PRECAUTIONS
R WARNING HIGH RF VOLTAGE! NEVER
attach an antenna or internal antenna connector dur-
ing transmission. This may result in an electrical shock
or burn.
R WARNING! NEVER
with a headset or other audio accessories at high vol-
ume levels. Hearing experts advise against continuous
high volume operation. If you experience a ringing in
your ears, reduce the volume or discontinue use.
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.
CAUTION NEVER
stable place (such as on a slanted surface or vibrated
place). This may cause injury and/or damage to the
transceiver.
CAUTION NEVER
the transceiver. This may reduce transceiver perfor-
mance and/or damage to the transceiver.
In particular, incorrect settings for transmitter circuits,
such as output power, idling current, etc., might dam-
age the expensive final devices.
The transceiver warranty does not cover any problems
caused by unauthorized internal adjustment.
CAUTION NEVER
when transmitting continuously for long periods. The
top cover may be hot.
CAUTION
The transceiver weighs approx. 25 kg
(55 lb). Always have two people available to carry, lift
or turn over the transceiver.
CAUTION
The line-voltage receptacle must be near
the transceiver and must be easily accessible. Avoid
extension cords.
CAUTION NEVER
protrude into the transceiver or into connectors on the
rear panel. This may result in an electric shock.
CAUTION NEVER
top, rear or bottom of the transceiver.
CAUTION NEVER
snow or any liquids.
CAUTION NEVER
install the transceiver in a place
without adequate ventilation. Heat dissipation may be
reduced, and the transceiver may be damaged.

CAUTION NEVER
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 al-
cohol when cleaning the IC-7800, as they can damage
the transceiver's surfaces.
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).
AVOID placing the transceiver in excessively dusty
environments or in direct sunlight.
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 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.
Use Icom microphones only (supplied or optional).
Other manufacturers' microphones have different pin
assignments, and connection to the IC-7800 may dam-
age 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 [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.
For U.S.A. only
CAUTION:
Changes or modifications to this de-
vice, not expressly approved by Icom Inc., could void
your authority to operate this device under FCC regu-
lations.
