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 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 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 interference 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.
An LCD filter has been added to European versions for Electromagnetic interference (EMI) and Radio
Frequency interference (RFI) compliance purpose. In some instances, the LCD may be a little difficult to see,
but this is normal and does not indicate an LCD malfunction.

PRECAUTIONS
R
WARNING HIGH RF VOLTAGE! NEVER
attach an antenna or internal antenna connector
during transmission. This may result in an electrical
shock or burn.
R
CAUTION!
The transceiver weighs approx. 22.5
kg (50 lb). Always have two people available to carry,
lift or turn over the transceiver.
R
CAUTION!
The line-voltage receptacle must be
near the transceiver and must be easily accessible.
Avoid extension cords.
R
WARNING! NEVER
operate the transceiver
with a headset or other audio accessories at high vol-
ume levels. Hearing experts advise against continu-
ous high volume operation. If you experience a ringing
in your ears, reduce the volume or discontinue use.
DO NOT
use chemical agents such as benzine or
alcohol when cleaning the IC-7700, as they can dam-
age the transceiver’s surfaces.
R
WARNING!
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.
DO NOT
push the PTT switch when you don’t actu-
ally desire to transmit.
AVOID
using or storing the transceiver in areas with
temperatures below ±0°C (+32°F) or above +50°C
(+122°F).
R
CAUTION! NEVER
put the transceiver in any
unstable place (such as on a slanted surface or vi-
brated place). This may cause injury and/or damage
to the transceiver.
AVOID
placing the transceiver in excessively dusty
environments or in direct sunlight.
R
CAUTION! NEVER
put the transceiver’s rear
panel side down after lifting up the transceiver by
holding rack mounting handle. This may scratch the
surface of the place or damage the connectors on the
transceiver’s rear panel.
AVOID
placing 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 inadvert-
ent use by children.
R
CAUTION!
NEVER
change the internal set-
tings of the transceiver. This may reduce transceiver
performance and/or damage to the transceiver.
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.
In particular, incorrect settings for transmitter circuits,
such as output power, idling current, etc., might dam-
age the expensive final devices.
Use Icom microphones only (supplied or optional).
Other manufacturers’ microphones have different pin
assignments, and connection to the IC-7700 may
damage the transceiver or microphone.
The transceiver warranty does not cover any prob-
lems caused by unauthorized internal adjustment.
R
CAUTION!
NEVER
touch the transceiver top
cover when transmitting continuously for long periods.
The top cover may be hot.
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.
R
CAUTION!
NEVER
let metal, wire or other ob-
jects protrude into the transceiver or into connectors
on the rear panel. This may result in an electric shock.
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.
R
CAUTION!
NEVER
block any cooling vents on
the top, rear or bottom of the transceiver.
R
CAUTION!
NEVER
expose the transceiver to
rain, snow or any liquids.
Turn [I/O] switch (on the rear panel) OFF and/or dis-
connect the AC power cable from the AC outlet when
you will not use the transceiver for long period of time.
R
CAUTION!
NEVER
install the transceiver in a
place without adequate ventilation. Heat dissipation
may be reduced, and the transceiver may be dam-
aged.
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.
R
CAUTION!
NEVER
operate or touch the trans-
ceiver with wet hands. This may result in an electric
shock or damage to the transceiver.
