13.8V] socket on
the transceiver rear panel. This could cause a fire or
damage the transceiver.
RCAUTION! NEVER let metal, wire or other
objects protrude into the transceiver or into connectors
on the rear panel. This may result in an electric shock.
RCAUTION! NEVER block any cooling vents
on the top, rear or bottom of the transceiver.
RCAUTION! NEVER expose the transceiver to
rain, snow or any liquids.
RCAUTION! NEVER install the transceiver in a
place without adequate ventilation. Heat dissipation
may be reduced, and the transceiver may be damaged.
RCAUTION! NEVER operate or touch the trans-
ceiver with wet hands. This may result in an electric
shock or damage to the transceiver.
DO NOT use chemical agents such as benzine
or alcohol when cleaning the IC-7600, as they can
damage the transceiver’s surfaces.
DO NOT push the PTT switch when you don’t actu-
ally desire to transmit.
DO NOT use or place the transceiver in areas with
temperatures below ±0°C (+32°F) or above +50°C
(+122°F).
DO NOT place the transceiver in excessively dusty
environments or in direct sunlight.
DO NOT place the transceiver against walls or
putting anything on top of the transceiver. This may
overheat the transceiver.
Always place unit in a secure place to avoid inadver-
tent use by children.
BE CAREFUL! If you use a linear amplifier, set the
transceiver’s RF output power to less than the linear
amplifier’s maximum input level, otherwise, the linear
amplifier will be damaged.
BE CAREFUL! The heatsink will become hot when
operating the transceiver continuously for long peri-
ods of time.
Use Icom microphones only (supplied or optional).
Other manufacturers’ microphones have different pin
assignments, and connection to the IC-7600 may
damage the transceiver or microphone.
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.
During maritime mobile operation, keep the trans-
ceiver and microphone as far away as possible from
the magnetic navigation compass to prevent errone-
ous indications.
Turn the transceiver power OFF and/or disconnect
the DC power cable when you will not use the trans-
ceiver for long period of time.
For U.S.A. only
CAUTION: Changes or modifications to this device,
not expressly approved by Icom Inc., could void your
authority to operate this device under FCC regula-
tions.

available for other modes.
• 12 to 1 o’clock position is recommended for any setting
of the [RF/SQL] control.
• The control can be set as ‘Auto’ (RF gain control in
SSB, CW and RTTY; squelch control in AM and FM)
or squelch control (RF gain is fixed at maximum) in set
mode as follows. (p. ??)
